Anyone know Holley Commander 950's? programming?

In many application I use a Neon IAC. It is a solenoid valve that provides throttle bypass air, and is driven by PWM (pulse width modulation) with just one low side mosfet. It opens in a linear fashion based on duty cycle. I used it with some modifications, to replace the idle control motor on the Turbo 2.2L TB. I also use it in a universal way on VWs with hose connection on a simple manifold. With a MAP system, fuel is automatically added to match the air. The idle speed control was very stable. I have a bunch of them, and will send one if you think you can use it. It will be a way to make your 4B-TB work with an improved ECU that has MAP. I will post a picture in a day or two.
