The program JetChips sold at one time was called Jet DDST. I am not sure if that is the same program they have listed currently under Dynamic Spectrum Tuning (DST) or not. Currently Jet has 3 versions of DST. It looks like #14005 is for Gas Class II, #14007 is for Gas CAN ECM's and #14006 is the Diesel program. This fits 2001 to 2005 LB7 & LLY. In the conversations I had with Lyndon he told me that the DDST program was his. I may have misunderstood him and it is possible that he just built the VDF's. Lyndon posted on Mondax that he never got a dime from JET.
I am saying that Jet never paid Lyndon, because Lyndon's software is built by C.A.T.S. and Jet had purchased the OBDII tuner.
Jet could never ever sell the 6.5L legally in the US. I am under the impression that it comes down to the ability to read out the PCM. Most of the non supported GM PCM's/ECM's have the memory broken apart and stored on different chips. You would need to be able to read the calibration out correctly from all of the chips. I am under the impression the 6.5L can not be readout with a cable. The PCM/ECM need to be disassembled.
OK thanks AJ. I always thought Lyndon built the 6.5 tuner so that it couldnt read ECM's on purpose, so as to prevent people form copying diesel shops calibrations. But that doesnt seem to be the way things are. Thanks

Some PCM's can not be read. Most of the Northstar PCM's, Saturn PCM's, 6.5L, and a few others. The 96 to 99 Northstar PCM's I feel could be read out, but sense part of the flash is on the CPU chip and 2 PLCC32 chips, It also has 2 CPU's and it would take a lot to get it out correctly. The 2000 to 2005 Northstar PCM are not a Delco/Delphi and that do not use Motorola CPU's. From my understanding the AVT cable will not read them for that reason. The old 1998 LS1 uses a PSOP44 like the 1999+ do, but the flash is partially flashed on the CPU. You know how those PCM's like to brick, so you could double that with the old Northstar's. I have software that will tune the old Northstar PCM's, but getting the flash to tune is tricky. You can not acquire them from legally from GM's TIS. I am not sure if the newer LML Duramax ECM's can be read without opening them up and modifying the board or not.
My understanding of the 6.5L is that TC can not read the ECM because it is not readable. I am sure if you pull it apart you can read the memory out. You could also acquire it illegally from TIS as I would assume has been done
The 6.5 pcm is not flash capable. Calibration changes require burning a new chip.
