Powerfc... Can It F$ck Its Map Alone?

[GreeceS13]

Can powerfc f**k its map alone?

The car was mapped untill 1 bar boost with 11afr and now at 1bar the car is very very rich... lower than 8afr

At 1.2bar the car was very lean... 13afr... now still lower than 10...

At 2.1bar boost (yes danger) the car was ok.. 10.5afr and ofcourse was unbelievable fast..

But why all theese?

What happened at powerfc?

Anyone know that powerfc can destroy its map?

I have never seen this happen before. if your fc has lost its tune then it would run like crap. check the sensors and make sure the air temp and water temp is working correctly, if not then fix it.

if you have AFM's make sure they are reading correctly and working right. if i were you i'd be looking for another issue. check the FPR and fuel pressure as well.

Look for something simpler. Don't start at the ECU, it sounds like something else is telling it to go rich. ECU's don't just drop data
