v0.1.0 - Honda OBD1 ECU (OKI MSM66207) Emulator & Testing CLI

v0.1.0 - Honda OBD1 ECU (OKI MSM66207) Emulator & Testing CLI

First official release of hondaecu-cli, a high-performance command-line emulator and ROM testing suite in Rust for Honda OBD1 ECUs (P28, P30, P72, PR4).

🚀 Features & Capabilities

• Byte-Precise OKI MSM66207 Virtual CPU Core: Interprets raw machine code opcode bytes line-by-line using a virtual register file (A, DP, X1, X2, USP, SSP, LRB, er0–er3, r0–r7) with word/byte accumulator mode switching (DD flag) and borrow-correct carry flags (CF).
• Full 2,623-Opcode Table Specification: Complete instruction specification decoder generated directly from 66207.op.
• Microsecond-Accurate ISR Timing: Simulates hardware timers (TM0–TM3, TMR0–TMR3) and distributor position pulse interrupts (INT0 CKP crankshaft pulse and INT1 TDC/CYP cylinder position pulse).
• 10-bit ADC Hardware Conversion: Simulates MAP, TPS, ECT, IAT, O2, Battery Voltage, and VSS.
• VTEC Spool Valve & Pressure Switch: Models VTEC spool valve solenoid engagement outputs and oil pressure switch feedback hysteresis logic.
• UART Serial Datalogging Protocol: Implements serial RX/TX protocol handler (vector 0x01FD, Baud rate 38400, command frames like 0x20 sensor payload data).
• 85-Test Exhaustive ROM Matrix Suite: Sweeps 400 fuel map grid cells, 400 ignition map timing cells, environmental trims (cold start, battery dead-time, overheat retard), and rev limiters.
• Complete 30-DTC OBD1 Honda Fault Code Support: Covers all official Honda OBD1 fault codes (DTC 0 through DTC 92).
• Interactive REPL Console: Live interactive shell to step instructions, set RPM/MAP/TPS parameters, dump memory, and monitor calculated fuel injection pulse width and IACV duty cycles.
• Blazing Performance: Executes 9.01+ Million Instructions per second (~9.01 MHz virtual CPU speed) in Rust.
