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........
