MHD Flasher F-Series N55

N55 Monitor License

MHD Monitor License (unlocks the ability to data log and view up to 8 fully adjustable live gauges):

Monitor your engine behavior to make sure it is running perfectly using a configurable and very responsive gauge layout with up to 8 fully adjustable gauges. 50+ engine parameters are available at a glance and are logged in the background! Activate the logging mode to save the data to a standard CSV file for later analysis using the built in log viewer. Additionally, we will happily provide free logs analysis.

These are some of the available monitors: Boost, Boost Target, Lambda (AFR), Intake Air Temp (IAT), Ignition Timing per Cylinder, Coolant Temperature, Oil Temperature, Oil Pressure, Transmission Temperature, High Pressure Fuel Pump (HPFP), Throttle Position, Wastegate Duty-Cycle (WGDC), RPM, Speed, EGT etc.

    Advanced parameters that are not exposed by BMW are available for fine monitoring and tuning (depending on the DME software version if MHD is not flashed) like Timing Corrections per Cylinder, Boost setpoint, Active torque limiter etc.
