General Info
These are no longer for sale… but now they are free to DIY!
Download the files for your kit. Sheet Metal Parts can be sourced from sendcutsend. There are many willing and able 3d printing companies to make the bezel for you. Feel free to reach out to me for 3d printing as well, I can make one and send it to you. $25 US or $30 International.
If you like your kit, you can buy me a coffee :) This website is not free, and I spent a lot of time designing and protyping, so please pay whatever you think the kit is worth! If you think it’s worth nothing at all, that’s fine!
This project requires very basic soldering, coding, engine tuning (if showing live engine data), and a LOT of googling. As an engineer that doesn’t work much with computer systems, I had to teach myself these things, and I’ll provide you some resources where you can learn.
This is not the only way to build it - this is just how I set mine up

You may find a better way to do things. Please let me know if you have improved upon this so I can update my system and update this guide! Any feedback/criticism is greatly appreciated.
Requirements for installation:
These are items that you need to install/obtain/learn prior to installation of the screen housing. Links to any physical components are included.
Little to moderate experience with coding in Linux & python
Little to moderate experience with wiring & soldering
Aftermarket ECU (I use a MegaSquirt MS3. This feeds the raspberry pi the live engine data)
1990-1993 (NA6) or a 1994-1997 (NA8) Mazda Miata (or a later model with a dash conversion.
Raspberry pi 7” official touchscreen display (versions 1 and 2 are both compatible)
2x 2-1/16” Standard Gauges or block-off plates
Mausberry Circuits Car Switch / Power Supply (soft shut-down & 5v power for raspberry pi)
A headless dual-channel amp to run your sound system, small enough to tuck behind the switch plate (optional)
A good soldering Iron

ECU INFO
Greg Peters from TheCarPassionChannel on youtube has way more info in a much more clear and concise format than I could ever produce. Watch all of these videos. Thrice.
OGPedexing also has a ton of info on his youtube channel. Watch these 3-4 times for good measure
The megasquirt has a DB9 output port. A DB9-to-USB cord sends data to the raspberry pi to show live engine data. Live Engine data is displayed on a program called TunerStudio.
I would highly recommend the paid version of TS, as you gain the “autotune” feature, which is immensely useful while setting up your base tune.
RASPBERRY PI INFO
TunerStudio has an option to launch dashboard mode on program startup.
Go to Options -> Advanced -> then select “Load Last Project on startup” and “Make Dashboards full screen”

Sean Wally - uses a Miata with tuner studio - very helpful & Specific
