Not so much hard, it is the time to do it that is always the issue for us. Between the E38 and E67 we support over 100 OS's so rolling it out over all of them isn't a small task. And I can guarantee if we only did it for a handful the next day there would be a request for them to be added in to an OS we didn't do.
I no longer monitor the forum, please either post your question or create a support ticket.
Alternator control no BCM I to need this control
Can someone explain what the BCM is doing that the ECM is not? Ls1b controls it right. Why is it different? I see both alt wires going into the ECM just like the ls1b... sorry, it's confusing to me I'd like to learn more since I am currently doing LS3 swap.
I use hpt for it and adjust the table in the pic in my first post.
BTW: you can do SHFT-PRTSCR to get a screenshot.
Looking at a stock vette LS3 tune in hpt shows alt remote/override settings disabled and not fitted. LS3 Camaro has them both active.
Did the vette not have BCM charging control with current sensor on the negative cable?
Try disabling some of those...
but you would have to provide battery voltage to the alternator F or L input (via a relay activated by key-on... and a fuse ahead of tne relay), I don't remember which input, look at a wiring diagram for reference.
