This came out in some 1997 351w SD48B trucks.

Doing some more SD4x comparison stuff.

If you have great, and thanks in advance.

GGB0 is the ALT0 cal cut down from the 460 for the 351.

They are both LHBL0 or some variant.

enjoy

Cool, thank you.
I’m sure you know, all SD4x follow the lhbh1 document pretty much to a T.

Wanting ggb0 because it I think is the newest callbration 1997 code. Just finding the little tweaks that were changed by Henry.

@decipha Do you happen to have an image of the GGB0 circuit board, component side?

no
