Modified 2001 WRX aus spec ROM - A4SE700I AF730-7574

[nod911]

Max boost raised from 13.7psi to 15.1psi at WOT. Part throttle boost raised slightly up to approx 10psi at 50% throttle. Max Wastegate duty raised down low.

Small amount of base timming added above 2K rpm and 2.3 g/rev load. timming added to ignition correction map across range.

Low det Fuel map leaned out above 2K rpm and above 2.5 g/rev load.

Much stronger midrange with more boost on part throttle. car used to stop pulling at 6K but now pulls much cleaner up high. Car is run on 98 octane fuel and IAM rock solid at 16 with no negative knock correction.

This is my 1st map for my car so any input would be greatly appreciated. maybe where I could push it a bit more or if i have set something a little high.

I didnt touch the maps below 2k rpm or 2.3 g/rev load because i figured off boost down that low there wouldnt be much to be gained. Is this correct?

Cheers.

Do you find it jerky on gear changes, especially with the A/C on ?

your low det fuel is running way richer than your high det table, it's interesting. I find good boost (on my ecu which is an 04) if I left the area under 2400 revs at 14.7 and let fuel trim sort itself out, it learns on mine but you have a different ecu and your default map is similar too. What sorts of AFR and MAP are you getting at full boost ?

I have never turned my A/C on but I find it smooth as standard when shifting, under light and heavy load.

And I never even looked at the high det fuel table but your right. That seems really weird. I leaned up the low det fuel table from about 2400 onwards so that is just how it is from the factory for some reason. I guess that maybe because when theres DET the ignition retards alot so the leaner AFR can be run more safely?? dont know just a guess.

This map is very conservative all i really done was raise boost by 1psi and leaned and advanced the map a little. There is plenty more left in this map but with my little experience i didnt want to go crazy and over do it.

I am getting about 14.9 psi and approx low 10's AFR under full boost. I know its very rich but my car is completely stock so the gains I would see from pushing the tune harder would be minimal anyway.

cool yeah. I found if I left the target boost at 1bar at low throttle in low rev range, with the A/C on gear changes, it oscillates on A/C compression. I've lowered it to 0.8 and it's perfect for my liking but everyones different and this seems to suit you fine.

Nice one...

can i flash this to a 2002 wrx

I would copy across the maps to your original rom for safey reasons instead of just straight flashing this one. Provided your running 98 RON fuel shouldnt be a problem.
