OLD batch fire EFI ---> new self learning brain box
My 81 TA is efi'ed about 14 yrs ago...I made everything! Holley Commander 950 Universal multi-port system. I can no longer communicate with the OLD windows XP system. I did have it running and was tuning it before the 400 DIED. as anyone swapped out from an OLD injection to a new self learning ECU? I realize the harness change but MOST of the sensors are going to be the same as they are GM basic stuff.
Any system pros?
Cons?
I am looking at the fast EZ retro-fit (fuel and spark)...right now I will drive on the Holley 850 double pumper.....till I get more money to swap.
