I tried my predator on the economy/performance setting, everything worked great, I tried it on the exteme setting and everything went awesome. BUT the ABS and brake brake light went on, and then stayed on. They say that the lights are supposed to come on, but go away after 2 minutes or so. but I checked again today, and they are still on. I put the tune back to economy, and no difference. Anyone heard about this before?

 

Gonna have to get a code out of it so you can tell if it is ratio related or an actual ABS problem. Is the predator a downloader? Not up on it much.

 

The Bullydog did that on my 06... Had to call them to do some special triple backflip monkey side grab on the tripledog to get it back to normanl!!

 

they usually clear out after about 4-5 key cycles of starting the truck does it to mine when I change tunes then goes out so don't worry.

 

when I first programmed my truck with the predator I had the same problem,diablo had me return the truck to stock then disconnect both batteries for a few minutes and turn on the headlamps,then after it sits a few min. turn off the headlights and reconnect the batteries and reprogram to which ever tune you want,this worked for me but I did have to drive it a short distance until the lights went off but now when ever I change between tunes the lights go off by the time I get to the end of my driveway.

 

i will try that tomorrow. I went and drove the truck after I put it back to the performance tune, and the lights went out after about a minute. I will try the extreme again tomorrow and see if those tricks fix it. thanks.
