Any good pids for fuel useage?

[pavetim]

Don't need a mileage one I was just wondering if anybody had a PID for average fuel useage so I could set my cruise at 75 log fuel to get the average mm3, then make a change and do the same thing to see if it effected fuel useage? Thanks.

I have seen a calculated PID somewhere. Not sure if here, Diesel Place forum, but feel you may get some help here. http://www.msdignition.com/forum/forumdisplay.php?f=24 Search for say duramax mileage there. Not EFILive but may find the PIDs they used to calculate. But when helping out there they never got the LMM right. LBZ was close. Using the same PIDs on the lmm made things backwards. Not sure if they actually ever got a right mix to work out. When they kill the ken Mosher team the product support went bye bye.
