Thread: bank 1 bank 2 injector pulse widths (IPW) different at wot

    bank 1 bank 2 injector pulse widths (IPW) different at wot

    this is 01 van ecu with enhanced sd and live tuning patches.

    for some reason, the two banks are not in sync. you can see, scrolling slowly, the IPW will changes as much as a millisecond between the two banks.

    and overlaying a bank 1 dyno run with a bank 2 dyno run shows it is happening, not just showing up in the data log.

    any ideas as to why?
