Hello! We are not new to tuning, but are new users of the PCLink software. The car in question is a 2002 Subaru WRX. It starts and idles fine. It is dead lean at cruise. When it is cold, it doesn't stall but once it is warm and goes into closed loop any sudden load (such as the fans turning on) will cause it to stall.
We have modified the fuel table and solved a number of problems, but those above remain. I think that if we had the ability to tune the mass air, we could address these. Can the mass air be tuned using PCLink? Any other suggestion?
Thanks for reading.
