Remeber to warm it up on the stock ECM before trying MS and leave the set timing connector disconnected initially. Then all that is left is fuel to set up. If it will not idle on the stock ECM with the set timing connector unpluged - give the dist. a twist so you have say 10-15* timing BTDC initial. You can set it back later.
Make sure you get RPM showing on the tuning screen.
