I am using and tuning a medium duty (J1939 throttle) Allison standalone TCM using V7.5, i can tune it , flash it, scan it and read PID's out in EFI V7.5 no issues.. (my dashboards and data display record and monitor fine in V7.5

In version 8 auto detect doesnt work, but I can manually select the TCM from a list.. I can even load a BBX file from Version 8 to my Flashcan and read the PID's on the Flashscan screen without issues..

However when I try to monitor or record data in Version 8 it says "no controllers found". this TCM is standalone without an ECM attached to it..

is there something in V8 that requires an ECM to be able to read a TCM thats not present in V7? I dont change any hardware.. im always connected to the same CAN pins of the TCM with V7 amd V8..

I'd Like to be able to can it and read PID's in V8 simply because the Dashboard looks like it is nicer in V8 than in V7...

any ideas?
