Hmmmm brilliant
That ECU is just like a black box u cant do anything with it.
My dear when u build something u learn a lot so its better to learn black box hidden technology instead of purchasing black box.
With self made ECU u can play with it by burning different maps or set of non linear equations etc. even one can do Phd in Engine Controls by implementing Model-Based Engine controls or advanced sliding mode controllers etc.
Btw i am not selling anything over here just sharing my DIY hobby/Research project with PW ECU lovers.
