For gen4 1bar map sensors i see a couple of commonly used linear/offset values. Cannot find which value to use for the common part # 12591290 MAP sensor. I see values of 128.1/-0.31 and 94.43/10.34 very commonly used in the HPtuner software checks on different LS3 tunes but never have found any information linking any of those to a specific part number sensor. Just trying to dial in my LS3 tune. Anyone know what value for that sensor?
Well one setting would be completely wrong and you'd see that with your key on engine off MAP kpa values. If you live near sea level it should be right around 100kpa.
I'm guessing it's 128.1/-0.31.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
