Hello there,

I'm having problems with my megasquirt build. I'm using a V3 board, and MS-II.

I have completed the input section of the build, with no problms up to now. I have come to test the inputs using megatune.

The TPS pot works fine, as does the RPM input, and the MAP input.

My O2 sensor reads at 0.28v at all times, and my temperature pots do not seem to have any effect either.

Anybody with any ideas?

Are you missing a ground or something? Double check your 'stim' and also check to see if there is 5v on the air temp and coolant temp pins on the ecu (if you can hookup JUST the powers and grounds, no inputs!). Double check your resistor values, etc. and also any soldering etc.

Good luck.
