Takes signal from wideband and uses a honda map sensor. Displays AFR, boost, and peak. Has a menu to adjust warning level and display brightness.
Proto board soldered up, working like a champ.
I followed the guide here
How to build a Boost and Air Fuel Ratio LCD Gauge | MyLife
but I had to change the code some to get it to work
sorry for the crappy pic :/

Thanks! Im still working on it and ill let you guys know when I get it installed, this could be a good solution for someone looking for something cheaper and who doesnt want pillar gauges ![Stick Out Tongue](https://www.miataturbo.net/images/smilies/tongue.gif)
3/4"x2" maybe? Its pretty easy to read in the day, especially since there is a bar on the screen that increases and decreases in size with AFRs, and the boost will tell you your peak, so a quick glance will tell you what you need to know.
It could be displayed on a larger screen too pretty easily.
