Either leaving out this feature altogether at compile time, or manually turning it off via the sensor page in MPGuino (if it was compiled in), will enable MPGuino to read VSS and injector signals.

I think that Jeeps have slightly different fuel pressure specifications than the Dodge I used for development. 49 psig for fuel pressure, IIRC. My Dodge used 58 psig.
I think that’s correct. I’m excited to try out the barometric pressure adjustment once I get everything dialed in. I did have a thought, my jeep has a fuel rail pressure port I could hook a pressure sensor up to. My thought was that this could provide more accurate injector g/h data because of the Chrysler fuel pressure setup. Do you think this would work the way that I’m thinking, and would it be any more accurate than MAP/barometric pressure correction?

Also, just found the newer thread for your mpguino code, I suppose I’ll post there from now on as I’m using version 1.95
