That's worked!!!
Using sub-injectors channels A and B (have to wire them both to a single ground/control wire on stock boost solenoid, cutting original one off) on Blue e-manage and just re-routing the hoses on stock Boost Control Solenoid Valve - we have created a working EBC which can be controlled by sub injector tables!!!
You just have to put a T piece (with a small opening to atmosphere) to vent pressure off when solenoid is closed. That one goes after solenoid, but before actuators.
Didn't fine tune it yet... but at first glance = 100% across table gives us stock Boost levels, 0% across table = unlimited boost!!! Did put in some other values (we held 0,9, but had it spiking... so have to work those things out), but our notebooks battery had died... so will continue later (prob tomorrow).
You can actually save as many tables as you would like... Stock boost (along with timing, airflow, injectors maps), small power up, race settings...
