I have an aftermarket electronic boost control solenoid running in 3-port interrupt mode. It plugs into the stock harness, just like the stock solenoid. The same principles apply when tuning for it, but it requires much less wastegate duty cycle (at least 25% less) than the stock solenoid.
Can I still follow the wiring diagram above? Or does it need to be wired differently? Here is a link to the product and manual:
