Hey guys, I need a favor.
When I look in GAP, my "Bank 1 MAF Voltage" is showing as a negative 30 V - this obviously makes no sense. Some additional info:
1. I can switch MAF's side to side and this doesn't change anything
2. The Bank 1 and Bank 2 "MAF grams per hour" figures are virtually symmetric so it appears that the ECU is reading the incoming airflow properly
3. There are no MAF codes being thrown
I don't know if all L320's have dual MAF's, so if your car has a single MAF then you won't be able to help me.
I have contacted the GAP folks and this was their response:
"The IIDTool provides the same live value LRmade available thus we have no control over how they show up on the IIDTool. If both reading in g/s are identical, theissue is elsewhere. Also, the ECU will always show a fault when this type ofissue is present. In other words, issue is elsewhere."
While I understand the logic of his response, I find it hard to believe that if the ECU is actually being presented with a Bank 1 MAF voltage of -30V that it wouldn't throw a code! I feel like there is a bug in the GAP software, but perhaps I'm wrong.
Could someone test this for me? If you have a dual MAF L320 could you compare Bank 1 and Bank 2 MAF voltage?
