Got my new car and it has been run on regular unleaded I reckon since new done 1600 miles.
I have put a tank of Optimax in it and not really driven it hard yet but feel its backin itself off a little at the top end of the rev range.
I would like to reset the ecu easiest way is??
Cheers.

 

Dealer only or off a laptop unfortunately
It should learn pretty quickly though when you put super in there

I think I`ll get some more "harder" miles on it first it is still very new and tight.
Get that super juice through it ;-))))

 

Thought about disconnecting the battery but it seems the car is armed a little like a tank and will probably explode!! LOL

 

As you said, give it a while and run a few tanks of V power/Super through it. Numpties running it on unleaded

 

Stick some octane booster in, give it a birthday present !

LOL

dunx

P.S. Most std. cars "back off" nearer the rev limit, that's why JGM is so popular

 

They only had regular unleaded on their very ancient pump.
They offered to give me a tank full I told em not to bother but you just know that its been on it since new!!!
Directors own car.
I have got some octane booster somewhere.......

 

You shouldn't need octane booster.......the ECU should soon re-set the IAM higher

So that dealer doesn't read the handbook.

It says 98 ron only for Sti's...

 

I bought a car in 02 from another dealer in Derby they used normal too
First time I ragged it it blew up
That was before uprated fuel pumps were part of the PPP mind you!! LOL
