How to read a parameter card

Engine RPM MG4_RPMConfirmed

  • Request01 0C
  • Service 01PID 0C
  • Module7DF → 7ED
  • Every250 ms
  • Testing

Example reply from a 2024 MG MG4.

Bits 0 to 15 of the reply, 16 bits.

0xFFFF = 65535 → (65535 × 0.25) = 16,383.75 rpm

Formula
(val × 0.25)
Range
0 to 16383.75 rpm
Unit
rpm

Confirmed for 2022 to 2024. In testing for 2025 to 2026.

  1. The parameter's name and its ID in the OBDb. Confirmed shows when a response from a real car confirms the parameter.
  2. The clutch mark shows a Connectable, a parameter that Pelican surfaces in its interface.
  3. The service and PID/DID asked for, the control module it's sent to, and how often Pelican asks.
  4. The reply's bytes. The parameter's bytes are blue. Bytes for other parameters in the same reply are grayed out. Hover over a byte to see the parameter it represents.
  5. Where the parameter is in the response, and how Pelican converts the raw value into a value.
  6. A real reply, decoded. The raw value comes first, then the reading.
  7. Which model years have tested this parameter.

Commanded equivalence ratio EQ_RATSAE J1979Confirmed

Fuel systems that utilize conventional oxygen sensor display the inverse of the commanded open loop equivalence ratio (also known as lambda) while the fuel control system is in open loop. Will indicate 1.000 while in closed-loop fuel.

Pelican can show this parameter as the commanded lambda.
