I would say the biggest variable is the nut installing the belt.And more, that I can't think of, right now.

There's no nuts in the belt?I would say the biggest variable is the nut installing the belt.
Yes BHWtruman, your engine code is BHW, right?
Also, did you look at momentary fuel consumption in Block 015? What does that say?
First change, which is obvious and you can notice it even without any tools, is the engine sound. So to change that sound at idle so much, it must consume more fuel, for sure.Well, if your EGR operates like ours do, simply watch the fuel useage on the scan tool and wait a couple minutes for the EGR to fully close. Note any changes.
Not supposed to be. He is talking about this thread.There is no link in your post!
I agree with the effect on injection pressure that Mako describes below. I also think this would have an effect on dynamic compression ratio but I'm not that well versed in the theory to debate the point.Well, sad news: I was thinking about this lately.
What I have been thinking -and maybe this was mentioned already - is that setting this "torsion", is just tricking the computer into thinking the timing is someplace other than where it really is. Maybe by adjusting this torsion, the computer thinks the timing is different and adjusts for it, giving advanced or retarded injection timing, depending on the torsion setting.
I just can't see that hair of movement make any difference in airflow or anything at all in the injector stroke.
Yes, but the fuel is potentially injected later in the cycle due to the extra duration.Shooting from the lip.......the cam timing decides the profile of the injection stroke in relation to the piston. The pressure builds up from zero (well there is residual) peaks and is maintained for a limited period before falling off. The start of injection point controlled by the ECU may be as late as TDC while idling to 35-40 degrees BTDC at speed and light load. Set the torsion outside of the factory range and the SOI will stay where it is supposed to be but the actual pressure and or available fuel will not meet the calculated value. The ECU may detect that the motor needs more fuel to maintain a given load/speed and injects for a longer duration to deliver the required fuel. The MFD shows this as increased fuel consumption when what is really happening is that the fuel pressure available was lower requiring more duration to inject the same amount of fuel.
