Ive recently converted my Orion running standard 1AFA (same as an XR3i) management to EFi Turbo, OFAC management.

What are the changes nessacery for the wiring/ECU?
I thought it was plug & play, but it seems the CO Pot isn't doing anything and the car isn't returning to "base" CO setting when the CO Pot is unplugged, does the CO Pot (Pin 27 on the OFAC ECU) have a different Pin on the 1AFA ECU? Therefore with the OFAC fitted to my 1AFA wiring the ECU isn't receiving the CO Pot's signal? Or is it more likely a broken wire from the CO Pot to the ECU?

Also does any1 have a wiring/pin out diagram for both 1AFA and OFAC
