k fuku Posted September 21, 2023 Report Share Posted September 21, 2023 Engine Load What is the value this item is calculated based on? When I check the logs, I always see a number that is very close to the MAP. I don't really understand what I should be using this item for, so I would like your advice.

Adamw Posted September 21, 2023 Report Share Posted September 21, 2023 Absolute load is a standard SAE J1979 diagnostic variable. Roughly speaking it is the engine air mass flow relative to the max possible mass flow based on swept volume at standard atmospheric conditions. So an NA engine with a VE of 100% would have an absolute load of 100% at WOT. The same engine at 1bar boost and 100% VE would have an absolute load of 200%. Absolute load is directly proportional to the maximum flywheel torque available. By default in the Link ECU the absolute load runtime is only used for the torque estimation calculation. You can however use it for the load axis of your ignition table or some other function that is influenced by torque such as power management or diff control etc if you wish. k fuku 1 Quote Link to comment Share on other sites More sharing options...
