as above, i'm an MS'er, i think it's a great thing, i've learnt so much about how an engine behaves with it.
what do you want to know, ms can fuel and spark properly, full wideband controlled adjustments if you want, so varying fuel would be no problem, launch control/anti-lag, boost control, nitrous control, shift lights, full stepper motor control if you wish.
i'm sure there is more, give me time to think
