    Initial tests with the second MAF seems to have fixed the issue, I'll post again if I find it did not.

    After going over a few logs last night and getting my wideband dialed into HPTuners, I dont see the cranking advance being applied while running so its just referencing where it would be at .vs ECT...

    I'm not seing the IAT being erratic anywhere in the log, especially where the MAF is spiking, it went down 2deg due to me hitting the throttle and pulling in cooler air. I unrouted the MAF cable and...

    Good point on the EMI interference. If the second MAF I ordered does not fix the issue, I'll go ahead and re-run the MAF, Crank, and Cam Sensors in EMI shielded wire. Currently I have the wires...

    I thought of that, brand new MAF connector and pigtail (mine was already clipped). I even kinda tapped on the sensor to see if there was a change anywhere and nothing makes it do anything abnormal. ...

    Swap, Yes, Wiring issues, No. MAF works great other than random spikes, I built the harness and I am very confident it is not a wiring issue. Posting the log and tune here, I believe you will agree....

    should be a way to do it by using the clutch switch I would think. I'll have to look to verify but cannot right now.

    Not sure which PCM your using but did you hook up or change the low oil pressure/level cut off? Also is your Idle air control motor working? (take it out, hook it up, cycle the key to see if it moves)

    did you verify what injectors you have on the engine and tell them when they did the tune?

    are your o2 sensors hooked up and working? any exhaust leaks? we will need a log also to tell anything.
