Curious if anyone has run across this issue. On Sunday, I loaded new Bama tunes on my car. Hit the key and it wouldn't start. Had this happen before, so I swapped out the tunes in the device, and loaded the old tune back on my car. Received a new set on Monday. Loaded the tune on the car, and the car started. Drove down the street and threw a code. P1639 (Vehicle ID Block corrupted, not programmed). Called Bama and was told this was an SCT issue. I got home and tried to swap the tune, to see if maybe the one tune had an issue. That's where my problems really started. The tuner wouldn't upload or download. Received code 1027 on the tuner, not compatible. Worked through the issue Monday night with SCT, and got the SCT tuner to download/upload tunes. Took it out for a drive, again, threw P1639 (Vehicle ID Block corrupted, not programmed). Tried to swap tune, and it won't allow me. Same problem, 1027 incompatible. So called SCT last night and went through the same process. Put an older tune on that was working prior to the problems, and well you guessed, same problem. If I check vehicle info through SCT device, the VIN is blank. Just prior to my problems, the device did a firmware update, and it is newer than the number on the SCT website. Any ideas? I will again give SCT a ring this morning? The car drives fine, doesn't seem to be any problems, just the check engine
light is on, and P1639 (Vehicle ID Block corrupted, not programmed).
