Its quite possible thats what is going on. All we get is a screen full of ascii at this point. Hence the need for an intrigued supernerd! We cant see anything intelligible - yet.

Most of the Isuzu sensors seem identical to the across the board GM stuff. The Gen IV V8 ECU is crackable/programmable, has a crank angle wheel identical to the Isuzu, but has 4 cam position triggers to the Isuzus one. Thinking of setting up an external drive that will take the V8 cam position wheel and just seeing if we can get it going - but the time for that has to fit in around customers....!
I have seen the 'rogue setting in one box' on GM ECUs too - it does make you wonder.
