This electronic system is fitted to vehicles equipped with a radial piston distributor injection pump of Bosch VP44 and VP30 type. In this family of tuning boxes, the correction of data is based on information coming in real time from the CAN-bus network (digital data bus). It is therefore direct priming of the pump which generates the increase in power.
