hi guys i know this question has been asked alot but what ecu would i need? i have also been told if i use a jdm ecu i would have to put a wire in for a knock sensor can any one help me on this? thanks phil
Your going to be using a EK4 loom which will have wiring for knock sensor anyway so that's not a problem. You will want to get a ecu from jap import EK4 as they don't contain a immobiliser like the UK version does.
No once you get the correct engine loom it will connect with your dash loom(green plug) If your EJ9 is prefacelift 96-98 then you need a obd2a vtec engine loom or if facelift model 99-00 you need obd2b vtec engine loom
