awesome did you log knock counts??
If so where did you end up for timing @11.5 AFR at high boost for that turbo??
I always like to know the end result of each setup........nosey

I did not get "that" aggressive with timing and there was no Knock detected. I think there is still timing to be added, especially after the turbo begins to drop off. I'll look at my datalog and see what it looks like, I know it pulled like crazy and I have never felt the k26/6 pull like that. Will post more later.

that looks pretty good
you may try to add a little fuel up top looks like it may be close to 12:1
actually you could add a little from boost onset and add some timing there too.
just pay attention to knock counts.
You will certainly need to retune with the other turbo for sure as it is dropping off and it looks slightly lean now in the upper rpms it will be much worse with the added cooler air.
What is your rev limiter set at.

Simple steps to prepare for E-85.
replace any old fuel lines to new stock. Don't worry about them for another 5 years.
upgrade injectors and fuel pump to around 40% (safely) More capacity than would be needed for gasoline.
Tune ignition timing like it was on race fuel.
Re-tune AFR's to .8 lambda.
Spend lots of time on the cold start up map..
you're done. .... seriously.

Here is a Megasquirt website about the flex fuel sensor found on GM vehicles that allow for automatic compensation to whatever blend of regular pump gas and E85 you may have in the tank...

The flexifuel sensor looks just like a lambda sensor. But you need an EMS that can run it.
DTA has inbuilt functionality to run a flexifuel sensor. Should be able to do something similar with the Link G4 storm if you're creative.

Something strange like 8.5/9ish a/f.
11.5 is the same a/f im shooting for, for pump fuel. So what you're saying is the values on my readout are going to remain the same between pump fuel and E-85? I never would have thought that.
