Hey Guys,
Im not a tuner but I am using HP to scan a recent engine swap that I have done. The problem is that I have a horrible MAF signal. it bounces from zero to 4000HZ constantly.
So here is a little info on the build:
The engine is a 2016 Cadillac ATS 2.0 LTG and I built the harness myself(because I couldn't find anyone to do it) and so far everything works.
I have grounded everything exceptionally well and moved to the MAF around looking for a cleaner signal. I have OHM'd the wires and there isn't any resistance in the circuit that shouldn't be there. During the replay of the LOG the signal looks stable but its not and doesn't look that way during recording. I have scanned other cars that i have around the shop and their signal is stable and consistent. Any advice would be appreciated.
