Confirmed for 2010, 2022. Supported for 2007.
Calculated engine load LOAD_PCTSAE 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_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.
