I made it to try and help with post tuning driving with the Megasquirt, to help quickly identify any glitches with the EMS / tune and maybe later keep an eye on autotuning, knock sense ignition advance... traction control... etc...
What i really wanted to implement was a rough graphing feature, so if you were driving along and felt a glitch you could (whilst taking responsible due care on the road) quickly flick through a history of key parameters to try and identify the source of the glitch. But I ran out of RAM on the display so that will have to come with a hardware improvement down the track.
Development:
Bench Testing:
Checking the temperature values:
Vehicle testing: (Sorry for the crummy videos)
