Failed to Read PCM

[bchap05]

Hi I've talked to tech support on the phone which didn't help so trying one last time for any other ideas before I sell it and go with another tuner.

2006 Silverado, 5.3. I have pulled the amp fuse, HID fuse, trailer harness, stereo harness, wiper fuse. I have updated the software.

When I go to load a tune it does the key off, key on, then gives me "Failed to read PCM Original Backup, Error Code=0x00000324. I've spent 5 hours pulling fuses and retrying. Nothing works.

Truck could have been tuned by a previous owner? But I don't think so as it won't go above 100 mph

do you have another vehicle you can try it in to see if it works there?

That is what the phone tech suggested. I thought I could use my roomates but he's under warranty and doesn't want me to. I'm 98% sure the tuner works fine. Trying to find a co worker that will let me go out in the parking lot and tune them real quick. But having trouble finding a compatible vehicle

Pulled the Info fuse, both wiper fuses, radio fuse, along with all the others and it finally did a back up and loaded 87 octane tune
