Hello everyone!
This may seem like an odd request, but I'm helping a friend diagnose his current build (1992 Sentra SE-R w/ SC61 SR20DET).
He chose to utilize a Ford Lightning 90MM MAF since they are rated for over 700whp.
Two issues here:
1. I'm located half way across the country
2. I don't know the correct MAF voltages that should be put out from the MAF in the ACC/ON position, or the MAF voltages that should be seen at idle.
3. I can't get his car to idle at present time, so I can't determine what his idle voltages from the MAF are.
Assuming that the scale is 0-5V for the signal, it should be around .8 to 1.2VDC at idle? What then would be the ON/ACC voltage be? Most other MAF combinations we use run around .32~.4VDC in the ACC/ON position, but he can't register over .12~.17VDC regardless of whether he can get the car to idle (by holding the throttle open), or in the ACC/ON position.
Thoughts?! Thanks much in advance!
