You might need to rearrange your rpm bins to give one lower than the idle speed. If that's 700 rpm, make one at 400 or so. And set is so the mixture with that is slightly richer than the normal idle. My car had a factory mod which used a solenoid air valve which opens when you select drive or reverse (controlled by the starter inhibit switch) to bring the idle up to the same as neutral. I kept that when I fitted the MS.
Similar idea as was used for aircon.
