How to read automobile log data

It should be noted here that the log data comes from my own car, and the ECU is specially adjusted by myself. The recording software mes simplifies some irrelevant items for the convenience of reading, such as the EC V2 intake kit, the GFB DV+ intake and pressure relief valve, the project α 200 molybdenum large flow head section, the middle and tail section of the original factory, and the ambient temperature 15 degrees.

Log related sensor? item description

Why don't you analyze it here first? Log's project? The surface is a mixture of pictures and texts, so the life of ECU users is so boring: vehicle speed and engine speed = through these two items, the current gear can be analyzed and the load can be deduced at the same time. The higher the gear, the greater the load.

Ignition advance angle = does early ignition mean that the piston reaches compression? Before the dead center, the spark plug ignites and ignites the combustible mixture in the combustion chamber. The angle of crankshaft rotation from ignition time to piston reaching compression stop point is called ignition advance angle. The ignition advance angle when the engine can obtain the best power and economy is called the optimal ignition advance angle.

Intake pressure = absolute value of intake pressure after throttle, also? The measured value of the sensor that calculates the empty flow.

Intake air temperature = temperature after intermediate cooling and cooling control.

Air flow = air mass actually participating in combustion calculated by air flow sensor according to pressure and temperature, which is used to correctly calculate fuel injection quantity.

The formula is as follows: Wa=HP×A/F×BSFC÷60.

Horsepower = watt× 60 \ a/f \ bsfc

BSFC=Wa×60÷HP÷A/F
