Parameters

The MG RX9 has 76 parameters.

● Confirmed◆ In testing○ Supported× Not supported

Battery

Control module voltage `VPWR`SAE J1979Confirmed

Power input to the OBD control module. VPWR is normally battery voltage, less any voltage drop in the circuit between the battery and the control module.

Pelican can show this parameter as the starter battery voltage.

Unit: V

0x00 = 0 → $\frac{0 \times 5}{255}$ = 0 V

Confirmed for 2025. In testing for 2023 to 2024, 2026.

Control

Absolute throttle position `TP`SAE J1979Confirmed

Throttle position at idle will usually be more than 0%, and throttle position at wide open throttle will usually be less than 100%.

Pelican can show this parameter as the throttle position.

Bits 0 to 7 of the reply, 8 bits.

Formula: $\frac{val \times 100}{255}$
Range: 0 to 100 %
Unit: %

Confirmed for 2025.

DTCs

Distance traveled since diagnostic trouble codes cleared `CLR_DIST`SAE J1979Confirmed

Distance accumulated since DTCs were cleared (via an external test equipment or possibly, a battery disconnect). This parameter is not associated with any particular DTC. It is simply an indication for inspection/maintenance, of the last time an external test equipment was used to clear DTCs. If greater than 65,535 km have occurred, will remain at 65,535 km and not wrap to zero.

Pelican can show this parameter as the distance since trouble codes were cleared.

Calculated engine load `LOAD_PCT`SAE J1979Confirmed

Represents the amount of work the engine is doing. Expected to reach 100% at wide open throttle/wide open pedal at any altitude, temperature or rpm for both naturally aspirated and boosted engines. If engine load is limited for powertrain protection e.g. engine/turbocharger protection, this value may not reach 100%. For hybrid vehicles, indicates the torque produced only by the internal combustion engine, not the torque being delivered by the entire powertrain. For electric vehicles, the meaning of this parameter is undefined.

Pelican can show this parameter as the engine load.

Commanded equivalence ratio `EQ_RAT`SAE J1979Confirmed

Commanded fuel/air equivalence ratio (lambda): actual A/F ratio over stoichiometric A/F ratio, so above 1 is lean and below 1 is rich. Multiply by the fuel's stoichiometric A/F ratio for the commanded A/F ratio (gasoline: 14.64 x 0.95 = 13.9). Systems with conventional oxygen sensors show the commanded value in open loop and 1.000 in closed loop; systems with wide-range (linear) sensors show it in both. On engines whose banks are controlled independently, this is bank 1.

Pelican can show this parameter as the commanded lambda.
