Smart injection has 5 ground activation outputs as well as a programmable 0-5V and of course 7 inputs.
You have many, many ways to do what you are seeking. For example, our smart injection failsafe has an optional status monitor that can detect a problem in the line. If it detects a fault, one of the outputs can activate a wastegate solenoid. Thats option #1. Option #2 which may work for some of you...If you have an aftermarket electronic boost controller..use one of the smart injection outputs as the ground to your electronic boost controller. Any problems in the line, hardware, out of water, de-activate the ground. This SHOULD disable the boost controller and bring you back to wastegate pressure. Again, you will need to make sure your boost controller works in that fashion, if not you can do option #1.
