silveradoman4 01-12-2009, 12:59 PM Still relativley new to the Quad Stealth II and was wondering when these new updates come out do I need to set my truck back to stock and remove all tuning and then download the updates. I have an 07.5 LMM with DPF removed. Thanks Luckilance 01-12-2009, 02:33 PM yes, using your quad re-install stock settings. (Do not start your truck after installing stock tune or you will throw codes). Then take your quad to your computer and install new software. Then install it on your truck, simple as that. You want to re-install stock tuning before you update software that way the new software saves your stock setting correctly the next time you install. silveradoman4 01-12-2009, 03:39 PM yes, using your quad re-install stock settings.

That's what I figured.....another question, what happens if you somehow break the quad or it quits working and you lose your stock tune. Anyone ever have this happen?? Where could you get another stock tune?? 08DuramaxBoy 01-12-2009, 09:03 PM That's what I figured.....another question, what happens if you somehow break the quad or it quits working and you lose your stock tune.

You would have take it in to dealer for a reflash on the ecm then go again. silveradoman4 01-13-2009, 09:33 AM You would be SOL my friend.lol.j/k.

Luckilance 01-13-2009, 03:06 PM The first time i updated my quad i didn't save the stock setting. My dealer reflashed it for me for free. They also wanted to check out my exhuast. They're cool with everything! cujo489 01-13-2009, 03:14 PM ok, i updated my quad a week or so ago with the new 2.43 version. i did not set the truck back to stock first. i just updated the unit then reflashed the truck to the 90 tune again. how bad did i screw up? cujo489 01-13-2009, 03:45 PM oh yeah, the truck runs fine. sames as before. did i lose my stock tune? qzilla 01-14-2009, 02:45 PM It all depends on what all you updated. If you just updated the firmware to version 2.43 then you are fine. cujo489 01-14-2009, 03:56 PM thanks. thats all i did. Tucker dog 01-14-2009, 05:09 PM It all depends on what all you updated. If you just updated the firmware to version 2.43 then you are fine. Is there any issues with the 2.43? I'm getting a p1448 code, DPF related. silveradoman4 06-09-2009, 11:57 AM Bringing this back up, any issues with the 2.43??? GB87 06-09-2009, 02:05 PM Ive been running 2.43 since mid january and havent had a single problem! Greg_77 06-15-2009, 02:06 PM i've been running mine for a few months now no problems i'm loving my truck without the dpf more performance and better mileage | ||
