Using a wheel speed sensor and a pot input to determine vehicle speed and current gear selected, PCM will control the activation of the ignition interrupt and pneumatic solenoids based off the programming. I’m doing it so I can’t bang down through the gears too fast and overrev the engine. The PCM will not activate the solenoids if it’s going to over rev the motor, it will wait until rpms drop past a safe point then shift to the next gear. Lol that’s super badass. --- _[View the full topic](https://forums.speedlife.net/t/my-cahr-killah-dsr-class-racer/238150)._
