After Ecu Reset....

[nsta]

From what i gather, once the car has been reset(ecu)...

1) turn on car and let idle for 5-10mins

2)let car idle again for 5-10 mins with a/c on

3)take car for a spin, but just drive as you normally would, and not trash the sh*t outta it

sound correct.

im going to have to do this soon, as my car is idling like sh%t !and havent done a ecu reset for a long time

I just reset it.. idled for a min and went for a short drive.. driving normally..

everything seemed fine??

dont know why you gotta turn air con on tho?

[paulr33]

it sounds like u are getting mixed up with the apexi powerfc self idle lean procedure

the stock ecu doesnt need that

[sloutch]

what's the use of an ECU reset?

there is no use, its constantly learning, reset will do jack f**k

Last time I reset my ECU my car was pumping out some smoke for a few mins until I went for a thrash and all was well

From what I udnerstand its not a bad idea to reset ECU after some mods, ie FMIC, Zorst, Pod etc. Whether it makes a difference? Who knows. But I usually drive it hard after a reset, so it 'learns' how it should behave

[mad082]

are the skyline ecu's actually self learning? i have never read any factual evidence of the skyline ecu's actually self learning. not ecu's do. and then how much does it learn? it can't lean very much otherwise you wouldn't need aftermarket ecu's. you'd just do the mod, reset the ecu and go for a spin and it would tune itself.

The only thing the Nissan ECU's learn really is the closed loop fuel VE and ALPHAS.

They are really good ecu's in all other respects really.

With other cars however, like Holden Commodores for eg, they have to learn not only closed loop fuel VE tables, but also in particular, what voltage is closed and full throttle, how many steps the idle stepper motor should default to when AC is turned on, "D" is selected and other loads. (Resets stepper motor calibration on battery re-connect after 60km/h) Daewoos another typical example. But there is heaps.

One in particular is Subaru ECU's, they actually add timing as you drive it under certain conditions, so if you reset the ecu, the car will have less performance/power, but there is a trick, can't recall exactly, but roughly what you do is, use the brake to build boost around 3psi hold around 3500rpm for a km or so of driving, and that way, you are holding the engine in the knock learning/control zone and you can get it to go up to the maximum ignition timing tables very quickly. (good for 10-20kw atw apparently) Rather then driving it for a few weeks and finally getting up there.

But back to Nissan, not really much for them to learn apart from fuel, they are good IMHO...

I had a problem starting my car when I imported it form Japan. I did an ecu reset and it was all sweet from then on.

I think the difference in fuel between Aussie fuel and Japanese fuel was what the ECU had to learn.

just did the reset, let it idle and drove a bit on the freeway.

No worries.

AS if resetting the ecu does shit all. .

I wasnt running as rich.

Car felt a little smoother

But this only lasts for a good week lol..

then goes back to normal..
