MS0 and MS1 - both identical. Cut the b/w wire from pin 58 on the ecu and attach each loose end to the tabs on a simple on/off toggle switch.
The changes come when you change your ignition and fuel maps for either MS0 or MS1. Be brave! Play with MS1 and advance your ignition a few degrees at around 2000-6000 rpm and fatten the fuel curve in the same range. Flash to your ECU and take it for a ride. Switch the toggle over and feel the difference!
Certainly easier than changing out jets and mucking around with springs on a mechanical ignition advance.
