Caveat: I believe this is a problem with my car and nothing to do with boostbutton or the cals/computer.
Seems I've always had issues with computer controlled boost so computer controlled boost is my life mission at this point.
This is a stock turbo II 1988 Lancer with a 2.5" exhaust, boost button flashable smec, all new vacuum lines. Boost is completely controllable with a grainger when installed.
Ever since I've had this car it has had no computer controlled boost. Using MPScan you can turn the diagnostics on and cycle the boost control solenoid. I figured it was a solenoid issue even though it will work fine. I installed a GM boost control solenoid using the same wiring and cycled in through mpscan and it cycles fine with what seems like click click pause click.
Set it up T1 style and T2 style and still no boost control.
The way I figure at this point I need to start playing with MPTune to get the duty cycle to try control the boost.
I do see in the below link one pin for the wastegate solenoid.

So now a list of questions:
Is the solenoid ground wired to specific pins in the smec?
Could I test the wires to the smec connector for resistance?
Is one of the solenoid wires grounded?
What can I change in the Calibration to change the way the computer actuates the boost solenoid?
