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

So excited for this tuner!

So along with the potential for increases in Torque and HP, is there a gain in Mileage typical at all?

I know the relationship between the 2 may be inverse, but a gain in both power and mileage would be greatly welcomed

Scott... I'd be interested in more info about possible fuel economy (when not driving like a mad man), custom tune per mods, and pricing. Please keep us up to date.

Manual Control Over the QL

What I want is Manual Control over how and when the Quadra-Lift engages.

Currently I believe the system works like this:

Offroad 2 - 15 Mph
Offroad 1 - 45 Mph
NRH (Normal Ride Height) - Up to 65 Mph
Areo Mode - 65 + Mph


What I'd like to be able to set manually:

Offroad 2 - 45 Mph
Offroad 1 - 65 Mph
NRM - 85 Mph
Areo Mode - 85 + Mph


This way, I could run the vehicle at Offroad 1 height (my preferred height) around town. At freeway speeds (65 up to 85), either NRM or Aero Mode should be selectable. Above 85 Mph, Aero Mode would be required.

I don't have a problem with the ride quality at Offroad 1 (18" tires) and would love to be able to keep it at that level unless I was on the freeway.

Manual Control of the QL would allow people to adjust it the way they want (within reason).

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

I think you guys are over estimating what a Super Chips type of programer will be designed to do.
I would be shocked if any of these tuners include anything beyond engine and transmission performance with a data logging bonus.

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

As with a lot of tuners facing closed loop ECMs does SuperChips have a way to counteract these fuel trims? When in open loop its easy to change a/f ratios, but once the car is warmed up the car goes into o2 feedback mode any sort of changes on the front end will be negated by the o2 sensors on the back end. does superchips adjust the o2 feedback signal to prevent this?

perhaps the long term solution to changing tuning is to look at adjusting the o2 sensor feedback signal instead of adjusting injector pulse. who cares about performance when the car is cold anyways?

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

I know, I am hopeful that something will come out even if it seperate from an engine tuner, to be able to lock the WK2 into certain heights. I don't even care if it doesn't automatically adjust, as long as I could lock it into OR2 or OR1 w/o lowering itself.

someone would need to pull a wiring/ecm diagram for the jeep. if the QL system has a separate ECU that pulls speed data for ride height, then there could be a module created to modify the speed data going into QL. If there is a secondary checksum where the ECU cross checks ride height to vehicle speed, you'd also need to modify the ride height signal going back into the ECU. without seeing a wiring diagram its hard to tell. I'm sure there are a couple of EECS gurus here that could help create such a unit.

Regardless, this is sort of outside the scope of engine tuning. Perhaps a discussion over in suspension would yield better results.

Off topic?

Yeah, can you guys please take this over to the suspension section?
The closest I get to off road is the boat ramp. Sure ride height contributes to aerodynamic drag. That is why I got 4x2. I would have liked full time 4x4 for safety, stability, and traction, but Jeep doesn't offer this simple a system except on the SRT.

ON TOPIC, I want something to cool that lump of metal off, increase its efficiency, and increase its power. Which is why I got the 4x2 with the Hemi and will trade it on an SRT as soon as it gets the 8 speed.

Not everybody goes off road in this vehicle anymore or lives in climates where 4WD is a necessity. I just want a go fast, safe, kiddie "hauler." The heck with QL, where are the programmers?

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

But this isn't a suspension issue it's an ECU issue. A simple flash of those values would change/remove the speed limiters and rectify MANY gripes from owners.

The only issue with the ECU is the encryption after that it's cake. I'm using ECUFlash to completely redefine the how my EVO runs. I think you underestimate how easy this really is.

Ive been in this scene for several years now, and to be blunt i think many underestimate how hard this is. It took over a decade to get the (by now) stone-age JTEC PCMs to be tuned by something other than a mail order flash . It took 3-5 years for Diablo to get any sort of tuning support for these trucks and even then, the support is limited and varies from year to year. HPtuners has been working on Dodge support for almost 4 years if not longer and they still have no ETA.

Im no computer geek but the 2011s and beyond use 128 bit RSA encryption....which in english is regarded as unhackable. If anyone has a background in computer programming or hacking for that matter then I would recommend seeking employment with one of the above tuning companies...If it were easy everyone would be doing it....

This is true and False. If you look at a Brute Force type attack, these times go down every day as processor speeds increase. In fact with cloud based computing, an amateur with a few bucks can spin up a mini super computer on amazon EC2 in a matter of hours. IN FACT you can even now spin up GPU (Video cards) Cloud instances that are Turbo Charged math crackers... Look up Bitcoins to see the performance differences between x86 and GPU type situations. Heck, even PS3 are cracking beasts -- which is why the Airforce has a 'super computer' built with Sony Playstations. And I know of a project using FPGA's to realtime key cracking...

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!
