I have an NX Boost Reference controller. Can use WOT or boost activation, along with RPM window and delay/ramp timing and percentage for two stages. Uses a simple NX program and uploads via USB from a laptop in about a second.
Just used it this past weekend, so it worked well but I'm buying a converter and switching back to a wot/window switch setup. Pm or text me at 940-64one-zero833 if you're interested
