sct use

[viper40]

does anyone know if using an sct tuner void the warranty?

[fordfan30]

yes it will.

If you reset back to factory tune is it detectable that a tuner was used?

[FrozenInTime]

Yes, they will know it. It sets a code that cann't be seen or reset by the end user I'm told.

I was running my sct for about 20k miles when my headgaskets blew so i flashed back to stock and drove it a month to six weeks to get a few drive cycles worth of stock tuning before I went to the dealer. I was praying they wouldnt dig to deep looking for an excuse to deny warranty. I was almost surprised when they called and said they had approval to do it under warranty. I gave the tech a hundred to put my studs in instead of bolts and supplied the torque wrench and studs. Did they know? I dont know but i felt like one lucky s o b.

I guess it really depends on the stealership. Some will shaft you when they see it. My local ford stealership mechanics told me they do it all the time, ignore the tune, that is.

You drove 6 weeks with blown heads? I blew a head gasket in my Mustang (RIP) a few years ago on my way to work. Tried to get it to the shop, by the time I made it the thing would barely idle. Mechanic told me I was lucky it didn't hydro-lock on me.

That is the key 100%. That goes for trucks from Ford motorcycles from Harley you name it. There are horror stories for all of them.

Yeah I was on the way to TS in 09 pulling my travel trailer on a tow tune. I just flashed back to stock and took it real easy the rest of the way down and back. The temps stayed fine. I only live about 100 miles from there anyway. But I knew I was gambling doing that.

Technically they have to prove that it caused the failure to deny warranty.
