CRD DIY Boost/EGT Gauge & Meth Controller

Hi All,

I'm currently deployed but had my fiance pick me up an 08 CRD a few weeks back so I started working ona little project out here.

It's a Boost and exhaust temperature gauge and water/methanol controller that I plan on mounting in one of the little cubby holes.

It uses an arduino, a max6675 thermocouple amplifier, an ads1115 analog to digital controller, GM 3 bar map sensor, and a 2.42 inch I2C blue OLED Display.

The meth turns on at 40% of max boost and rises proportionally to the boost percent,

Check it out below and if you subscribe I'll be posting lots of WK projects when I get back!

it wont let me embed since I dont have enough posts yet, go to youtube and search lWR0agWqkJA

Arduino nano clone ~$4
2.42 inch OLED I2C screen ~$26 (can use smaller ones for cheaper,$7 for 1.3inch)
MAX6675 module+thermocouple 6.99
gm 3 bar map sensor 11.99
analog-digital converter 6.99 (not necessary, just higher resolution than arduino internal)

so $30 to $56
