So I just ordered a few new boards from OshPark:

This was a major update which fixes all know bugs (many which are severe) and improves the protection of the circuit.

• Switch to Murata 5V switching regulator.
• LM7805 was overheating with heavy use of LED display in latest code
• Add power MOSFET for reverse polarity protection
• Add TVS diode for power/spike protection
• Fix fuel/very low fuel indicator for 03-04 and 05+
• Move EFI light off of pin 11 to allow interrupts to work
• Move Mode switch to an interrupt pin
• Add ground plane & clean up traces
• Further improve battery voltage monitoring
• Capacitors are now SMD too
