This is our CMGS Autolearn kit for BMW N54 and N55. For the N54 you use the boost input, for the N55 you use the MAF input. This system has an autolearn failsafe that will tell you if you have any issues with the system such as failed pump, solenoid, kink in the line, hose problems, etc. The 0-5 output will send a signal to your JB4 or compatable tune to allow auto map switching. Included in the price is a complete kit with tank, fittings, CM10 super atomizing injector and so forth.
