What to monitor on this engine

Coolant temperature and RPM are practical first readings for this engine. Add intake-air temperature for a view of intake heat under repeated load. If you display pressure, keep absolute manifold pressure distinct from boost relative to atmosphere. Engine RPM and coolant readings describe the combustion engine; they are separate from traction-battery measurements. An automatic-transmission temperature reading belongs to the automatic gearbox; it should not be labeled as a manual-gearbox reading.

Installation approach

Position the gauge close to the factory instruments while keeping the driver’s normal control reach unobstructed. Fit the mount from your normal seating position before fixing it in place.

Connect the OBD-II adapter at the vehicle diagnostic connector and secure its cable along fixed trim. Leave the connector accessible for servicing. Follow the Flock user manual for gauge power, adapter setup and wired-sensor connections.

OBD-II and wired readings

Choose standard OBD-II readings such as coolant temperature, RPM, intake-air temperature and vehicle speed in the gauge menu. Use wired sensors when you want an independent oil-temperature, oil-pressure or boost measurement.

Configure your gauge

The gauge displays whole-number OBD readings. For temperature definitions labeled C, use the gauge’s temperature preference to choose Celsius or Fahrenheit.
