I didn't know this. Adam at Stillen was one of my sources of information and he never revealed this. He is the one who told me aobut this 4 second thing. The way he explained it, the computer allows the 4 seconds for "diagnostic" type work. He said that the factory was woried that over four seconds and you would grenade the engine. He also indicated that it didn't matter where the signal was interrupted, the ECU would react the same way.

From what I undertand, your only options are to buy an ECU or run really short courses.

I would guess that if you were able to block every other pulse from the vehicle speed sensor, you would theoretically double the speed before the limiter kicked. I discussed this option with both Sven and Aaron back before the modified ECU's were legal. I was told that their interpretation of the rules would make modifying this signal illegal.


..Also, the ECU does know fourth and fifth gear. There are sensors on the transmission indicating each of those gears.
