predator turning off my ABS system?

[whitneyrd]

2006 Chevy Duramax 2500 4x4. Predator U7186. I do not know what revision it has? Purchased the truck last month from a small dealer. Had the dealer install new tires which were different size from the bald ones they replaced (355/60R/20). On the way home my ABS brake light came on(every time I went over 55mph) so the next day I went to the dealer to have it checked out. They stated that the abs was OK the problem is that the computer thinks that the tires are a different size. Need to program the correct size tires in the computer. Called the dealer that I purchased it from and they said "ooh we forgot to give it to you". Picked it up and went onto your website to get educated on how to use. Installed the 85hp program and modified it with the larger tires. Now the ABS light comes on every time I drive the truck and had to slow down rapidly on the freeway. The back tires locked up (putting a flat spot on my new tires,thank you) and the ABS did not engage. Any suggestions? Rick

what is the revision on the Predator?

How do I find the revision is on my Predator? Went to the dealer today to turn my ABS back on. They were unable because the predator is not loading the program with the tire size into the computer in the truck. Used the instructions to modify the program, but the predator is not loading the program correctly. purchased the cable and power supply today. need to figure out how to download and update Predator(tomorrow).
