Trackspeed Stage 2 VVT shortblock, EFR6758, E85, 452whp/427wtq@26psi. I'm scared.

It is my understanding that we are already halfway there...
We have Boost by TPS with closed loop boost. X axis is RPM, Y axis is Throttle position, Cel data is desired boost level.
Now, turn on booost blending. Create two separate targets. From there, go to "Table Choices"> Blend Curve (6) Boost1->2
Set X-axis parameter as Gear. (Not currently available.)
It sounds like something one quick firmware update away.
EDIT: ACTUALLY, gear is already supported.
What I would like to see is the ability to add ANOTHER Variable... Blend that table with another table... For example blend the boost blend table with another that adds a rotary switch.

We need a third 2D map for each boost control setting (1 and 2) which commands a percentage of the target based on gear. Gear on the X axis, Target% on the right.

...and that's where it comes to a screeching halt for me. Boost Target 1 is my pump gas DC% map, Boost Target 2 is my E85 DC% map. I already blend between them automatically based on ethanol content.

And this is where the non-open source nature of the megasquirt comes back to bite us. Adding a couple tables like that is an afternoon's hacking, but the license wouldn't let me give you a copy.
