Hi, I put a centrifugal supercharger on my E39 530, and I'm not getting the advertised power above 5000rpm. The S/C dealer is 12+ hours away, and he asked me to make sure the MAF sensor connector is at the top of the intake. It's now at the 3 o'clock position, looking back from the front of the car, because the wiring harness is too short to reach the new position of the MAF. ? can the wiring harness to the MAF sensor be lengthened by splicing, or would that change the sensor's input somehow?
JA: Does the engine
stall right after starting? And what about hesitation or jerking during acceleration?
Customer: Hesitation, yes. Stall after starting, no.
JA: What year is your 530?
JA: Are you fixing your 530 yourself? What have you tried so far?
Customer: So far, just rotated the MAF from 6 o'clock to 3 o'clock.
JA: Anything else you want the mechanic to know before I connect you?
Customer: S/C delivers 6-7 psi boost, no waste gate.
