Help with Boost problem on LTX12
We were out doing some street tuning today on the car and an issue with the boost has come up.
The Greddy boost guage is showing we are at 7 to 8 pounds of boost and the microtech is showing 15 to 17 pounds. There is no way we are actually hitting 15 to 17 lbs of boost but the ECU doesn't know that. It's treating the timing and fuel like its under higher boost.
We datalogged a few runs...one things we noticed that seems odd is the voltage on the datalog is only around 12 volts. I am thinking it should be north of 13 volts.
If the ECU isn't seeing enough voltage could it have an impact on how it's reading boost.
Any help would be greatly appreciated...
