You can change the reluctor on the crank back to 24x encoded and 1x cam timing gear to use the earlier computers and available freeware. Not much freeware for the newer computers at this time.
No TAC module needed on the newer computers, E38,E67,E78 and can run the larger 6 pin 4 bolt TB's.
That is good info about the ECM and Gen 4. I'll have to take a close look at this engine before I make a decision. THANK YOU!!
