dimatennis84@mail.ru, Топливная коррекция на больших скоростях тоже ноль, нормально это ИМХО.
Про нагрузку двигателя не знаю, норма ли это...

Absolute Load Value (PID 43)
The absolute load value has some different characteristics than the LOAD_PCT defined in PID 04 This definition, although restrictive, will standardise the calculation. LOAD_ABS is the normalised value of air mass per intake stroke displayed as a percent.
LOAD_ABS = [air mass (g / intake stroke)] / [1.184 (g / intake stroke) * cylinder displacement in litres]
Derivation:
air mass (g / intake stroke) = [total engine air mass (g/sec)] / [rpm (revs/min)* (1 min / 60 sec) * (1/2 # of cylinders (strokes / rev)],
LOAD_ABS = [air mass (g)/intake stroke] / [maximum air mass (g)/intake stroke at WOT@STP at 100% volumetric efficiency]
* 100%. Where:
— STP = Standard Temperature and Pressure = 25 °C, 29.92 in Hg (101.3 kPa) BARO, WOT = wide open throttle.
The quantity (maximum air mass (g)/intake stroke at WOT@STP at 100% volumetric efficiency) is a constant for a given cylinder swept volume. The constant is 1.184 (g/litre 3) * cylinder displacement (litre 3/intake stroke) based on air density at STP.
Characteristics of LOAD_ABS are:
Ranges from 0 to approximately 0.95 for naturally aspirated engines, 0 – 4 for boosted engines,
Linearly correlated with engine indicated and brake torque,
Often used to schedule spark and EGR rates,
Peak value of LOAD_ABS correlates with volumetric efficiency at WOT.,
Indicates the pumping efficiency of the engine for diagnostic purposes.
Spark ignition engine are required to support PID $43. Compression ignition (diesel) engines are not required to support this PID.
