A friend of mine is putting an H22a4 motor into his hatch, my question is, what kind of ECU could he use? I know all 5th Gen. Preludes have the imobilzer system, so could he use that ECU, or is there another one that would be better?

 

You probobly already know this..He would most likely use OBDII. But, you can get a harness made, or buy the skunk 2 OBDI conversion.

as far as power/tuning capability..Im not sure what is best, but I would lean towards OBDI for obvious reasons.

This donor motor isn't an SH right?

 

The motor came out of a 2001 Base Prelude. It only has about 9K miles on it, so he got lucky when he bought this motor. I was kind of thinking he should do an OBD I swap. I've never done the swap, so what parts would be needed? I know you need the engine harness and OBD I ecu, is there anything else needed?
