Ok heres my deal.....I just swapped in a d15b vtec engine in my crx dx '90. I need to buy an ECU now (pr3) but should I get one that is already mugen or spoon chipped then get a Vtec controller oooooor get a virgin ECU and run the apexi vafc off it. Also does any one know a site that has the specs of the pr3 ecu, vtec engagment etc... Thanks a bunch.
