THS, one reason someone would want a chip is to stop it from shifting fron OD to drive and then right back which mine does if pulling my RV.
The old tired line about negating the warrenty has been hashed and rehashed on a dozen different boards and I've never heard anyone say that the dealer voided the warrenty because of a chip. I know that uncle John works with someone who knows someone who had a chip and the dealer wouldn't replace a battery because of the chip, but no-one that I've ever heard has had a warrenty voided because of it.
I'm not trying to start an arguement, but that has been beat to death. If the dealer wants to void a warrenty they can ask for proof that the service manuel has been followed completly and very few could prove it. Later, Nat
There's no doubt that a chip/programer will be useful in some instances.. As for the "voided" warranty, well it really depends.. It does happen, I have been involved in it happening... The key to the whole process is, did it cause the failure?? There is more to vehicle warranty than just the drivetrain, theres also more to the drivetrain than the engine, trans,and rear end(subsystems).. You could have a chiped truck with 100hp more than stock, take it to the dealer with a leaking water pump and it should be covered.. But if you were to take that same truck to the dealer and a rod was hanging out of the block, your chip will be questioned.. The process becomes more of an investigation at that point. The leagal end gets a bit sticky, and can vary greatly depending on where you live and how the judge looks at the information presented to him(if it goes that far).. If you are the type of person who refuses to take responsibility for his own actions and denies that the chip caused the problem, you may be able to fight it in court and win. If you are a realistic honorable person, when you are told that your chip, that you installed specificly to add more fuel, change the injection timing, create more turbo boost, change shift points, etc.. or that K&N filter you had to have, dusted the engine, you should be inclined to accept the thruth and say "well, ok I guess it really cannot handle that" and go on with paying the bill.. Unfortunatly, our entitlement society creates more people saying "forget the dealer/mfg, I'm not paying for nothing" wich causes higher sales prices in the long run to cover rediculous warranty expences from previous years..
With that being said, I have no problem with a good quality chip/programer, installed by someone experienced with the product and capable of dyno tuning it.. Personally, I like the lower power programers, simply because they get rid of some of the annoying things like poor throttle responce(perceived as turbo lag).. The fuel economy may actually increase due to more efficient fuel timing concerns that the factory was not allowed to used because of some CAFE criteria.. My point it, there is allot more to this topic than just the dealer trying to screw you..
