Combined PCM - can you combine engine and transmission tunes from different vehicles?
edit: I'm wrong on some of my information in this first post. Updating this to save anyone else going down the wrong path.
Hi all,
I'm researching swapping a W5A580 (Nag1) transmission into my 2012 Durango R/T, to replace the 65RFE.
For the 2012 model year, the v6 Durango with the 3.6 pentastar was sold with the W5A580 transmission.
Physically, the PCM units for the 5.7 and 3.6 look the same (4 connectors), which is at least a lot closer than the separate ECM and TCM units found on later models with the 8 speed transmission. edit: It now looks like the PCM in the 3.6 has, but doesn't use the green transmission connector.
I'll start the pinout comparison shortly.
For now, my question is - even though it's a combined PCM unit, could I theoretically flash it with the transmission 'tune' from a v6 and the engine 'tune' from a v8 using HP tuners?
thank you very much.
