The trend has been to change the fuel injector flow rate, flow per single pulse and base constant at desired EGR.
If both flow rate settings work properly, there should be little to no change of the base constant required because you've effectively accounted for the injector size increase with the two prior settings, lowering the base constant afterward should effectively lean out the mixture.
So except for a small change of the base constant, it should remain pretty much the same plus or minus a little fine tunning, in other words ther is no reason my base constant should be as low as I have it set; 40 which I arrived at by listening to idle however during a test drive it appeared to be very lean and now with WBO2 monitoring at part throttle in neutral it is going as high as 19:1 so the base constant is definately going back up to normal.
That explains the hunting during idle.
Am I reasoning correctly?
I also accidently made a single inject calculation based on the difference in engine size instead of the difference in injector flow rates.
