    You need to update your ECU firmware.

    Thank you. The car is cursed. Starter seems to want to stick now, never ending issues.
    When adjusting idle on the ECU (setting desired idle), I've read the suggested RPM, etc., for certain setups. My initial was 1050 RPM (forced induction). I was curious if there's a suggested way to find desirable idle besides just adjusting the ECU settings? I think I can go lower.

    You'll just have to try it and see if the idle quality suffers.
