Hi guys, I'm after some clarification, I have recently acquired a Mk4 Escort van which has had an EFI XR3i CVH engine installed...basically everything from an XR3i was removed and installed into the van...what I need or want to know is what type of ECU would this have? I'm reading reports of OFAC and OFAB, however, thinking its NA, I thought it would be OFAC, but then I hear of people converting their XR3i's to OFAC...so I'm a bit miffed what actually came on these cars...

Thanks for any help guys...im sure its an obvious answer but I'd like to be sure...as I know I will ultimately be throwing lots of turbo parts at it to liven it up at some point, but wondered if its going to be as simple as I think (rods, pistons, inlet manifold, exhaust manifold, turbo, actuator, pipe work, etc) or is the ECU side going to cause complications

Cheers!
