VERY weird issues, ECU Guru's PLEASE HELP

Again... MAF related... either some of the stuff in the SD rom hasn't been tweaked correctly or possible bad PnP harness. try taking out the PnP SD harness and reinstall the MAF and flash a MAF rom in and see if it runs correctly.
So what does the top tuner in the world have to say about your issues?

Just check the MUT table for the one of the requests that is logging weird and see what variable it is. Check that against your last known good ROM and see if it's different.
Either you're logging incorrect variables, your cable is bad and your flashing iks corrupting the ROM, and/or SD isn't setup properly like Bryan mentioned. Seeing that you say it's a known good ROM, maybe it's one of the former choices.

The other two 2.3's i did also went over 100 just reving in neutral.
i would follow this if you want to play with it yourself: https://www.evolutionm.net/forums/ec...ched-roms.html
I got a car running very well on sd following scheides tutorial. But if you already paid Aaron, let him fix it up.

36 knock counts is the cap in the ECU. So, it's not possible to have anymore knock than that. If you or he are seeing higher than 36 then something isn't being logged correctly or the cable is bad.

Knock isnt the only thing going crazy, for example Ill get a spike where it will log 200 knock, 93rpm, 23degF coolant, 232 timing. Then the next point on the log 339degF coolant, -20 timing, 65 knock, with nothing recorded for rpm.

Again, cable or rom issue. Have you tried another cable yet??
