Rom 96531706 w/sd issues!
I'm running into issues with sd in my 2g. I'm running rom 96531706 v7 with sd (option 5).
Issues:
-Fuel temp is reading -77 in evoscan, and displaying 49 in the IAT.
-OmniPower 4 bar is not reading boost accurately at all.
I have my MAP sensor in the factory location with factory wiring (I testpointed all three back to the ecu). Evoscan (2.8) is setup correct as per the thread on it. I have had this issue on EVERY rom, sd, maf, maf with map, etc. Reads vacuum like a pro, but anything near or above 0 is way off (40+ psi). Omni sent me a replacement, same thing. Any ideas?
For the Fuel temp input, I have the maf unplugged and it shows the gm iat sensor in pin 77, but the IAT (factory maf one) is correct (within reason, never found scaling for the ecu) in evoscan. Is this correct for sd? I added the IAT sensor to evoscan, but its always -77. Also, I tested with a stock maf rom and evoscan did not change from -77.
I have tried everything I can think of. I have spent over 2 months on this to just putt around, still can only idle...
