I have a pretty rough idea how it works, but mainly how do you connect it to your car? Does it replace the factory ecu? How do you wire it in?
Also since i finished my m42 build what are some good ways to tune it, can some one explain what wideband and a smt 6 is? Also how you hook it up to your car thanks! Does this work with you ecu? Doest it replace my afm with a temp sensor?
