5 Extensibility

Bosch Motorsport developed a lot of extras for the ECUs. That is e.g.:

– Displays

– Data loggers

– Telemetry units

Find more information on: www.bosch-motorsport.com

Moreover, you can expand some additional functions of your ECU by sending us the serial

number. Than we will send you the licence for:

– E-Gas

– Knock control

– Traction control

– Variable valve Timing

– Near Bank/Far Bank
