2007 nbs chevy 1500 5.3 87tune brake light and abs light

I bought the Diablo sport predator and received it today. I installed the 87 octane tune and did not modify it at all. Everything went well but then I got approx 2 miles and the brake light along with the ABS light came on. If I shut the truck off and let it sit for a couple hours the lights go out but come right back on 2 miles into the next trip.. I see multiple people are having issue with this when they change tire size. I did not attempt to change the tire size or the speed limiter on the initial tune. I have since removed the speed limiter on the 87 octane and it worked, but the lights still come on. I can't upload a tune to the internet because I didnt get the cable with my tuner. If the version I have isnt the most current I am going to contact the dealer that sold it to me. All I wanted this tune for is removing the speed limiter to pass tundras so any ideas let me know.... other wise its going to get a terrible review and I will return it...... because it just isnt what i claims to be in the aspect of causing new issues....

Thanks for any ideas

Going through the same problem with my 2007 rado. Tried chaging tire sizes, speed limiter etc. still lights come on. I've orderd the cables to send info to diablo for a tune fix. You can however modify the factory tune to turn off the dod and not get any lights coming on. It makes the truck "feel better" and I don't seem yet to suffered any gas mileage loss, plus keeping all 8 fireing will eliminate the oil consumption problems you're going to have sooner if not later. I think if I can get the 87 tune worked out, with the dod off, I;ll actually get better mileage. Get the cables so the guys can help you. Just my thoughts.

woohoo!!

Thatd be great to have it off, and I hope the upgrade works. Is the upgrade free if I buy the cables? and how much are the cables?

[mikel]

yes, updates are free, cables can be found at walmart, radio shack, ebay, etc.

power adapter needs to be a 12v, 1amp power supply, with the center of the tip positive.. take the predator with you so you can make sure the tip is the correct size to fit into it...

then get a usb/serial cable and you're good to go...

Here is the fix!
