The last RPM block in the pull was 7165 pretty much just like the plot reads...

 

With VDR, you have to trim the max RPM down until the curve averages correctly. You have to remember that VDR is using mathematical averaging over a number of cells, depending on the smoothing. So, you can't go right to the edge of your RPM from your log, or the averaging gets screwy at that point. Usually 100-300 RPM before the end of your pull works out well.

 

It doesnt matter. Read this..

 

Updated with boost plots

 

Why didnt you fix the VDR chart?

 

I am gonna go do another rip tonight up to 7800 then post that up... with new boost plots too...

 

But you can just take the plot you already have and just use the "max RPM trim" to fix it and then it will be fine. No need to make another run.

 

Okay everything updated

 

Nice.

Your using the profec spec II for boost control right?

 

^ Fred was just running 18psi wastegate pressure. Not sure if he has the profec on.

 

?? Logs say he was boosting 26 tapering to 23/24??

 

Yes profec b spec II... When we were ironing out the tune we were running wastegate pressure and I was creeping to 27... but it helped us hold load a bit to tune midrange better. Then Sunday I turned on the boost controller, and we finished the tune ...
