So, I just got this prelude and I was told it was JDM, and High compression. Can Anyone tell me what ECU is correct with this vin 322A 3042129? The prelude needs an ECU compatible with the motor.

 

I'm assuming you mean that the engine is JDM, not the car. An easy way to find out, is to look at the stamp on the front of the block. The top row will tell you what engine you have; which will tell you what ECU you need.
