None of the COPOs have Drive-By-Wire.

Hey ,thanks for that info.
So they leave off the Grid, or maybe feathering the gas pedal? ;-)

Its all Holley EFI, no grids are needed in a copo. This is an issue with NHRA and their HP factoring system. Guys at my shop constantly try to understand our rules and reasonings behind the HP factors of the combos out there, specifically the fuel injected cars. They are confused why the LSA's or the LS7's arent legal but a COPO is. These LS engines are mass produced in showroom vehicles that make 550-700 HP out of the box and we can't get them into the guide simply because they wouldn't fit a realistic class without being weighing a ton. Yet, a 632 COPO that makes close to 1,000, lets say even at 800, and is rated at 575? Thats laughable. If we want to entice more of a younger crowd, these COPO's arent the ticket. NHRA has to get the cars that are seen on the road, i.e CTSV's, supercharged corvettes, newer camaro's, and played with at all these performance shops, in the guide and let the new generation of racers get involved. Yes, the 632 COPO is awesome, I saw it at PRI. But the average guy walking around doesn't have 6 figures to drop on a racecar...atlease not all at once, lol.

All well and good but it looks like I'm not going to get the answer I'm looking for here.
I guess I better start a new thread. ;-)

My apologies Mark, what is the question you were hoping to get an answer to?

I'm guessing Mark is asking that the COPO could leave off of 20% throttle and then let the computer gradually open the throttle as it went down the track.

Yea thats not possible unless you have a drive by wire system. You can set up a signal or light on the dash to tell you when your throttle is at 20% and you can adjust timing according until you get to 100% open throttle. I dont know, the options are endless with the Holley stuff. Its beyond my full comprehesion
