just got my new quad and the thing sets off abs codes and service brake system codes and makes the brakes act like your trying to stop on ice and the speedo wont work there gonna get me a new model what could be wrong i tried the tire and gear sizing, no effect and it wont even load a tune on an 02 duramax:wtf1:

Did you get the 10-tune version? What is the "new model" they are gonna get?

Works fine on our 2002. No problems whatsoever. Will also run flawlessly with the juice on 5.

It's odd how different trucks can experience different problems. I know a lot of guys experienced problems with the old versions, and some can only run up to a certain power level on the juice.

Good luck with it

Reload the stock tune and try again. I once answered wrong on the Gear Ratio step and it screwed up things bigtime. ABS lights went off, speedo was wacked and it drove like crap, but it was my fault, I hit yes on the ratio when I wanted to change the tire size and boy what a mess.
It should run great on an 02 LB7. Give it a try.

That sound just like what the Predator did with my truck. I had to mess with tire size before it would get close to working right.

But the Quad 4.02 works great on my truck. Not a single glitch of any kind.

You are being punished by the Diesel Gods for telling me you were going to buy mine and then flaking out, not returning PM's and such. All you had to do was let me know you changed your mind. I have been holding my Quad for you this whole time. Mine works great and could have been yours for $500:joke: just got my new quad and the thing sets off abs codes and service brake system codes and makes the brakes act like your trying to stop on ice and the speedo wont work there gonna get me a new model what could be wrong i tried the tire and gear sizing, no effect and it wont even load a tune on an 02 duramax:wtf1:

Mine worked with no issues. Had a ck eng light on one day but fixed itself the next morning.:ro)

Hate when that happens.

ive tried just skipping the tire size, axle ratio same thing, i tried entering the correct info same thing, i dont know but i guess ill try a different one. sorry about the confusion max payne i forgot totally about getting one from you. IM GONNA MESS WITH IT A LITTLE MORE BEFOR I GIVE UP, AND ALSO HOW LONG DOES IT USUALLY TAKE FOR THE FIRST TIME TO LOAD A TUNE I WAS HOPING TO PULL WITH TONIGHT BUT IT DONT LOOK PROMISING

The first time you load it (from stock it takes more time because it has to download the whole stock programing first. After that, it will only upload the modifications to your truck wich is a much faster process, less than 2-3 mins by Tune. I have the 10 tunes v 4.0.2 and it works very well so far.

Is this the one that was just sent in for a 10 tune upgrade?

Sounds like you changed your gear ratio, did you try bringing it back to stock and then try it again?

No problems here so far with my Quad 10 tune. Hope you get it figured out quick so you can enjoy all that new found power.

no problems from mine either from john kennedy. quad and dual lift pumps makes for go fast duramax low 13's all night long.

ive tried not messing with anything except putting the tune on, same thing, ive tried to put the right gear ratio in and correct tire size, and nothing same thing. ive already got it on the way back to quad im really anxious to get it on there and running maybe the second time will be a charm. and also when you first go into the tire selection and gear ratio what is the ratio give, and the tire size given
