Q: Can't find a ecu.

asked by on

I swapped a 94 302 for a 96 351 and I need a ecu. 96 ecu won't fit into my truck and the 96 engine's oe codes don't match my truck. Can I get any ecu and just reprogram it to my truck?

My car has 290000 miles.
My car has an automatic transmission.

You can use the engine but you are going to have a hard time getting it to work since the two years are a generation apart when it comes to the computer systems. The 1994 was an OBD1 and the 1996 is an OBD2 system. The only way I see the two working is to swap all the 1994 harness and sensors to the 1996 motor and by using the 94 ECM. I still think you will have issues with the intake and some of these items. Seek out assistance from a willing mechanic, like one from YourMechanic, they may be able to help you work it out.
