Hey guys....lurker/noob here.

I just updated to build 555 to try reading the PCM on my '99 Chevy K1500 Pickup (5.7L Vortec). Once downloaded, it told me the PCM was not recognized and to email it to the support address. I just sent the .tun file out to support, but was wondering if you guys knew what might be wrong. Here is the information I can see in the Tuning tool:

OS: 09365085
Calibration: N/A
OS ID: PB
BCC: N/A

EFILive calibration definition file (*.cal)
Name:09365085.cal
Version: N/A
Date: N/A

Segment ID Checksum
Operating System 09365085 $4DF6
Engine Calibration 9364825 $0473
Transmission Calibration 16232737 $5153
Fuel System 9351030 $6F19
System 9351051 $44C2
Speedometer 16188969 $61C0

That's all I can see.....everything in the calibration tab on the left is un-clickable. I'm a complete beginner on this stuff, and clueless for the most part, but I never had these issues with the GTO.

Anybody have any suggestions? Thanks in advance.
