Plenty can go wrong with a second hand ECU. Burnt out injector drivers, ECU being relied upon to drive the coils, poorly wired GPO’s etc etc.
I’m not sure how much you have invested in your motor but have a think abut this.
Your ECU is the thing controlling the fuel delivery to your engine. Would you trust a second hand part to do that job?

Who is going to tune the car for you? Go and talk to them, see what they like to deal / work with the most. If your guy is a dyed in the wool Motec guy and you turn up with a Haltech Elite 2500 he will turn his nose up at it even though the Elite is of comparable quality power to any Motec ECU. People just like certain platforms more that others.


I subscribe to the old adage of “Wolf,guaranteed to start 3rd time every time” lol.
