LS3/Powrmaf Swap I want to verify that I am doing the wiring conversion correctly. The wiring to the Powrmaf is as follows:
A. Yellow MAF Signal
B. Black white stripe Ground
C. Pink +5V
D. Purple Ground
E. Tan IAT
My stock wiring (2004 CTS-V) is as follows
A. Yellow MAF Signal
B. Black/white Ground
C. Pink IGN 1 Voltage
D. Tan Low Reference
E. Tan IAT Signal
I have looked at a bunch of threads but it is hard to find one where someone actually follows through and posts all of the needed info and whether or not it works. I am assuming that the ppl-gnd in the LS3 sensor is the same as tan-lowref .
I also just download HPtuners 2.23 beta which will allow me to change the IAT calibration which is 15% different than stock.

I have the HPtuners beta now and I scaled the IAT sensor curve by 85%. That much is done. I actually got everything hooked up and I am still using my Volant cold air box but had to modify it some.
