I have a 93 firebird, running a torqhead 24x system and 0411 pcm. For all intents and purposes think of it as an Ls1 in regards to my question. So far i got the pcm from the ju kyard, found out it was from a v6 4.3. So i flashed it to an pem calibration (i work at gm so i used a vin i found for an ls1 firebird and treated it as a blank ecm)
So now its running a 12212156 OS. I found out the vin i used is for a 6 speed. Should i leave it as is? Or flash it again with a stock cal from an auto ls1 car? I spent extra time wiring in my vss properly and making sure the 1993 4l60 (not e) has the current PRNDL switch wired in to the ecm. The wiring actually matched exactly going from 93 to 02 diagrams. The 93 non electric 4l60 was a crossover to the 94 mpdel year 60e, it had a tv cable, but also a few pressure switches inside the valve body, as well as a prndl switch. My reasoning for leaning toward wanting it setup this way is the ecm will see its in/out of gear and will have correct idling in gear/out of gear.
Any experience with a setup like this would be great.
