Drive By Wire
 

Drive by wire is a safety issue, remember Toyota, and it is way to easy to cheat. Run tracing is easy. Traction controle you bet. Foot against the floor and only 60% throttle for first 1.296 seconds. Almost forgot where do I hook up the return spring, so I dont go flying of the end of the track at wide open throttle.

NHRA change the rule : No Drive By Wire.

I'm glad that you brought this up! Didn't the Rule Book address this issue at one point in time? Something along the line of there having to be a positive conection between the gas pedal and the throttle body or carb? I seem to remember it back when throttlestops were first turning up because of some real hokey stuff being tried.

Gotta love the NHRA! Larry, 2009 Rule Book page 253, 1:12 Throttle. Would YOU please read it and tell me what you think? I'm reading that the CJs ain't legal!

neither is a C5 or C6 vette, or a new caddy. NHRA would have to approve alternate throttle bodies, as to the best of my knowledge no one makes a kit to retrofit a fly by wire tb to a cable operated

Didn't Matusek have an issue with their Mustang when they WANTED to & DID convert their setup to a throttle cable instead of a wire and tech bounced them because it wasn't a factory set up? They did it for the safety of the setup if I remember correctly.

UMM leaving off the top.. Can when say timers???

Re: Drive By Wire
 

you know Keith, I hadn't thought of that. If you had a device that would send a default signal ( like a two step) while you ahd a particular button depressed it could easly be wired to a timer to interrupt/delay the throttle signal. Nothing would appear weird from the outside of the car

Holy crap another can of worms, how will they sweep that under the carpet?? Rule Change to follow I bet !

Drive by wire is covered in the 2011 NHRA rulebook. It can be found in the STOCK Section 10A, page 4 under FUEL INJECTION. The 2nd sentence reads as follows;

"If OEM throttle body (s) was equipped with electronic throttle control (i.e., drive by wire), the throttle body (s) may be adapted to mechanical throttle linkage if an aftermarket OEM-type electronic-fuel-injection system is used."

Anyone wanting to download the 2011 NHRA rulebook can do so by going to NHRA.com and click on the archive section. When the archive page comes up, scroll down to 11/17/10 for the rulebook. BTW the rulebook download is free to members only.

The throttle position has the least effect on the new cars. That from someone who knows.
