So Arduino is great, and can do many good things, how about boost and afr display I thought

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 :/

i like it. what did all the part run ya?

well I already had the arduino, but I know you can get the uno and the display together for like 40 bucks?

pretty cool. Thanks for sharing!

Whats the size of the display and how does it do in sunlight? It seems a bit small to be read easily.

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 :p


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.
