Table for Alternator Control

[minytrker]

In several LS3 engine swaps I have had to use a license in HPT just to turn on the alternator. How hard is it for EFI Live to add that to E38's?

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.

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.

You will need to use another software in order to adjust it, efi doesnt have the table.

I have TC and it gives me these options. Do I simply want to disable them?



(Well the pic was right side up on my device...sorry)

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.
