Put a 95 B18b into my 90 HF CRX. I used a 91 Teg dizzy, CRX injectors and a PR4 ECU. I am getting a code 1 and 3(O2 and map) I triple checked where I lengthened the map connection and it is good. I get the same codes with two ECU's. Both will crank and run the engine well. Just for ***** and giggles I hooked up the original ECU and it cranked OK and no codes! Any help or sugestions would be appreciated.
TIA
