A complete map of variables was entered into the ignition program and the preset timing would be read from a table. Thus even though higher octane is in actual use, the data in ECU memory still corresponds to that of lower octane. Modern day cars do not have manual controls. Going back to the ECU hex dump, the ascending RPM numbers could be the start of a fuel map, or it could be a timing map, or possibly a map to control oil injection, at this time we don't know the definition of that map. Save your money. This is because the ECU has not been reset for higher octane. So you want to make major power gains (ie. It maxxed out the retarders yet again making over 3300 lb ft pound and the dyno rolled over. Dyno time is not cheap, but it can save you a lot of time and a lot of guessing. Yeah, you can tune a stock car. The dealer would need to mail in your ECU to Ford. You can't generalize about fuel either, because the PCM program and cam differ year-year on When you fill up you are also restricting yourself to high quality fuel and even high octane fuel if this was what the map was optimized for, and you must be prepared to replace components that fail due to the extra work they are doing. TorqueCars strongly recommend that you get a switchable remap - it may cost a little more at the outset but you will avoid many of the pitfalls of running a high power remap all of the time by doing this and get the best of both worlds. You need to see what the engine is doing in order to adjust it correctly, otherwise it is just a guess. There are many forums online on how to edit map files. This is a serious investment for serious people. Another way to return the car to stock would be with the Accessport. You should remember a few points when doing the ECU setting. Can you handle it or do you know someone who can? Typically these chips disable error reporting for most sensors and give about 40 % worse fuel economy. When an engine is tuned to produce more power, you are also creating more stress and strain, so things will start to fail such as air flow sensors. Chips cannot do this. Generally the turbo/clutch weaknesses will manifest themselves clearly at this point. Then we put the car on the dyno, tune it, run it hard….rings need PRESSURE to be able to seat so running the engine up to 75% will help those rings seat better. It allows YOU to tune YOUR car on the dyno or at the track using elapsed times between known rpm points. The only correct way is to do the reprogramming on the dyno. Make sure that the system will do what you require it to do. The ECU also activates your other CEL error codes and controls A/C & Idle/EVAP inputs/outputs. Piggy back ECUs connect between your existing ECU and the engine sensor inputs and outputs. Some will actually perform their own calculations and take over control of some aspects of engine management like turbo waste gate control and ignition timing. So what can you do? Most independent tests that I have seen on performance chips for naturally aspirated engines have indeed shown minimal or no gains in acceleration. The program commands can be entered on 2 dimenional tables. "A dyno tune would net you a solid 15 rwhp but most of all would make it run correctly/safely after installing a cold air intake, exhaust." Therefore, there are specialized shops that will take your car and tune it up on the dyno machine for you. tune used to push things. Yes they are good, but no kal is universal. Theoretically it is best to leave it in this disconnected condition for as long as you can. First a basic beginners guide introduction into world of car tuning and what you need to know: The ECU of your car is like its brain. Then there are the programmers who take advantage of import enthusiasts who do not understand the performance difference between a pre-programmed, mail-order chip versus a chip tuned and programmed on your car at a dyno. This did a sufficiently good job, but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve. Practically leaving it disconnected overnight is more than enough. Most people will run an economy map through the weekly commute and then go for a performance map at the weekend or a race map for track days. Allow your ECU to relearn and perform. Above the code area you will find the Constants and Maps, among other things. EPROMs are like ROMs except they have a quartz window which allows the EPROM to be erased and reused. Manufacturers do not want people breaking down, suffering premature parts failure or to get a reputation for uneconomical cars so they build in a wide margin of tolerance. Getting a dyno tune at Dynotech. WOT O2s are 0.880-0.890 pretty much with '02 stock tune on my car (but the hokey ported SLP MAF is in the mix too so who knows what a truly normal one would do?). To us, it seemed like a very typical muscle car engine—not quite stock, and with a past that is not entirely known. That's fine as long as you only intend to drive your car around town or don't mind breaking the law to get into whatever tuning zip code you want to be in. The main advantage of user programmable (standalone) systems is that they can be quickly changed, if a new mod is done or if not quite right whereas the factory type (mail order) chip must be changed or sent back to be redone, sometimes, several times at great cost. It allows YOU to tune YOUR car on the dyno or at the track using elapsed times between known rpm points. This is a purely hypothetical MAP for illustration only. Of course the amount of power you choose has a bearing on the reliability and cost of running the car. This lends versatility to your car- and all this at no cost. Resetting the ECU when you choose to boost Octane becomes necessary because your ECU has a memory bank for octane. The advice to stick to known reputable programmers is wise, if you plan on mail orders. call your local shop for the labour quotes. To reset the ECU you simply have to unplug the negative battery cable connection. One such instance could be when you think of boosting octane. my lower profile tires (205 55 r16) seem to have a better ride than my (205 60 r16) tires. You have to let your ECU adapt itself to the new situation arising out of the modification. Also turbos can wear out, other major components like pistons and bearings will need care and attention and you will find that the clutch lasts a shorter time. Get the chip maker to guarantee the performance gain IN WRITING and make him understand that you will return the chip to him if the chip does not work as claimed. PART 2 demonstrates example how to program ECU via HEX coding software. Investing in a wide band O2 sensor like the MOTEC they sell is also a good idea. 1. An "off the shelf" or mail order ECU is a programmer's best guess at trying to make a program that will fit as many different engine combination of mods as possible...that's why I call these "one-size-fits-all". Thats more then the 16,000 HUB NM the pro hub 4000 is Rated at. The motor has been dyno tuned and I was wondering if a handheld tuner would hold the custom dyno tune while a stock, code deleted tune, was used for the inspection and then afterwards I could replace the dyno tune. In this situation you must let the turbo cool down a little before shutting off the engine, otherwise the oil will degrade and you will have an expensive turbo repair on your hands. Or Dinan ECU - which are "best guess" chips? This means that a true stage 1 modification part does not require any other engine modifications to get it to work. It's supposed to be one of your last modifications and not one of your first, to prevent the need for multiple chip reprogrammings after each addition of a new modification. However, I had as much as 10hp and 11tq increase throughout the rest of the rpm range. Any thoughts on that as I am not computer literate. It is not designed to co for detonation under boost and may be fooled by forged pistons rattling into retarding the ignition when knock is not present. You'll first need to get familiar with this information before attempting to code (as discussed in PART 2). ECU ROM Numbers: As further identification Honda ECUs have a software revision number inside the ECU. What is a Map? Electronic ignition allows the manufacturer to fine tune economy at popular road speeds such as 30mph, 56mph and 70mph where most cars spend a large proportion of their time. Third, "Best Guess" programs are not as good. SDS and Hondata agrees with me that the best way to rechip your computer is to program your ECU instead on the dyno on your car rather than buying a previously programmed "best guess" chip made to fit as many different engine packages as possible. Understand that you will have to program all of the values to make the engine start, warm up, cruise, accelerate and run at full power. Dyno time is not cheap, but it can save you a lot of time and a lot of guessing. Fox News fires key player in its election night coverage, 'I have deep respect for a free and independent press', Advocates react to Biden's sweeping immigration plan, Democrats officially take control of the Senate, Biden leaves hidden message on White House website, Saints QB played season with torn rotator cuff, Lady Gaga wows with exuberant anthem at inauguration, Ken Jennings torched by 'Jeopardy!' Aftermarket ECUs are often direct replacements for the car's ECU and will take over all the functions associated with it. Other enthusiasts made the mistake of buying a chip too early that was not programmed correctly for the unique way their engine package breathes. When you get a new chip, the programmer has changed the program's commands of the ignition map and fuel map in response to a change in air flow and rpm (ie. If your car is a turbo model & has electronically controlled fuel injection, there are massive power gains on offer and TorqueCars would strongly recommend a remap. When we think of tuning, most people immediately think of a dyno and when we have the option to tune on a dyno, this is usually going to give you the best possible results. The advantage of such resetting made to your ECU is that your car performs the best in every climatic condition. As a tuner, a … This is usually a two or three digit number stamped on the 28 pin ROM, or main processor. The next best option would be to tune the car on a load based dyno - that's a Mustang dyno, and I think the newer Dynojets can do the same. All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. 3rd gen. GSR). Last time I went to tune on the dyno, it turned out I got the car so close that we only adjusted 3 fuel sliders a combined total of 4% fuel changes and +2 timing. You start to see the fantastic scope for improvement, when you add into the mix the fact that the average TorqueCars reader will be adding better performing components to the car, you have a really strong case for a remap. The numbers in red represent RPM values, the green numbers represent Mass Air Flow and the numbers in the yellow matrix represent fuel injector pulse width. Once you take a look at the MAP area in memory, you will see it's nearly all floats or byte values. In some cases, poor driveability and performance are the result. It comes with a chip burner, chips ($25/each), emulation laptop … 3 Typical Questions When Attempting Car Tuning: First, don't chip too early There is no point in getting a new ECU program early in your engine build up and then later upgrading to bigger lift and duration cams, or larger injectors, bigger fuel pump, or an aftermarket IM/bigger bore TB , etc. This means that if you've been using lower octane, the response of ECU will correspond to lower octane with the booster matching lower octane performance. For your car to deliver it’s best performance you have to keep it in a fit condition at all times. Expect at least 3-4 hr dyno time minimum to tune these even if you are experienced at partial and wide open throttle fuel tuning. Last time I went to tune on the dyno, it turned out I got the car so close that we only adjusted 3 fuel sliders a combined total of 4% fuel changes and +2 timing. If this happens then the ECU will compensate to some degree using closed loopo peration to reduce the injector duration. It comes with a chip burner, chips ($25/each), emulation laptop capability, instructions, and tech support. That's why if you're serious about car ECU chip tuning — you want to look into dedicated ECU chip tuning software like TOAD. LISTEN. We loaded up the car and took it to Quintin Brothers, about three hours north of Hemmings HQ, and the staff mounted it to the dyno. 37820-P72-A01 The part number consists of three components: Honda's part number for ECU, which is always 37820 Three characters (which are loosely related to the model of car/engine). If EVO is dyno tuning the car they should be able to identify what mods the car has. How do you think about the answers? If neither of these appeal to you and you insist on getting a mail order chip knowing that it won't be the best program, then stick to the known programmers (PM me if you want recommendations from people I've known who do a decent "best guess" chip). What are the biggest injectors I can run with a stock ECU? Mugen recognizes this and does not have a knock sensor (input on their ECU). The only thing that can be married to the car and thus locking it is the tuner, if the stock tune is not reloaded to the car the tuner cannot be used for another vehicle until unlocked by downloading the stock tune or sending to SCT to be unlocked. It can both increase your horsepower as well as your gas mileage and it should cost between $150.00 to $250.00 dollars. ECU Flashing / Programming / Tuning / Chiptuning Resources: Even though chip tuning is possible with any ordinary HEX editor (as described above) — the fact is it can be very time consuming, tedious and error-prone. 13-15% or at least 7 whp from midrange up) with an ECU reprogram? On the subject of turbos, (briefly though as we have a comprehensive article on turbos in the forced induction section), a remap will often introduce boost from lower down the rev range and because of this the turbo is running faster and hotter. Well thankfully there is and they are called piggy back ECU's or aftermarket ECU's. These were not designed for performance use and you will usually not get the kind of power required with factory hardware. This can be done with various piggyback ECU tuners. Be careful. 2. correct, they will be close, but theres many different factors between different cars. you wont gain very much maybe at most 10hp ,a tune will maybe get you another 1-2 hp. In a nutshell, the dyno is used to apply a load t… EEPROMs are most suitable for use when tuning a car, but can be used as the final tune as well. Remember, both the chip that you buy or the chip in your (standalone) programmable ECU must have the proper values entered for your engine to run properly. It was clunky and mechanical but seemed to work reasonably well. It will save you a lot of time. Make sure that the company has good, accessible tech support, you may need it. 2002 Nissan Maxima 3.5L V6 6-speed tranny I'm thinking of installing cat back exhaust and cold air intake only. This is part of a table. Much depends on the mechanics of the injector, and how quickly it can open and close. If all of this doesn't sound too good to you (in terms of chips), the alternative is a (standalone) programmable engine management system . ? Phone: (+61) 401 605 241 Things have moved on and it is now possible to have a few maps stored which you can select from. Removing the factory system and installing a stand alone system can be a lot of work. These are at the bottom end of the tuning scene in terms of the overall benefits you will get.Stage 1 mods are generally a straightforward DIY fit and should wor… You could install it, and uninstall it, and it would put the stock data on the car. This is a technically sound modification only if your engine has the same mechanical mods as the motor on their dyno that the chip is being developed for. These systems are great for the knowledgeable person and a nightmare for the lay person. If the stock ecu is able to be tuned then go with the dyno. Some ECU's are simply not reprogrammable. We will be adding more & more Harley charts as well as Metric & Euro charts as we go from the 2000+ bikes we have tuned over the past 2 decades. Follow all of the instructions provided by the chip maker when installing it. You could take it to the dealer and have them reflash the car to stock. They are now trying to recover the money lost from an obsolete or incompatible chip. Their dyno tuning services start at $600. This assumes that you are not re-calibrating the ECU to the new injector size. See their list of ECU tuning products here. You will get a good baseline performance increase, and you can take your car to the dyno before and after to see how much power it gained. Therefore they cannot make much difference in power output. See their list of ECU tuning products here. S2000. Car updates are done normally when the Manufacturer decides an issue can be solved. If emission compliance is a concern, ask if their chip will pass the test and get it IN WRITING. In the long run, it will be cheaper for you to pick up a wideband, DSMLink and do it yourself. Atmel AT27C256 ROMs). A perfect subject for some basic dyno testing and tuning. This means that you have to erase the old data from memory and new data pertaining to post modification should be logged into the ECU memory by mapping in new readings. The middle three characters are the most useful to identify what the ECU is. What factory options will you lose when removing the factory ECU? The ECU can be re-calibrated to suit any sized injector (make sure you match injector impedance if you are replacing you injectors). Customers must sign our Dyno waiver HERE befor running car on dyno. The same things apply as above for the mail order chips. Sometimes when you are tuning an engine that is already in a vehicle on a chassis dyno, a lot of strange things can happen that you should be aware of. You should be well versed with the vital art of resetting the ECU of your car. the fuel map (ie. Fitting a turbo timer will also help with this problem and keeps the engine ticking over. You can get ProEFI ECU tuners, the AEM Infinity 508, FuelTech and Haltech Elite, as well as a wide variety of HP Tuners. Then you have the 'sport' or 'power' modes which give lots of power and often require high octane fuel. You should prepare the ECU to get adapted only to the conditions that it would normally encounter. Here is some very good advice when buying a pre-programmed , "mail order" performance chip from SDS' website that I have found to be true: Before buying, do acceleration testing with a stopwatch, Vericom (or a GTech Pro) or at the strip. NOTE: This is only a very brief introduction to tuning. The dynamometer is not a simple machine to operate if you have never done it before. Like dyno it before tune.. and dyno it same day after tune.. then you know how much more power you got. This old data no longer is credible as it pertains to conditions that existed before the modification. Can dyno tuning increase any horsepower with those small upgrades? Below you will find an assortment of sample dyno charts for various Harley combinations, this is a work in progress. With disk type injectors (such as RC 440cc injectors) you cannot tell the difference between stock injectors and injectors which flow twice as much as stock injectors, once the ECU has been reprogrammed for the larger injectors (and there is no difference on the dyno either). It is now possible to advance the timing if the throttle is wide open to give greater power or back off the timing when cruising at constant speed for improved economy. Why an 'off the shelf' mail order ECU will disappoint: ...on most naturally aspirated engines operating on pump fuel, the only way to achieve tangible power gains is by increasing airflow through the engine. This will cost more. Can dyno tuning increase any horsepower with those small upgrades? contestant, Why some find the second gentleman role 'threatening', At least 3 dead as explosion rips through building in Madrid, Pence's farewell message contains a glaring omission. IMO. So please do not get your chip reprogrammed just after i/h/c/e , if you later plan on going for bigger & better things in the future. You will get a good baseline performance increase, and you can take your car to the dyno before and after to see how much power it gained. The idea is not to reset the ECU when using anything in your car that you normally don’t use. The longer the injector pulse the more fuel gets injected into the rotor. I let HPP turn up the rpm on their tune and it put 700/521 at the tires. Having a dyno tune completed on your car will require a hefty fee. Chip reprogrammers can richen the mixture slightly at full throttle and advance the ignition timing slightly perhaps but this would be at the expense of lowering the factory safety factors for detonation and emissions. The values 200 and 500 are not RPM based on the magnitudes (RPM would not normally be lower than 650), the values 800 thru 6400 are most likely RPM values used in a lookup table or map. Get your answers by asking now. Where can you take parts you want modded for your car to be put on? This can entail entering hundreds of points in most cases and you will require either a dyno or a long deserted road plus some indication of mixture strength to properly tune such a system. In the hex dump window you see a series of highlighted bytes, 43 7A 00 00, and in the Inspector window you see "Float  250". This is the reason why ECU resetting is essential for optimum performance after any modification has been carried out in your car. Read, understand and follow the manufacturers instructions. Honda tunes for maximum reliability out of the box, so tuning it will just make it a little bit more performance oriented (somebody correct me if i'm wrong) Crome is a obd1 eprom editor, just like hondata and uberdata. It's best for you to consult with a performance auto shop as there could be other things to consider besides the items you have listed above. If you don't, the bigger injector will over-fuel. any power gains from the chip are eliminated). This is showing a map or constant value, in 32 bit floating point format, of 250. We recommend that if your car is stock to start with the COBB AccessPORT. However, injectors take a finite amount of time to open and close, so the bigger injectors tend to be less accurate with their fueling at low durations, such as idle. So there's plenty to be had from stock, by tuning. A perfect subject for some basic dyno testing and tuning. Some maps use the cruise control to choose a map, other companies offer handheld flash devices which allow you to choose a range of maps and upload these. The next series of 4 bytes, 43 FA 00 00, is a value of 500. Different countries use different grades of fuel and have varying degrees of extreme weather conditions, all these factors add to the fudge that has to be done to keep all the cars working well across the globe. If you want to go at this alone, then an AEM EMS is worth looking into, since it has base programs and laptop emulation. There is also a 3-D fuel table (or "fuel map") which has Intake Manifold Pressure (Y-axis), RPM (X-axis), and Fuel Values instead of spark Advance (Z-axis). Still have questions? You will probably be able to do this yourself with a handheld computer for your ecu assuming again that the ecu can … This is a brief introduction on how to tune a sample car map file using a good ECU HEX editor like TOAD. my car is fairly fast for a sedan, I've raced .5.0 mustangs, bmw, gti and other cars and it does pretty good, but I want some more average price for the tune? no longer lots can help the SOHC del sol crx. the best element to do is attempt to locate a ZC engine and pay a sturdy shop to alter it out for you. I'll say this - I've dyno'd my car a few times and with a Whipple Stage 2 / Gen 2 with 3.625" - whipple tune at 7200 rpm, it put 660/521 at the tires through the automatic trans. There is a greater chance of rupturing the diaphram of the FPR (usually rated to 100 psi) dumping fuel into the intake. Even though you have made modifications in your car, the ECU still continues to get an input of the old data which is stored in it’s memory. What do these ECU program's commands look like? Many people go for an off the shelf remap which are on offer all over the country and typically cost around $260-$600. The ECU tells your engine not only what to do but also how to do it. Whenever you make a physical intervention the data pertaining to such intervention gets recorded in the memory banks of your car’s computer. Posted by Alex (Im) E. on 21 February 2013 01:09 AM. My car got 405whp on one dyno and went to another dyno it read over 440whp.. but that dyno everyone said they get higher number and even the owner of the shop said they did that because general customer like to see high number. The input data to the ECU should pertain to the post modification situation of the components and parts introduced, while making the modification. Second, What does an ECU do and what am I doing when I get a new chip ? For $800, you can rent their dyno tuning shop for a full day. The advantage of using an EPROM emulator is that the tuning information in the ECU can be changed quickly without unplugging or swapping ROMs. Other systems to consider are the Motec M4, Apex Power FC, Accel DFI, SDS EF3, and Electromotive Tec3. Once you have done this you have accomplished the ECU resetting. However if you are going to change the operating conditions on medium or long-term basis then you should reset your ECU. ECU resetting is over. What does this involve? If you got your chip by mail then, please understand that you did not get the most out of it...even the custom pre-programmed, mail-order kind of chips. There are several different types of chip which can be used to replace the factory ROM. Source: Dynotech.
