Going back to oem ECU but from a different car questions

[Jammygit]

So currently i have an Apexi power FC ECU fitted in my S15, i bought it like this so i don't have the original ECU for the car. My question is if i wanted to return to an oem ECU would one from another car work okay or would it need pairing to the car etc. I'm a bit unsure when it comes to the ecu/immobiliser side of things and what will or will not work.

And if the answer is yes another ecu would work then is anybody interested in a px of their oem ecu for my power FC ?

if your car is a JDM import then get a JDM one, manual to auto might make a difference due to different injectors, there is bound to be someone on here in the UK that will have a stock ECU for you

Stock S15 JDM ECU will fit and work on any other S15
