#60653 I am planning on doing a OBD1 B18C swap for my 1994 CX, i figured this would be simple enough until i starting looking at EM options. The A'Pexi Power FC looks to be the best balance of utility and price for my eventual goal, however the FC is for the OBD2a DC2. Ive seen some conversion harnesses out there, is this the best route?

OBD1 engine>OBD1 car> harness> OBD2a EMS

Or would using a OBD2a enigine then somehow retrofitting the car's electronics to work with the engine and therefore making the EM swap easier a better way?

#60985 I am a big AEM EMS fan and have heard nothing but bad things about the A'Pexi offerings. With the AEM, you wont have to get a conversion harness. Just buy the application that matches the engine harness in your car. Then load up the base map for the engine and have it tuned.
