How are you going to control the electric start and the eletric cool down procedure?
Havenâ€™t gotten that far yet. The first point of the project is a data terminal. Once that's working... I will work on the "Piggy back" electric start.
The ECU data is documented, so it won't be a problem. Once the data terminal sees a "Clear to start" from the ECU... it can ask if you want to start, then do so, using the engine speeds listed in the manual.
Assuming the terminal will be left in the model, it can go into a "Cool down" mode once it sees the engine RPM is VERY low, and the switch is in the Off position.
