Q: what ecu do i need what wire conversion do i need, or instead of ecu swap what vtec controller can i use with my stock obd0 ecu, i would rather go with a vtec controller since its cheaper, and pretty much plug in ang go,even though i know for best results ecu swap is the way to go, i just want my shit on the road Actully i found the vtec controllers on ebay for cheaper than the ecu are Do i want the pr3 obd0 ecu or the obd1 OK SO THIS IS WHAT I RESEARCHED TODAY AND I WOULD LIKE TO KNOW IF THIS IS CORRECT....... iM GOING TO NEED THE PR3 VTEC OBD0 AND THAT IF YOU HAVE BLACK AND YELLOW ECU WIRES YOU NEED OBD0 AND IF THERE GREY YOU NEED TO CONVERT TO OBD1, MINE ARE BLACK AND YELLOW... THEN ALSO FOR THE GREEN VTEC SPOOL WIRE IT NEEDS TO BE RAN TO CONECTOR A AND RAN TO A8 ON ECU WIRE HARNESS THEN THE VTEC PRESSURE WIRES THE BLACK AND BLUE WIRES NEED TO BE RAN TO CONECTOR B AT B5 IS THIS DATA CORRECT?
A: an ecu will actually be cheaper and is better in all ways. an ecu is wayyyyy more plug and play than a vtec controller. you need a pr3 ecu. they can be found for 100bucks. only wiring you will need is 2 wires for vtec, they run from your ecu through the firewall to the vtec solenoid.
