Fuel Equation

Recommended Posts

Hello guys,

i would like to understand the calculation of the injection time.. In my opinion, it should be relatively simple to understand.

If i have a warm engine (no cold start enrichment etc), and constant difference between fuel pressure and intake manifold pressure, the Injection_Effectiv_PW should be calculate so:

Injection_Effectiv_PW_calc=constant_conversion_factor x Master_Fuel x Fuel_Table1 x (1+Lambda__Fuel__Corr/100) x (1+Accel_Fuel/100) x (14.7/AFR_Target) x (1+IAT_Fuel_Corr/100) 

If i plot Injection_Effectiv_PW (measure)  over Injection_Effectiv_PW_calc, i haven't a straight line. I don't understand, what i do wrong? Is there another corrections for the injectors?


Thanks for help.


Best regards

If the fuel equation is set to "Load=MAP", then MAP is a multiplier for PW also. 

i.e at MAP = zero, PW = 0.  At MAP = 200KPa, PW = 2x calculated.
