I have a 1991 Suburu Loyale that is fuel injection but I don’t know if it is a Single Point Fuel Injection or a Multi Point Fuel Injection. I am trying to put the fuel injection into a 1986 GL and I am wondering if the entire ECM and wiring harness needs to be swaped?
The ECM from one car/engine combination is unlikely to be appropriate for a different car/engine combination.
I agree with VDC. The 91 Loyales were equipped with TBI anyway.
