    Start by trying IBPW1/2 and INJDC1/2... those may or may not work for E78.

    For E38 there is a set of pids named E38.xxxx (same with E67), I'll have to look at which ones are the correct ones...

    in the meantime, can you find which injector pulsewidth pid gives sane values (e.g. 2ms at idle and under 20ms at 6000 rpm).

    The pids for pulse width are GM.INJPWb1 and GM.INJPWB2
