How come that PD engines typically show a larger spread between injectors than non-PD ones? For example, the ALH we have is at around +/- 0.05mg/Stroke while the BXE (PD) is +/- 0.7 to 0.9 mg/Stroke. would it be Injector Opening Time, % Duty Cycle or similar? If so, 023 relates to 013 - as flow should be proportional to opening time.Ĥ. What about group 023? This appears as undocumented, but it seems to be closely related to 013. I believe that usually - when there is no actual injector issue - all values add up to approximately 0.
What are the 'acceptable' ranges for values in Group 013?Ģ. This is showing how the ECM is balancing the power for each cylinder at idle to account for variations in component tolerances, jet sizes, compressions, etc.).ġ.
This group shows the smooth running control injected quantity cylinder 1 - 4, left to right.
First of all - I'll say it just as others said it before: You guys are great! I really, really mean it!
