hi there,

I'm very new to the ecm programming, just trying to get started. very open minded to assistance.

still hoping to get some help with the pin out so I can change my computer over.


Thanks to anyone,

What computer are you switching over to?

If you are switching to an '0411, I've been successful using the 2002 Express Van 5.7 / L31 schematics for the Vortec 7.4 / L29. The 2002 L31 is a decent baseline flash.

I don't know if gearhead-efi member Lextech is still active, maybe send him a Private Message, he might be able to help with the pin outs.
