Digital ECU Cheater I is a piggyback device equipped with an autonomous EFI fuel injection control mode. This makes the device suitable for, among other things:

- converting a flow meter to a pressure sensor (MAF->MAP)
- modification of analog signal 0-5V
- conversion of mechanical to electronic injection (among other things, this allows the use of LPG injection systems)
- control of the fuel system in the case of equipping a naturally aspirated engine with a compressor or turbocharger
- control of boost pressure (up to 3 bar overpressure)
In addition, the Digital ECU Cheater I is equipped with a communication port that allows the connection of the MultiDisplay multifunction display of engine operating parameters.

Configuration of the device is done via USB interface using the included PiggyProg software. The software allows you to edit maps (16x16 size), change configuration settings and log and view measurement parameters in real time.
