ABS

hi, i have recently installed the predator on my 07' duramax and worked great, but until recently the "ABS" and "Brake" lights are coming on when the truck is programmed. I have only used the 85 hp setting and adjusted the speedo and mph parameters. What do you think is causing this? It never did it the first couple of weeks i had it on, but there has been two updates since i bought the programmer. The warning lights wont come on if it is in the stock setting. Can yall shed some light on this? Thanks in advance.

What revision is on this tool?
The latest revisions have fixed this issue, and all 07 trucks should be running the latest revision.

Thanks

the latest revision i have would be the r20. Just downloaded it last week. Should i dowload it again?

so....what do you suggest i do?

You are not dialing in the correct tire size if the lights keep coming on.
Try altering the aspect ratio parameter in small increments to get the height of the tire where the ABS computer is happy.

Thanks
