MSII is pretty straight forward, the stock MPI injectors are high Z
so no problems there, the stock sensors need to have their values
mapped, and the file loaded to the MegaSquirt, easy as boiling water
check value, frozen to 0 check value, and use the easytherm program
to plot the waypoints in between, do this for IAT and CLT sensors
and you should be set. You will also need to connect the TDC sensor
for the MSII unless you don't plan on using the ignition table and keep
it firing with the stock system. I need the ignition retard when I hit 10
PSI of boost to keep the engine from pinging it's self to death
Good Luck
