Did you wire the gm sensor into the OEM wiring?

the stock timing is 15 deg at idle. shouldn't be much of a issue.

yeah you find out what 2 MAF wires are actually IAT and wire sensor into those

simple enough. You sell the mating pigtail for the maf so i dont have to cut and splice it?

Thanks for the quick replies! You must have notifications set up...

Looking at the gm sensors, 1 chart says the numbers match closely but when i go to the vednors the numbers (resitance at said temp) is off.

what now?

in the haltech setup you would put in the value of the new temp sensor.

for GM the setting is already there you just hit load and go through all the pre installed sensor settings map sensors temp sensors maf sensors all kinda sensors in there.

Oh, was planning on installing into the OEM wires and replacing the oem Thermistor with one with the same values.

Dont have my haltech software in front of me on work laptop so not sure about setting the params. I set the params for boost, widebands so i am familiar with that aspect.
