    I'm going to play devils out of here, but stop playing.

    Realistically, you don't know what the engine wants until it's actually running. I tune a lot of engines. I can build the same thing, 100 times, and every engine wants something different. Maybe splitting hairs, one two horsepower at the wheels, but ultimately most of these engines want the same thing as us....

    Just to drive down the road, and go hard.

      When the time comes, it will be started on bare bones tune (ICV off) and dialled in to idle smooth (warm engine) without the ICV. Once sorted, ICV will be introduced. All that "playing" is mostly for educational purposes.

        MS has 2 types of ICV arrangement: closed loop - ICV works to maintain chosen rpm (load changes, A/C etc) regardless of the engine temp. and it has an open loop mode (ICV is used during the warm up (cranking or idle).

        How is ICV configured in your ECU?
        Inbuilt MAP is used as baro only
        I use closed loop idle control with ICV works flawless with A/C

          are you still on Wolf or switched to something else? I was thinking to go with ECUnater per Rama's advice but my local runner stopped working with it last year.

            True. I got a stim a long time ago, and messed with it for about 15min, and it's been sitting in the drawer since haha.

              I think it's cool little kit (I bought DIY kit, I enjoy soldering :) ) and let's you check every tune setting on the bench. Really easy to adopt for any other ECU

                I’m still using the old Wolf. I will upgrade probably to Haltech as it’s the most common ecu that’s more than capable of my needs so finding someone is going to be easy
