Once I set the speed, it wouldn't accelerate, it'd just slow down till some service alarm came up. I put the bs back to setting 6 this morning and cruise control is working again.
From one of the threads in the Cayenne forum, if you are having faulty signals, gnat suggested removing the unit and running the SUV without it for a few days to see how it is doing.

There is also another forum called VW TDI forum, Audi, Porsche, and Chevy Cruze diesel forum. Although mainly a VW TDI site, it provides lots of info. about current turbo diesel technology.

Have fun!

Re: For those who are thinking about Bluespark...

There will be many tuners out there that will have some great tunes to select from. Many are flash tunes. BS seems like it is leading the group and is like Split Second and not flashing the DME.
I am planning to wait until Cobb has a unit and use theirs. I have experience with their tune which is a flash tune but in the mean time (most likely over a year before they have something) looking forward to BS updates...
Oh as an aside I ran a SCMT for 10 years in my Super Duty Diesel and make a significant difference in both fuel economy and power output. Boost max in a mid level setting was 28 psi...
Not even close to as modern as this VM engine is...

Re: For those who are thinking about Bluespark...

While this sounded interesting, I'll be staying away from any and all engine tuning, especially after reading the Diesel supplement manual. I am coming from a 2010 Audi S4, a notoriously awesome car to tune (333HP stock, 400ish with a tune and pulley swap).

It's a constant cat and mouse game between the tuners and Audi NA, plenty of people have been screwed over on $10k transmissions, and god forbid you blow an engine you're looking at $30k. That's one of the main reasons I'm trading my old car in. I've got her tuned now, but I just don't have the stomach for the potential of a tranny or engine failure. Based on the supplement from Jeep, they are taking it one step further by using a black box to capture actual performance runtime data. With the Audi I could flash back to stock and I was good, it looks like with the Jeep they'll know if you ever tuned, even if you remove the piggyback device. You can count on them using that as an out to deny warranty claims should something go wrong (even if it wasn't related to the tune).

"NOTE: Some aftermarket products may cause severe
engine/transmission and/or exhaust system damage.
Your vehicle’s Powertrain Control Systems can detect
and store information about vehicle modifications that
increase horsepower and torque output such as whether
or not performance-enhancing powertrain components,
commonly referred to as downloaders, power boxes, or
performance chips have been used.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed. This
information can be retrieved by Chrysler Group LLC, and
service and repair facilities, when servicing your vehicle.
This information may be used to determine if repair will be
covered by New Vehicle Limited Warranty.
There is a probability that the use of a “performance chip”
will prohibit the engine from starting. In this instance, the
vehicle will need to be serviced by a authorized dealer in
order to return the vehicle to it’s factory settings."

Re: For those who are thinking about Bluespark...

Laugh, that is a standard cut and paste blurb (or very similar) put into every vehicles owners manuals. Doesn't mean its actually happening. An "idle" threat, pun intended.

I don't think either of us is qualified to certify it as idle or not. Fact of the matter is that car manufacturers have been cracking down on these sorts of things of late, and now they have the technology to properly document whether our cars have been modified previously or not. I can tell you personally that Audi has been actively denying warranty claims and they do not even have the ability to detect engine tunes which have been flashed back to stock (if they catch you actively tuned once, your car is flagged in their system and your powertain warranty is pretty much void).

Why wouldn't Chrysler save themselves the expense of a warranty claim if they had the chance? They are not a charity, they are a business. In the end, everyone needs to decide for themselves whether it's worth the risk or not. For me personally, the risk vs reward is just not there.

Re: For those who are thinking about Bluespark...

This is not a new map put into the ECU. That CAN be detected. This is all downstream hardware signal altering. It is impossible for the stock ECU to know about the Bluespark.

Unless peak horsepower, torque or other variables are logged and stored for later retrieval as noted below...

Re: For those who are thinking about Bluespark...

They aren't going to put power meters into every transmission. You know how much that would cost?

Anyways, I hate leaving performance on the table (the engines are detuned for emissions). That blurb sole purpose is designed to scare people away is all, not me though.

Without knowing the internal workings of the computer, I think it's a stretch to make assumptions like this. I have no doubt there are ways to catch data which falls outside of normal parameters, and indicates modifications were made. They don't have to detect the device itself, but the effect it has on the engine/transmission.

Believe what you will, but as was said, it comes down to a risk benefit equation.

Re: For those who are thinking about Bluespark...

OK, I'm going to go against the grain here. If you put a tune on any vehicle under warranty, you are legally throwing away the powertrain warranty then and there. The manufacturer engineers components to withstand x-amount of force (torque/horsepower) - and will tune the engine to produce x-amount minus a safety margin to ensure the drivetrain will last at least through the warranty period under normal use.

To break something with a tune, and then remove the tune to try and get a warranty claim approved is akin to fraud. Plain and simple.

Now on the flip side, if a dealer tries to deny warranty on your sunroof (for example) because of the tune, you have a case on your hands. They cannot wholesale void the warranty based on a tune. The onus is on the dealership and manufacturer to prove that modification A caused failure B. It's in the Magnuson-Moss warranty act (of 1975).

Long story short, if you smoke your transmission with a tune that bumps torque output up to 550, you have nobody to blame but yourself. OEMs have very good reason to take the measures they do by installing "gotchas" in their code so that they can tell if a tune was ever installed. Simply put, they can't trust consumers because too many try to put the car back to stock and cry for warranty coverage after their mods cause failures.

Look's like the scare tactic is working on you guys. No worries, just don't buy a chip.

Don't get me wrong, I'll mod. But cliche as it sounds, if you're gonna play, be ready to pay.

I'll fight tooth and nail for a warranty claim if it's something that broke NOT because of my mods (i.e. electronics). I'm just against the idea of de-modding a car to take it in for warranty work for fear of something not being covered.

I don't add serious power mods until I'm out of warranty anyway. By then, parts are more available, aftermarket alternatives are out, and I know what I should expect to break first because the early adopters have already done the testing for me.
