Supported Crank Patterns
MAP_CRANK_MODE values:
 1 = 60-2 (58 teeth + 2 missing)
 2 = 36-1 (35 teeth + 1 gap)
 3 = 36-2-2 (30 teeth, cam sync required)
 4 = Custom (placeholder)
Cam Sync Handling
Cam sync logic is always active.
Monitors G40 at 0x286E. On rising edge, sets B_phase (0x2B02).
Previous value stored in RAM at 0x2B12.
Supports both 1-window (AEB/AGU) and 4-window cam sensors.
Usage Instructions
1. Flash the patched binary to your ECU.
2. Write a value (1-4) to RAM at 0x800A66 to select crank decoding mode.
3. Cam sync logic runs automatically to detect G40 edge and update phase.
4. Decoder logic sets B_syn and B_phase flags as expected.
