Hi, pardon my ignorance. I've ordered a Magnuson supercharger, and I assume the factory MAP sensor is a 1 bar which will read up to atmospheric but what sensor do I need to pick up that will bolt in like the stock L9H (12711681) and what needs to be done tune-wise as far as being able to read and display that through HP tuners? 2 bar is all I need at the truck will only ever boost below 10ish psi. Thank you.
Just buy a GM ZR1/ZL1 style 3 bar MAP sensor. It's the red top MAP sensor. Plug in the correct data for it and that's all you gotta do.
I believe the LSA ones have been discontinued, or are at least much more difficult to find now. The ZR1 part number seems to be a lot easier to find nowadays. 55567257Quote:

Sure, but what tables in the ECM use 'boost' in PSIG? This is like getting stuck with thinking in AFR. The ECM doesn't use it, nothing you need to adjust in the ECM is helped by knowing either AFR or boost in gauge pressure.
I don't care if the ECM doesn't use it, I like to have psi so I don't have to do math in my head from kpa to psi. Maybe HPTuners put that function in there for me.
