And again, without specific wiring info and sensor info....you're still shooting in the dark.

All of these ecu's have fully configurable inputs and outputs, so anyone could wire them almost any way. Hence specifics would need to be given in full, and 100% correct. So yes channel assignment isnt....shouldnt be a problem if you've wired it correctly..but it needs to be known in order to build a calibration that may work.

But you're then asking someone to build you a custom map, which takes time and experience...for free. That's a big ask, and not quite the same as a generic base map for an already known fixed wiring setup and sensor pack etc.

nevermind the fact it's for 3 different ecus lol.
