I used an MT8 file to tune my 2010.5 CUSE.  I followed all instructions and asked many questions along the way specifically around EGR adjustment.  Now that my tune is complete, I would like to compare my EGR values to other CVO TTS users who did the same.

The bike is a 2010.5 CVO ultra and I started with tuning file ETA009-03.  The bike has a ventilator AC and Rinehart TDs.

First here are the before and after EGR settings.  The original's are labeled with an Ocal.


Here is the front VE table


And the rear VE table


Originally, the EGR settings between front and rear were pretty close to each other.  By driving the 50 and 60 VE together, I made the front and rear EGR settings separate.  I have not seen anyone plot the final EGRs they used so I'm wondering if these look OK to you guys?

from what ive read about EGR  tuning , results will be varied a lot, depending on how far you are willing to go  doing it.  I do know a few tuners stated they wont do the EGR part of the tuning because of the extended time needed to do it.

Thanks Tim, it was a lot of work for sure.  For those who have also performed all the EGR runs, I was curious as to what their curves looked like.

over in harley tech talk there is a lot of discussion and a few  egr data shown that has been done by menbers on there. and yes ive heard it is a lot on tuning to get it correct as ppssible
