You need the Motec ignition expander to run 8 coils, the M800 only has 6 ignition outputs as standard. If you use the expander then you can drive the 8 coils of one output. You shouldnt need a booster because the coils will have sufficient output, just need to make sure you get your axis tables correct so you get your dwell times right so you dont burn the tips off your plugs.
