Ecu Plug And Play?

will a 90-91 si crx ecu plug into a lx sedan and work correctly? i have my old z6 and can get everything else for the swap from a wrecked 90-91 crx (trans,axles,wire harness,ecu...etc etc etc). if it will plug in i might buy it and just save it till i get a good deal on another 4th gen...

The LX harness will have to be converted to MPFI, but other than that, it will plug up to the ECU with no problem

just convert to MPFI and i think your all set. Oh, and you have to do some wiring on the harness i think. too early for me to think

Beat you to the punch by a fraction of a second! :P

ill have the si engine wire harness, so i shouldnt have to convert it to mpfi...ill have the resistor box as well........

the main plugs are different. it will be easier to just modify the DX/LX harness. then you will still have to run wires from the ECU to the engine bay.

there is no way around it.
