Voiding your warranty.

So if your car is a weekend toy your either good or screwed.

I think the idea was mileage divided by key turns.. lol, but the humor still stands.

The weekend toy might actually get away with it, given the low mileage.

Or......what if you drive long distances frequently? That would also create a low key count but higher than usual mileage.

The thing I find interesting is on page 17. It basically says the only way they can tell the ECU was modified is based on key turns. I had a WRX before this and it was a hotly debated topic, but my research showed that they went off key turns as well.

I have never read here, or anywhere else, of a warranty claim being denied due to a tune. I figure folks return their vehicles to the stock tune before they take it in, like I would do.

If it's key turns, well, Mustangs don't have keys. And my tuner does the whole shebangabang with one press of the Start button, IIRC.

From what I had heard, they're looking for ridiculously unreasonable turns, like say you have 50 or so turns with 25,000 miles. That doesn't really add up.

I've seen a few cases where people got denied due to tunes on WRX forums. The dealership said they knew that the ECU had been modified. Some people flash with a low amount of miles, say like 5k. When they take a backup, the backup also keeps the number of key turns. So then they drive it 20K miles, something blows up, and they restore the ECU backup. The key turns on that backup don't line up with what you should have at 25K miles so it's plainly obvious that the ECU was modified.

The key turns aren't the end all be all. They'll probably use that as additional evidence when they see things like bolts clearly being disturbed, then put all that together to deny the claim based on aftermarket mods.

I don't necessarily mean literal key turns. It's an ignition counter, but you get the idea.

Right....

But I would imagine that someone needs to want to find something to go looking for it. I think it's most important to have a good relationship with your dealership. Be nice to them.
