Did the EGT show that as a dead cylinder?
It’s not like it’s EFI with an injector for each cylinder....... and one is on all the time.
The bsfc number is a reflection of the power being made and the fuel used to do it.
How is it that cylinder is getting a lions share of fuel, but the other cylinders aren’t being starved.
They’re all pulling from the same fuel source.
If it was really 10:1....... how much extra fuel would it take(lbs/hr) for that to happen on that one cylinder?
Is it enough to change the bsfc value by a full tenth(mid-5’s down to mid-4’s).
I know that had I seen those bsfc numbers, along with the overall richness of the fuel curve...... I’d have tried leaning it out to see how that might have affected the power/bsfc numbers.
Might have done something, might not have.
In order for the bsfc at peak hp to change from .534(from that screen shot) down to about .450, the fuel flow would have to drop by about 40lbs/hr(230’s down to 190’s).
