I've been all over the forums looking for this answer and I'm sure somebody else has come across it.
The LS2 cars do not have a 2 bar or 2.5 bar PID i understand that but how do you properly scale the map sensor in that case in the scanner.
Everything points to the sensor reading 80kpa when it should be reading 40 and 160 when it should be reading 80.
At first glance I would assume the sensor is stock and not reading correctly but then I've verified and tried 2 different 2 bar cobalt ss sensors.
Never had an issue like this....
Before you scream at me for show me your config file...lets talk generalities so we can help anybody else with this issue.
uploading a histogram does you no good if its still documenting values above 105kpa that are not actually boost on the gauge....the point here is to actually tune the correct cells at the correct pressure.
The histogram is pulling the exact same value as the graph....furthurmore the computer is behaving like those are actually the cells its tuning from. I'm having to scale the MAP table in half to get it to trim back to previous?
Back to the computer reading the wrong sensor would be the assumption while setup for 2 bar. sensor is 12615136 (revised gm number for the ss cobalt) . Stock sensor is reading the same??? but I've got 2 of these sensors and a duralast su1078...have i just been steered wrong on the sensor P/N?
I've got to ask...is there a glitch in the 2 bar OS? what am I missing...I've gone back to stock with the one exception ....it was previously patched for 15000HZ for a larger MAF.
I'll upload my files but they are a mess as I've been feeling around with this trying to find home so no grief over final tune this or that...this is purely to find home and figure out the MAP scaling.
Feeling like a moron who's never touched one of these cars...please help!
