I like all the input I'm getting about the options to custom Flash a LS3 / 4L80E. Looking into the future, others might have a need for the same Flash. Posting the Pro's and Con's of the different...

Attached are the 2009 C2500 .bin files (converted from .cal link previously posted above) I think I will modify for the LS3 / 4L80E engine and trans project.

I'm able to open the E38.bin file with...

I've been asked to help with a LS3 engine / 4L80E trans swap into a daily driver.
