Finally !!!
Some good news.
HP Tuners came over last week. There were a total of 48 fault codes being logged by the BCM. NRE and HP corrected 41 of the 48 so far. They are pretty sure they can get the last 7 figured out this week. But the best news is that with the 41 done so far the car will continue to run (i.e. the alternator charges and doesn't shut off, the basic dash operates and almost all of the alarms aren't yelling) so it is driveable.
Hope the rest get cleared this week. With that we can do the final tranny tune, AMS-1000 Boost Controller maps and then SST can come home. Damn it has been a long 5/6 months since this non-ECM computer 'glitch' reared its ugly head...
