Signals decoded from both Megasquirt CAN output modes — Realtime Broadcast (generic MS3 frame set) and Dash Mode (compact dash-optimised frames). Both are decoded simultaneously; the gauge merges data from whichever frames arrive.
Enable CAN output in TunerStudio. The gauge decodes both Realtime Broadcast and Dash Mode frames simultaneously, so you can enable either or both in TunerStudio. Frame IDs in the Realtime set match the standard MS3 broadcast table (base ID 0x5F0 = frame 1520). CAN speed must be set to 500 kbit/s.
