spanish oak and MAP

[sportinawoody]

I understand that 2007-2010 gt500 also shares the same spanish oak pcm that the 05-10 gt uses. gt500 uses a MAP sensor so there should be an empty pin at i believe pin 62 of c175e connector and my ecm has a map enable/disable function on my 07 gt that may or may not open up a table with map function enabled. wondering if i wire in my gm 3bar and log it thru ecm and not my proset. Anyone have any idea if this is possible ?

GT500 does not use a MAP sensor.

i just looked in the wiring diagram and it appears there is a map input that is derived from the egr. wouldnt this mean map is not "inferred" if there is a feed into the pcm ?

They do have a supercharger inlet pressure sensor, but not map. The sip sensor will only measure up to atmospheric pressure, not boost, since it's in the supercharger inlet.

was wondering if the ecm would support boost pressure thru that input if wired to an external 3 bar. i guess what im asking is, is there range in the ecm for lets say 300+ kpa or does the ecm still only infer map above atmospheric in this ecm ?
