Sean, I don't think I would have told that!
Your gonna have them seeing black helicopters

yea, that's one big conspiracy

Sean,
I already knew that!

Ed, you have a right to your opinions just as I have a right to mine.

I never said it could be done by a high school kid. But I can tell you personally that I have worked with a Chrysler engineer in the past and I know how the code can be altered. I was also working with a Cummins engineer when the first wave of 6.7 issues came about. During a test drive with me at the wheel and the engineer typing on his laptop, he uttered the "words hold on tight". The next thing I knew we had the rear tires smoking while on a steady 60 mph cruise.

Code is broken and re-written every day. The aftermarket programmers do it all the time to factory controllers. If you think that someone won't spend the time or money to have this done, that's your right. But with Chrysler having Hill Ascent, Hill Descent, Traction Control, Sway Control, Stability Control, plus countless other factory programmed controller functions designed run the throttle plate as needed (not as driver commanded), I don't believe it would be that hard for someone to alter code or write new code to produce throttle stop effects.

Why don't we just make it manditory for all cars to have a cable or linkage operated throttle plate. Wouldn't that solve your footbrake racers issues??

Having been a computer "geek" for 30 years - no code is unbreakable

Hackers do it everyday for nothing - for the fun of it.

Image what you could pay someone to do.

All you need, is to know what you want them to do and they will figure out how to get the desired results using the sensors to do things they were not originally intended to do.

It is the reason to move to digital technology and get off of 50 old analog "stuff".

The MDS digital 7 allows the old to meet the new in the area of timing. "slurry" can be accomplished in that box with out buying it in the box (MSD model). GPS can be used to control ET in the same NHRA approved box.

Fuel and throttle control need the latest new parts and sensors - hence the reason to have a new car

Do you really believe double 00 lights and dead on double 00s should happen as much as they do? Some of the big bucks bracket races are UNBELIEVABLE - if you know what I mean.

RF triggers which pickup the button impulses sent by the starters trigger are a fact. Why do you think you can get spark plug wire feedback which interferes with timing and the box itself?

Do you think there are just that many good drivers and combos?

It has been a computer video game for a while.

:-) peace

Oh oh! A black helicopter just landed on the grassy knoll!

Better call Jesse Ventura.

Here's another thing most don't know about the CJ's they have a wheel speed sensor that turns off the 2-step when there moving, can we say traction control? is this legal in stock or any other class. It looks like there are no rules for fomoco!!!!!!!!!!!!!!

Kinda like some stockers with Dedenbear timers controlling ignition timing.

Look-up tables are just that...program screens that allow you to change parameters and adjustments to your operation programs.....the programming codes are "beneath" this and ALWAYS have a "back door" to allow engineering the ability to alter any glitches or make necessary adjustments.....at the dealership level, techs do not have access to the back door and cannot alter this programming, they can only bring up the look up tables and alter the "enablers" .....

in the DBW system the throttle is opened by a simple servo motor through a gear drive....servos can be made to operate in "ms" millionths of a second (look at CNC equipment as an example)....to go from idle to full throttle you have to ramp up from the initial idle position to full speed then ramp down when you approach full throttle in order to not damage the system by slamming it open and closed.....for OEM they need to keep the ramping so the system will last a long time without failure....without long term durability, racing, the speed of the system can be altered to open as fast as you want......all you would need to do is alter the ramping as a percentage of full throttle (when the ramping would start) and the rate (how fast to go to full throttle) and you have throttle stop and traction control all in one unit.....this is programable to the point of being almost seamless to detection in operation....

and you can still let off the throttle at 1000' if you want to........
