Hi All,
I seem to have a problem with my stock ADM MY07 WRX. I have been logging it over the last few weeks with the objective of doing a stage 1 on it in the near future and I want to make sure the car is ok before doing so. Through one of the very helpful guides that has been developed, the author suggested that I make sure my MAF scalings are correct before going any further and it seems I do in fact have a problem.
After resetting the ECU and allowing it to settle in (couple of days normal driving), I am finding that Learning View and ROM Raider are telling me that I am running rich across all scales (A-D) by about anywhere from -8% to -11%. It seems that the car is pulling fuel and I am at a loss as to why. As mentioned, the car, intake and the map are both completely stock. Still even using the stock air filter.
I was wondering whether one of you tuning gurus might be able to give me some pointers on trying to rectify. Couple of things that may help:
Running 98 ron (same as us 93?)
I'm a semi high climate - 600 metres ASL
Temps are currently quite low (winter) and these measurements have been in temps of freezing up to 12 degs.
Recently cleaned the MAF sensor with sensor cleaner - made no difference.
Thanks. I look forward to your reply.
Lachlan.
