Apexi PFC hot start issues
 

Having trouble with my car (V5 STI) starting when its hot on an Apexi ECU. Swapped to the OE ECU and found an issue with the MAF which was replaced, then the car started & idled fine. Returned to the Apexi but its still got the same issues, although the MAF value readings are ok? Also tried replacing the crank & cam sensors without any improvement.

Does the Apexi store error values in a log which prevents it from clearing historical error readings?

Am I unique in the Subaru world being the only person to run an Apexi ECU?

No you're not unique. I run an Apexi with the hand controller as do many more owners

talk to your mapper or give jollygreenmonster an email should point you in the right direction
