Bosch was asked to develop the engine management system for the car. A relatively complicated and expensive component in general, Bosch imported the control unit, sensors and actuators for the car.
For the Nano, it created a blink mode that allows for the car's health to be detected even without a diagnostic tool. One can also know the fuel efficiency during the last five cycles. Despite trying to keep costs in check, Bosch also managed to have a limp-home mode in case some sensors on the EMS fail.
