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.

Yeah you can do blending by gear. You just need 2 well setup tables. I blend with a rotary switch instead of by gear because thats what works best for me.
Though, to be honest even wastegate will be more power than i'd hand an inexperienced driver.

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.

And to make it worse the latest firmware source isnt even released yet so you cant even get far enough to break the TOS.
