I'm trying to help a friend to get his tune right.
2012 CVO 110 RG
PV TT, Kury PowerCell with FullSac 2.0 cores, stock 255 cam.
Bike runs fine and the AT seems to work ok.
He checked for exhaust and intake leaks and found none.
How ever the rear VE's are high, hitting the max 127.5 limit. We've been sticking to capping the values to limit ridiculously high engine ci.
I was going to try to use the CDE tables to lower the VE's before increasing the ci.
There were a couple of contradicting posts, as to which way to adjust the CDE values in order to lower the VE's.
Lower the CDE to get a lower VE ?
MLV plots seem ok to me and the injectors have about the same running times.
Any other ideas for the next step ?

This is Joe's post how to do it, an other post had it the opposite way.

"When adjusting the EGR table/s it will vary from bike to bike, build to build. As a general rule of thumb if you want to reduce the VE values in the lower RPM range (~0 - 2000) you would double the amount you want to drop in the EGR table. So if you wanted to drop the VE by 10% you would drop the EGR table 20%. In the mid RPM range (~2000 - 4000) it changes to triple, 10% VE needs 30% EGR change. In higher RPM areas it takes even more, 10% VE needs 40% EGR change."
I use this now and it works ok.
You should choose scale and see which engine displacement value the motor need.
