HPTuners NNBS tire change=brake and ABS light
So, I've been fighting this issue for well over a month. Is anyone else having this problem? If I change the speedo output in my tune for the taller tire, it kicks the ABS light and parking brake light. No matter what values I change (manually and auto calculate from the wizard) it still does it. I just ended up doing the auto scale then changing the speedo output to stock so, I don't have to deal with the annoying ding and dash lights. In turn my speedo is obviously not correct. Wanting to put gears in this thing but, think it's damn ridiculous I can't perform the basic speedo change.

I agree I shouldn't have a problem, hence why I'm asking others if they have had the same issue. What software are you using? If you are willing to help please ask what details you would like, thought I was pretty detailed other than tire size and the truck is a 2007 Silverado? As mentioned earlier, i did it manually as well as with the built in tire/gear wizard that auto scales within HPtuners. Either way, when I change my pcm output calibration aka pulses per mile which corrects the speedo, the codes set.
