I have no freakin clue what Celly's post above means, but I just hope he is working for NORAD.

I thought he was talking about a quad???

Why do the manufacturers make it so difficult? I would think that making cars easier to "mod" would make more people want them, which would increase sales, which would make them more money.

Because then people who dont know what they are doing try to mod them too aggressively and blow the motors up and then place a warranty claim which costs the manufacurer money.

Agree with moosehead, thanks Celly.

What he is saying is mostly over my head too BUT I do understand what he is saying about cloud-mini super computer-breaking encryption. It seems the tuner companies shud be up on this but as usual the easy $ route rules. Hypertech is already bragging on stuff for 2012 Chevys.
Also agree with Mr. rednecktruck. If too many warranty claims, why r Fords and Chevys so comparatively easy?

more warranty work = keeping union workers employed

Re: Any new Updates heard for a WK2 Programmer - BullyDog, HyperTech, SuperChip

Again, not a computer expert, so while you seem educated and well-spoken on the subject, its moot until someone "cracks the code".

Until someone does crack the code, it is unhackable.

Apparently if you swap in a 2010 PCM, and do some voodoo to it to prevent it from going into limp mode, 2011's can be tuned....

Also, With Brute force, a key is mathematically only as strong as %50 of the available keys. Since the key could be the first key tested, or the last key. The average comes to %50. (This is an uber basic explanation.) So when someone says "There are Eleventy Bajillion possible keys..." you statistically will only need to test what ever half of Eleventy Bajillion is.

I'm not saying this is easy, but 'Unhackable' is not true.

Either way, I doubt these companies use brute force. My Guess is they look for weaknesses in storing or maintaining of the keys. Ie. The plain text version of the key is kept in memory, or they notice that when a flash is requested that x changes to y, and find the cause of why that happens -- or what changes where -- to know what needs to be overwritten.

Or, They just keep calling their insiders at the manufactures that they get Drunk and Laid at SEMA until they give details on the ECU's.



Ha. I live down the street from Superchips, and Even have a Hemi Wk2. Perhaps I'll send them a resume. lol!

if its as easy as you say it is, then 128bit encryption would be useless, and yet the majority of "secure" sites use it. I can't gather whether or not you're here to help, and if so, go ahead and setup this brute force decryption key and setup a successful business where we will gladly hand over our cash for you to tune or vehicles. Your post had no helpful information in it whatsoever except spouting techy keywords and showing how much internet reading you've done.

Re: Any new Updates heard for a WK2 Programmer - BullyDog, HyperTech, SuperChip

Im sorry to be a negative nancy in this thread, but I am a realist. I know this will take some time, so I am waiting patiently and not getting overly excited. Im sure there is more than one Armchair Programmer reading this thread, but until the day we have tuning support, it is all vaporware and hype.

Average drivers around here do 80-85 mph on the highway, trailer, boat whatever.

Police, speed cameras, not worth loosing a licence over.
already lost points towing 110km/h in a 110km/h zone.
10km over the legal trailer towing limit of 100km/h.
