a really quick question if it is even possible can you swap a 1998 honda civic ecu into a 1994 honda civic and is it even worth it.

 

Wont work, and not worth it. 94 is obdI 98 is obdII, fuel maps are entierly different.

 

It will work but is not worth it, like said above 98 is obd2 and 94 is obd1 but the fuel maps are not different enough to matter. If you need a ecu and are trying to get off cheap by buying a obd2 ecu you are screwing yourself because along with the ECU you will need to buy a obd1 to obd2 conversion harness($75 or so), change you IAVC from a 2 wire to a 3 wire, buy a O2 sensor, and run all wires to get everything hooked up.

 

yeah its just not worth it unless you are doing like an obdII swap
