Not to go OT here, but figured I would clear up some things here.And why cant the Allison talk to the V2? EFILive's been tuning the Allisons for about 5 years now. I cant remember if the latest 6spd is fully supported yet, but it might be by now.
We've heard all Allison 1000s use the same TCM for different applications but are still year-specific. ie a 2006 Allison 1000 6spd uses the same TCM in a Silverado HD as in a motorhome chassis.
Yes the V2 can talk to the ALLISON TCM for any 1000, 2000, or 2400 series TCM up to about 08(5 speed and A40 6 speed TCM's).
Hmmm interesting, didnt know that. I remember a year or two back where everyone was hot and heavy on swapping an Allison behind a Cummins and a company made all the adapters to do it including the TCM.
DESTROKED is the one making the adapters, but they only supported teh 5 speed TCM's. They got PCS to make a program that would allow a PCS fuel box work as an interface box to provide a TPS signal for a stock ALLISON TCM from an 03-04 LB7 GM truck. They still make them, but haven't made a 6 speed set-up yet as the 5 speed TCM used a more generic J1939 protocol whereas the 6 speed TCM's use teh GM CCAN based protocol only. The 6 speed TCM can be made to work though as MAXPF has been playing around with it. If somebody would make a CAN based emulator though, one could swap a 6 speed ALLISON into most anything(or if ALLISON would lift there restrictions off of there programming, one could make a custom OS using the ALLISON DOC program).
Gotta love that, and Truck Source says is a pretty stock truck! It sucks, I really REALLY want a diesel now (Dmax or Cummins) to tune and see these huge gains with. Dang, not in the cards currently.
