Hi guys,
No one seems to bring up this subject, offering warranty by the aftermarket tuning companies for modification parts put on the car including ECU software upgrade.

The only aftermarket tuning company that ever offered a warranty backing up the car's modification including ECU software upgrade was a BMW American tuner company known as DINAN.
This company offered bumper to bumper warranty for the modifications added to the BMW sports car, mainly ///M motorsports cars by BMW.

Our Jaguar F-Type sports cars are expensive including maintenance and repair. God forbid after you modify your car jacking up the horsepower, if anything goes south you're on your own. So for me it doesn't matter which aftermarket company keeps telling you it's okay it's okay everything will be okay The engine can handle it The transmission can handle it It's all good. If things blow up figuratively and literally, is it tuning company going to back up and warranty there product or do they simply walk away from the problem. The answer is no, your on your own. It's something to think about seriously.

 

Keep reading we have seen almost zero problems because of tuning and after market parts. Stick with the well known tuners too. I like and use VAP. 5+ years with a tune and pulley and it's still a great set of mods!

Maybe you can post a link to a thread where this happened?

I'm sorry but where in the body of my message does it say or indicate that something happened? I never said something happened. Once again, what I'm saying is, one has to consider, if my engine or transmission goes kaboom... can I afford to spend the necessary money to rebuild the engine. If the answer is yes and you want to roll the dice, then go for it by all means. But if you're dealing with scared money, then gambling with an expensive car in my opinion is not such a smart move. Doing an ECU tune and a pulley add-on is not something that would be considered bulls to the walls modification. After all, Jaguar jacked up the horsepower on this engine to 600 horsepower. Having your car's engine in the range of 600 horsepower I think would be safe. Going beyond that, you're rolling the dice in my opinion. And if the aftermarket tuner company is so spot on and reputable and reliable, then why not offer a warranty and back up what you're claiming and offering. Dinan BMW tuner put their money where their mouth is. No one else seems to dare do this. Just saying.

 

The same applies to just driving it 100% stock. Anything mechanical can and will break.

 

​​​​​​

The stock engine with everything OEM does not have added stress to the original design.
When you jack up the horsepower, the components are all stressed out beyond the OEM configuration. Fact.

 

Nearly all the failures I have had over many years and many cars have occurred after the warranty period expired. In 50 years, 25 vehicles, and hundreds of thousands of miles, I think I've had two warranty repairs. Sure, mods will sometimes void your warranty but the vast majority of people driving today don't have warranty coverage anyway and we all still drive.

 

Yet, stock cars still break.

 

So when you modify the car engine internals and transmission the odds of problems and breakdown increase. You don't drive the F-Type in Grandpa mode. Most people are pretty sporty aggressive when driving a stock f-type sports car. When you modify the car you're not going to drive the car gingerly cautiously but instead you're going to go hardcore because the car is modified and you want it feel it experience it drive it and enjoy it to see what the performance gains are, thus the likelihood of something happening is a lot higher than if it was in the stock configuration.

 

This has come up before, although not recently because nothing new has come up to add to the conversation.

Too risky to modify? Don't.
Want to modify and are willing to accept the risk? Choose your vendor and modifications carefully.
In either case, show some common sense and mechanical sympathy for your car. Things can always break, but part of that equation is the driver. Modifying for more power does not automatically mean you'll be using all of it all the time.

 

This is assuming that the F-Type failures are from driving habits. The bulk of the issues I see have nothing to do with driving behaviors. Coolant pipe failures, neglected supercharger couplers, worn bushings, etc. Having a tune doesn't make the crappy fomoco plastic fail faster.

 

Again where are all these problems from tuning coming from?
This is the second time I ask you to document engine damages because of modifications?

I drive my modified cars HARD! Mine has been to 174 mph documented at the Texas mile. Perhaps this should have caused extensive damage?

Cars are ruined by lack of maintenance and not fixing problems as they occur. They do NOT fail because of modifications!

I clicked on this post with high expectations that it would be information on an actual warranty company as I am debating a tune but alas it was just a random post out of nowhere for no apparent reason. The R-Dynamic is just a detuned R so I can't see how tuning it would cause any extra stress.

 

**Maybe no one brings it up because it hasn't happened. [Knocking on wood for whoever this applies to]. This kinda of info should be relatively easy to find if it occurred.

 

Many have done so. It is extra stress, but within the design capabilities of the drivetrain and within what the factory delivers in other trims. Is the sky falling? Perhaps, but not because of a tune; there's plenty else to worry about if you're so inclined.
