MSX Expansion Board & SSR

Just an update:

  • A while ago I ordered an MSX Expansion Board for the MegaSquirt III. This allows for more I/P & O/P’s.
    The reason I wanted this is I have run out of analogue I/Ps on the main board and I want to try the new functionality of closed loop control of my fuel pump. This will give me in effect a returnless PID Controller fuel system.
  • I’ve also ordered a Solid State Relay (SSR) that will be the switch for the  Pulse Width Modulation (PWM) from the MSIII. Having extra analogue I/P’s will also allow me to monitor the fuel pressure which is also used in the returnless fuel controller side of things.
  • Anyway parts and an extra wiring loom arrived today, pity I don’t have time at the moment whilst I’m frustratingly searching for a new abode.
