Long story really short..
AJPTurbo tunes are about 2 years old. Was running the last rev without issue. reverting stock == no issues...
Tried a GH tune. It applied but that tune file broke the SCT handheld's flash file system.
SCT fixes the SCT handheld with a bunch of SCT device firmware updates to handle newer tune files
Thought everything was ok..
Decided to go back to AJPTrubo tune
Revert to stock - FAILED
--ACC disabled > 'malfunction' on dash
--collision disabled > 'malfunction' on dash
--Running rich by 10% but no codes
--p1000 DTC OBD II Monitor Testing Not Complete
--p1639 DTC Vehicle ID Block Corrupted, Not Programmed
--p163f DTC Transmission ID Block Corrupted, Not Programmed
Called SCT, SCT reports 17 other cases with same/or extremely similar errors .. there is a firmware revision for SCT that may help. we tried .. It did not.
So now im off to get the car flashed by IDS to rewrite the whole unit and cross my fingers.
But after that .. I have a feeling I cannot flash the car any more now that the SCT firmware is modified/updated because any flash back to stock will fail likely again... as a software guy I just cant shake the feeling i'm boned and flashing a tune will be a one way trip.
SCT advised the 2010/2011 Tarsus have a much larger number of flash related issues versus the remaining years.
also of note I have a fellow tuned SHO owner in town who has the EXCAT SAME issues after a GH update.
