Hellcat-swapped 2007 300 SRT
I have here a 2007 SRT8 with Hellcat V8 swapped. Don't know much of the details and it has multiple issues, so far biggest one is that the PCM does not read boost.
Original MAP sensor wiring was first connected to the upper left side of the supercharger, part number being 68207074AB, which I think is a baro sensor and does not read boost. I switched wiring to the MAP sensor located on the rear left of the manifold (which I guess it's the same as right front of the intake manifold). That part number is 53010887AA which I think is a 3 bar Hellcat sensor.
Now, the PCM does not allow 3 bar settings, as it is limited to around 2.2 bar. Because of that Key On Engine Off shows 82 kpa which is less than athmospehre (which is around 100 kpa).
Even with that there's no boost readings, i.e. it is somehow limited to naturally aspirated max values.
Tune and log attached.
