Few reasons I can't do that. First is that its buried in the engine , second i dont have an aux shaft on the motor and third if the signal drops below 250rpm the mil light illuminates. While that presents no practical problems driving the car it would result in a failure during the mandatory vehicle testing which I will have to do. So the arduino will produce a false 300rpm signal to the tach when the motor drops below 300rpm.
