John,,,it will activate ,,you just dont hear it,,,car will eventually slow to the 3500 stutter,,,,,only bad thing about doing that?? if the chip is on for any length of time,,,it will load the cyliders/headers/mufflers and could cause serious engine damage,,,,,,back in the thottle stop days,,,I blew the mufflers in half on a racecar doing the same thing


stockers (with any brains) arent doing this,,,if anything,,,they are hitting the high side....possibly with a switch to deactivate it if needed,,,,,here is the theory,,,,(1/8 mile racing tested),,,,,the ET of a car is directly related to the RPM...meaning that, if a car is running quicker,,it will make more rpm and exactly the opposite,,,the less ET,,,the less rpm,,,,,SO,,if your car is turning 5500 at 630ft,,,,and the next time is turning 5550 at 630ft,,your car is running quicker,,,,,,,,,Im using a 5500 chip as an example,,,,,,,if a car hits a 5500 chip at 630ft and the next run hits it at 625ft,,,,the cars is on a quicker pass BUT hits the chip to slow it down and put if back on pace,,,,,the same works for it being slow,,,,if it hits the 5500 at 640ft,,,it was on a slow pace BUT the car has run wide open longer to again put if back on track for the desired ET,,,,,,,,,,,,now letting a car hit a chip this close is undetectable to officials and if the driver didnt know it,,,he wouldnt even notice it,, with the exception of it would seem to just quit pulling,,,,,,contrary to belief,,,it wouldnt run up and just stutter like mad,,,,it just slighly bouces against the llimiter,,,,now if you held it on down for another 2 or 300ft,,,it would stutter like mad,,,,,,,,,,

IF THIS IS GOING ON,, this is how its done,,,,a switch connected to the high side 2 step to turn it on after the shifts,,,or car is being short shifted and run thru on the chip

the same issue could be used with timing retards,,,its just not as effective as using a 2 step

AGAIN,,,, ,I WANT TO STRESS,,,""IF"" THIS IS GOING ON,,,,,if I were an official,,,I would be looking for RPM chips that wasnt accurate (reasonable),,,,3 steps,,, or wiring to the 2/3 steps where they connect to the MSD,,, I would be looking into the programs of EFI cars to examine what type of timing they are using on top end,,,,and also looking for timing retards in carb cars

the problem,,if one wants to cheat,,,,officials just cant stop it,,,,,an LED tach can be used to same way WITHOUT any of the above mentioned items and it will work,,,,

if alot of you racers will examine runs,,,you will see that alot of the runs dont add up,,,,alot of racers are getting info inside the car to make calls on the track,,,,whether this is legal??? dont know,,,,,,,,Is it illegal for me to watch my LED tach till it rolls up to 6100 and let off???,,,the big analog tach arent very reliable,,,but the new LED readout tachs are,,,,,,,,is that illegal???? should it be??? Just like stated above about hitting chips,,,,should that be legal???? what if you didnt want to blow motor and it hit a 6400 chip every pass???
