Afternoon people..

I've been deciding on whether or not to reset my ECU. My reasoning for this is that the car only recently arrived in the country and would have "learnt" on 100+ RON petrol that they have in japan.

As i'm now running the car on 98 Octane fuel the timing maps and so forth would be a bit different for what i'm running.

Because of this I was thinking of resetting the ECU this weekend and letting the car relearn it's mappings.

what i'm after is the procedure for helping the car relearn after i've reset it.

Previous posts I found this:

reset the ECU - than do

3 x 3000rpm to redline

2 x idle to redline

take the car for a decent drive..

This is what i'll probably do - does anyone have any recommendations - personally don't like free revving the car to redline - anyone have any suggestions/experiences with resetting it.

Thanks,

My 96 r33 doesnt do anything differantly after i reset the ecu. Done it a few times now, same result. Im sure it does affect some skylines however not mine..

Just wanted to let ya know incase you reset it and your waiting and waiting for something to exciting happen :D

Anyways I think once you have reset it, you can just go for a bit of a hard drive around for 30 minutes and that should do the trick.

Was about to reset it last night when I found I need a decent socket wrench to undo the battery terminal - damn the nuts on tight..

will probably do it this weekend when I can a) buy some proper tools and B) see what the hell i'm doin and there isn't a gale force wind..

I'm still tossing up whether to do it - at the moment car is running well - doesn't appear to be running rich or lean - backfire has gone away (probably from ecu learning and also just getting everything worked out - had been on a boat for 3 months and hardly driven)

So i'm weighing up as to whether it's worth the trouble - obviously won't do anything bad - but i'm pretty happy with how the car's going.

Is there a chance I could see improved fuel economy?
