So I have had issues with the evo ecu sine the beginning. Here's the new issues.
- Omnipower 4 bar map - not reading boost correctly (evoscan)
- GM IAT Temp - always at -77 (evoscan)
- Does not always see closed TPS (won't decel all the time)
We had a very decent maf rom but after replacing the hg, the maf is dead. Is there anyway to test it?
I have checked the harness, checked all wires for issues and testpointed them to the correct areas. Map sensor is good, Omni sent me a replacement map and it did the same thing. For the decel/idle, evoscan shows the tps as correct (13.333) and the car will not idle at all times or will not catch itself when the rpms drop.
