MegaSquirt Tech

  • Quick Tech Tip: MS3Pro, MSPNP, MegaSquirt and Windows XP
  • How do I power cycle or reboot a MegaSquirt?
  • Help! I broke the pins on my MS-II Daughterboard!
  • Can I use the stock IAT and CLT sensors with the MegaSquirt?
  • Using the Relay Board with the PCBv3, what do terminals S1-S5 do?
  • Where can I find the MegaSquirt Schematics?
  • I’m considering an EFI conversion – converting my car from carbs to EFI – what do I need to consider?
  • Idle Air Control Valves vs. Fast Idle Valves— What does my car have and how can I tell?
  • Is there a central place where I can download maps that others have shared?
  • The MegaSquirt 1 and 2 ECUs seem to have only four injector output pins (or terminals on the relay board) but they are labeled as pairs so this is even more confusing, do I have two or four injector outputs? And how does either two or four outputs allow me to run 6, 8, or 12 injectors?
  • Is the MegaSquirt Engine Management System just for making more power? Or can I get better gas mileage out of it too? What about emissions?
  • Sequential Fuel Injection – Do I need sequential injection to make big power? Does MegaSquirt EFI offer Sequential Injection?
  • How does a MegaSquirt compare to having my car ‘Chipped’?
