ECM swapping

Im running an 87 TPI 350 auto GTA currently using EBL converted to MAP.
Is it possible to use a stock ECM from a 90-92 instead of the EBL?
Reason being, Im considering selling my car and would like to keep the EBL.

Re: ECM swapping

If you are currently using the EBL Flash ECM, will need to add a third ECM harness connector and re-pin the two connectors into three connectors.

If you are using an EBL P4 Flash ECM it is plug & play with the '90-'92 f-body EFI harness.

Since the engine/drivetrain is modified, maybe sell the car with the tuned EBL. Then just get another one for your new car.
