I've searched and searched without finding an answer so I'm asking here...
I have a Bosch 2.5 BAR TMAP sensor on my E-Force supercharger that I'm trying to read correctly. I've adjusted its parameters in the editor, my question is only on the scanner. I see the 1 and 2 BAR MAP - GM PIDs but again, my sensor is a 2.5 BAR sensor. So far the best way I could figure to get realistic Absolute MAP readings is to define a User Defined PID that is ([SENS.30.KPA]*2.5)-1.65. The 1.65 is my sensor's offset. Would I be better off using the "2 BAR MAP - GM" ([AUX.20021]) and multiplying it by 1.25? The scanner help says to use generic sensors whenever possible so that's why I chose the [SENS.30]. Is there somewhere in the scanner that I can enter my sensor's specific slope and offset and apply that against [SENS.30]? I defined a couple of histograms that use my 2.5BAR_MAP PID so I think I'm OK there -- I just want to make sure I get the correct reading from my 2.5 BAR sensor. BTW, my PCM is an E67 that comes with the harness for the GMPP 430 HP crate engine and it supports MAP values up to 255 kPa. I believe I've attached my config.
Thanks for any pointers!!
