Hey all, what's up? My name's Mark, and I am a new CRX owner. I am currently in the final stages of swapping in the B16A SiR motor. All I need is a PR3 ECU to replace the P28 I have right now. Unless anyone knows of another ECU that will work. Anyways, good to be back in the Honda community again, although I'm new to CRX's, I've had a couple other honda's before, so it's good to be back.
