Here is some great reading on the Megasquirt family of control units.....there are lots of options to choose from and really need to read and understand what you need to decide on the appropriate unit....I chose the MS2 which has the ability to fire 8 low impedence injectors in batch fire and full timing contol via map/RPM inputs....also yes the MS2 has e-85 sensor ability and control.....quite a few other controls available with the MS2 they just need to be wired up.
