The MAF is an estimated value of MAF, based on the CAN data for engine power and torque.

• Oil Temperature
• Fuel level

The following GPS data are streamed to HLT at 10Hz:

• GPS time
• GPS speed
• GPS lon
• GPS lat
• GPS hdop
• GPS alt
• GPS course

Please note that an external GPS unit is required, e.g. Adafruit Ultimate GPS Breakout - 66 channels w/10 Hz updates - Version 3.

The following measurements are optionally streamed to HLT over Bluetooth LE with 1Hz (additional D/KBUS2CAN module needed):

• Cat temperature
• Intake Air Temperature (IAT)
• Battery Voltage

If future versions of HLT enables support for other measurements (like oil pressure, brake pressure etc.), they will for sure be supported by airVent Display.
