Is the BMS-C a “learning” fuel injection unit?
• It is not “smart” in the traditional EFI way, but it does store certain values in its brain. The CPU on the BMS-C has a small area of “memory” which is used to store certain “values” (although we are not 100% sure what these values are). This area of memory is probably used to store the fault codes. The reason the BMS-C reset methods suggest 15mins for the power to be disconnected is it takes about 15mins before the values are lost from this small area of “memory” on the CPU.

For example, the computer knows that for a given RPM, throttle opening, and ambient air pressure that it should give X fuel, per the factory preset. It also knows via the O2 sensor if this is rich or lean. So it can apply a fudge factor for that combination to get the O2 reading that it wants and store it in the 2K of RAM. This is the learning part. With 2K it can’t g
