What does load mean on obd2 Scanner?
A search on google found this: Calculated Load Value — Indicates a percentage of peak available torque. Reaches 100% at wide open throttle at any altitude or RPM for both naturally aspirated and boosted engines.
What should your calculated load be at idle?
So, the baseline of our formula for calculated load at idle is 3.4 grams per second (current airflow) divided by 10.35 grams per second (max airflow) equals 33%. In the last column we saw that normal CL readings at idle could be between 30% and 50%.
What is high engine load?
The engine load basically determines the capacity of the engine to produce power. Whenever the load on engine increases, the engine speed decreases. To compensate this loss in engine speed, more fuel is supplied to the engine. When the load is greater than rated load, we say that engine is overloaded.
How is the load value calculated in OBD?
Calculated LOAD Value (PID 04) The OBD regulations previously defined CLV as: (current airflow / peak airflow @sea level) * (BARO @ sea level / BARO) * 100% Various manufacturers have implemented this calculation in a variety of ways.
How is OBD calculated with no airflow sensor?
The graph shows good accordance between OBD collected data and OBS measured for all the ranges. If the airflow sensor is not installed onboard, it can be calculated creating a 3D map with input data rpm and engine load. This map need to test the engine in all the ranges of use: for all the rpm and all the loads.
What does OBD stand for in a car?
That’s where OBD comes in. What is OBD? On-Board Diagnostics (OBD) is a system that monitors a car’s computer system and reports diagnostic trouble codes. Devices like an OBD-II code reader can read diagnostic trouble codes (DTC) that the system stores when something goes wrong.
How is CLV calculated in the OBD regulations?
The OBD regulations previously defined CLV as: (current airflow / peak airflow @sea level) * (BARO @ sea level / BARO) * 100% Various manufacturers have implemented this calculation in a variety of ways. The following definition, although a little more restrictive, will standardise and improve the accuracy the calculation
