MAF problem
 

I'm going to try and explain myself in my best english :Suspiciou

I had a mapper coming this weekend to map my apexi power FC. he has lots off experiance in mapping power FC and other ECU's.

now the problem he had with my car he has never seen before! the first run my maf broke and the car was dead :)

second run was with a new maf and the milivolts who came in werent good :(

on wastegate pressure (0.6) I had on 6000rpm a voltage from 4.6 that came in the ECU. that's the limmit of the maf I reached... you have that on cars with 400BHP but not on wastegatepressure. when he putted up the boost with the AVCR it was boost cutting on 4000 RPM...

he doesnt know an answer anymore, maybe someone here...

whats the full spec of your car/engine/turbo/injectors etc.? The MAF should read up to the full 5 volts but your injectors could be maxed out before that giving you the fuel cut around 4000rpm.

Nothing special...

Oem 99 block, 440 injectors, fmic, open 2,5, vf30

still having the same problem with the OEM ECU.

I installed an AFR gauge to look what is does when I put up the boost. normal driving around 13. when I hit the pedal it goes to 10 and much lower. checked my MAF voltages and they go to high :(

So I think my MAF tells my ECU to put allot of feul in my engine because there is coming allot of air in it. something like that...

tyred of riding around on wastegate pressure :(
