Before we dissect the specific v2.06 update, it is crucial to understand the hardware. Infinitybox utilizes a master/slave architecture:
The firmware file infinitybox-install-cm2mt2-v2.06 is specifically designed to update the operating system of the CM2 and MT2 devices simultaneously.
After both units are updated:
V2.06 introduces a new dual-channel verification system. After installation, connect your Master Cell.
Even seasoned builders hit snags. Here is a field guide.
Before you download, ensure your hardware is compatible. This firmware is not backward compatible with the original CELL-MASTER (v1) units. You must have:
Cause: v2.06 increases bus speed to 500 kbps. Older POWERCELLs (pre-2021) cannot sync.
Solution: Update all POWERCELLs to firmware v4.1.1 using the same USB-CAN tool. This is not optional.
The "MT2" profile typically maps to 16 high-current outputs (fused at 25A each).
| Switch (MASTERCELL Port) | Output (POWERCELL Channel) | Logic in v2.06 | | :--- | :--- | :--- | | Ignition (Toggle, Port A1) | PCM Ignition Relay (PC1 Out 1) | Latched, 2-second crank delay | | Headlights (Momentary, Port B3) | Low Beams (PC2 Out 4) | Toggle on/off with status LED | | Fan Override (Port C2) | Radiator Fan (PC3 Out 2) | Override with hysteresis (205°F on, 195°F off) |
