What do I need to change if I wanna change my ECU

Welcome- the better question is what do you hope to accomplish by changing the ECM? The answers will vary depending on whether it's a repair or a hopeful upgrade?

It'll also help to post what year and model of Z you own, as well as overall mileage and mods.
