Default DIY boost needs DIY AFR/Boost gauge

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

aaaaaaaaaaaaaaaand here is where I am at



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 :/

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

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.
