DescriptionDefi-Link Meter ADVANCE BF is a link meter that is used by connecting it to the Defi-Link Advance Control Unit SE or Advance Control Unit.“BF” stands for “black face,” and is the name given to meters that are completely dark and the dials cannot be seen when the ignition is off. BF type meters are illuminated as soon as the ignition is turned on, so that the letters and scales can be seen even in the daytime.This meter measures the engine revolutions per minute and plays an important role in maximizing engine performance. When driving on the highway or at full throttle, it is important not only for general driving and economical driving, but also for tuning the engine, such as detecting the timing of gear changes and preventing over-revving.
