Yes and no.TheWoo said:i was told that resetting the ECU will give increased performance if bought used and if the previous driver drove conservatively. he told me by resetting the ecu the computer will have to re learn the driving style of the driver. Is this true?
Only if your enigne was pinging/knocking/detonating on the lower octane.Neil82 said:hhhmmm if you are going to be using a higher octane petrol resetting the ecu may give u some performance increase...
Actually, Sunoco sells 94 in some areas of the US and there are even places that sell "race gas" that is 100 octane. I put race gas in quotes because it will not pass tech at a lot of venues if they sample fuel. A bunch of karting friends got caught out by that.cas8_1999 said:damnnnnnn they sell 98 on the street where you live here in us max is 93 at local gas stations
Xard said:I've heard that you can go to airports sometimes and buy aircraft fuel, which is apparently much higher octane than normal gasoline. For a while I was considering driving my fathers old 1973 Grand Am, and it would require super high octane fuel to run decently, because it's a 6.5 Liter V8.
Of course, you can ALSO buy octane booster, which will increase the octane of fuel you have in the gastank.
Nah. You may. You may not. It all depends upon how far away the currently learned adjustments are from the base settings. More likely than not it won't make a difference or the current learning is closer.95_g20_P10 said:if you ad performance parts you should reset your ECU and you will see a diff once reset
I'm not 100% sure about a P11, but the FSM should have a description of how to do it yourself. The P10, B13, and B14 FSMs do.95_g20_P10 said:the best thig would be to go to a mechanic and have them do it. they use some special machine that they hook up to it and it resets it the best. also it very quick and easy
Higher revs huh? So resetting the ECU raises the rev limit? :/95_g20_P10 said:even when i just added my intake i noticed my idle was a bit to high, i got the ecu rest when i got my Greddy put and i noticed a cleaner idle and quick, higher revs
The ECU will read the O2 sensor(s) and other sensors trying to optimize the fuel/air ratio over the range of the map. They are relatively small changes.cas8_1999 said:so just veryfying this to be sure to reset we can just disconect battery for 30 mins and it will be reset?
now the thing is we have an answer (sort of)
but what is it exactly that the comp learns about the driver or the mods does it check how hard i press on brakes to adjust to my style of braking or etc.. u get what i'm saying
so since the comp has these capabilities what are its limitations and if it can relearn the mods then why do we have to send it to JWT after some mods for increased power
what is it that JWT does to the comp do they program it with some machine or do they install a chip in there or do they just take out some microchip for rev limiter and etc.............
...i think you get my drift
thank you very much for the past replies if you dont feel like replying please postt where we can read about this
There are different facts to look at when doing this. The information gathered from various threads when resetting an ECU is as follows:cas8_1999 said:so just veryfying this to be sure to reset we can just disconect battery for 30 mins and it will be reset?
