Hello,

So I have recently put in a wideband and it is constantly running at around anywhere from 13.6 to 14.3 afr. I have eliminated the fuel system and am basically down to the maf and the ecu. I tested the voltage coming out of the maf going to the ecu and it’s reading 1.6v on idle and throttle, it doesn’t fluctuate. Anyone know what the voltage should be reading? Obviously more than 1.6v on throttle.

cheers!
 
I unplugged the sensor and it didn’t make a difference. I have a fpr fitted, tried upping the pressure to 50, 60 and 75 and no change
 
ok then, if all those are good, MAF would be a good starting point.

what you measuring is the air volume, there's also a air temp signal from maf, have you measured that one as well?
