The real beauty of the Megasquirt is that it is a complete ECU. It can be programmed for TBI or multi-port injection. You can pull the ECU off a 4 cylinder TBI set-up and drop it onto a monstrous V-8 application and simply re-program it.

Firing order makes no difference to it. It is not application specific. It works either on MAP or MAF. (manifold air pressure or mass air flow).
