Programmer and warrety

[lithium1189]

My cousin has a 2009 6.4 and has the extended warranty. Would a programmer be detectable if ever he needs to bring it in to be fixed?

some dealers are good and some arent, usually if you get a good tuner like spartan or h and s and return it to stock, they dont break your balls unless its somthing serious

i could be wrong but here is what i belive. The spartan pulls your whole program ,stores it and dumps thiers in. were the h&s piggy backs the stock program leaving a big footprint and will cause the ford dealer to get a code when they look for it. the spartan is hard to find but if you have a 100k on the truck and it tells the tech it has only started two times in it's life they will know you just dumped the stock program in two starts ago. i had 30k kms on mine when i deleted with spartan and have not tried any warranty stuff yet so i don't know what i can get away with. just return to stock and hope for the best

I think you should always assume that modding the programming of truck will possibly lead to voiding warranty. This is a known risk and something to think about before buying programmer or deleting emissions. Personally I think it really depends on the seriousness of the issue and the dealer you bring truck too for service. Good rule of thumb is always return to stock before attempting any warranty work. Its a pain in the @$$ but worth it to keep from paying for repairs out of pocket.

When you say return to stock, how far do you need to go. Remove the tuner, set back to stock or no power and unplug. What about DPF delete pipe and cat back exhaust? should the stock exhaust be re-installed? Just curious.

You have to reinstall all stock parts (Exhaust and everything). All tuners are detectable, it just depends on how hard they want to look. But for the most part Spartan, SCT, and H&S are fairly hard to detect. Also, I am pretty sure that the dealer can see the last time that the truck went into regen.

Any tampering with emmisions voids the warranty. If you just put a programmer on and something tears up, they have to prove the programmer caused the problem. Ford also probably has a lot more money and better attorneys that you so keep that in mind.
