Hi All, I am into minis, something a lot of americans probably won't have even heard of never mind seen! Up until recently minis had single point throttle body injection. You can pick up the inlet manifold, throttle body with the following sensors, The system is a MAP system. I was just wondering how few sensors I need to make it work. Make my own ECU and keep it simple. Calibration would be done on a dyno using a lap top. No need for a Heated o2 sensor, don't need it to learn really. I can pick up these units for about 50ukp!!
