LBZ: stock LBZ cab and chassis tune?

[THEFERMANATOR]

Does anybody out there have an LBZ tune from a cab and chassis model with factory dual tanks? I'm helping somebody else out with the DURABURB conversion he built, and he is wanting to make teh fuel system in it work like stock where the ECM turns the lift pump for the rear tank off and on to transfer fuel from the rear tank to the front one. I know about the tables for the secondary sender and all, but figure I will need an OS setup for the transfer pump to make it engage it properly.

Anybody have one or know of one they could read for me? I did a segement swap with a MD OS, but it doesn't seem to be triggerring the transfer pump correctly.

I was able to get it to work with the custom OS that I did a segment swap from a MD OS to a pick-up OS for the fuel system. Once we got the wiring straightened out it works just like it should now and triggers the transfer pump like it should via the ECM.
