Hello, i got a 2005 F-250 with a 6.0L diesel and i would like to reset the computer in it if possible. I had a SCT tuner in it and just wondering since i returned the computer to stock and am getting rid of the chip, is there any way of reseting the computer to get a better chance of not leaving a fingerprint of a chip??? I unhooked both batteries both + and - and i will let it set for a couple hours. Anything else to try?? I was told that my tuner would not leave a fingerprint but i just dont want to chance it. Thanks!

 

Unhook both batteries and turn the headlights on. Give it about 5-10 minutes to make sure the capacitors are good & drained. Hook both batteries back-up and your back to default settings until the truck has enough time to re-learn your driving style.

 

Here's how to unhook an hook back up.

ok do you think that after that can they find out there was a chip in it?

 

You don't chip the 6.0L...you "tune it" with software flashes. Now if the truck was tuned...unless you've replaced it with something; I think it will keep that tune even after unhooking the batteries. Not 100% sure since I'm running a stock tuned truck.

 

That depends on who "they" is...I'm pretty sure Ford could find out if they really wanted/needed to.

 

I know with 100% certainty that a Ford dealer can find that information no matter what you do to reset the computer.

 

And if it had a SCT tuner on it he needs to reload the stock program. Disconnecting the battery will not return it to stock. It will only go back to "tuned defaults". Looking at your post again it says you returned it to stock. That is about the best YOU can do. Like stated earlier if they want to look they can find. Wait until insurance companies start LOOKING into our vehicle computers all the time.

 

ok well i will just take my chance. Im looking to trade it in today and so i dont know if they will hook it up tho the computer right away or not???

 

If they are not specifically looking for evidence of a tuner they won't see it.

 

My 06 Ford F-250 will not run right when tach seedometer not working right can you tell me why

 

You would be best served if you create a new posting and include as much detail as you can on what your truck is doing.

 

My 06 Ford F-250 6.0 motor when I start it up the tach not working and speedometer showing 40 mpg and I going faster that pickup has no power and when tach and speedometer are working right pickup runs good

 

You should start a NEW thread with more info. It could be a number of things though. Does you gages, radio and power windows ever stop working while you are driving?
