Build your own dash

• Live gauges

  A wide boost bar with its target and the last ten seconds, and tiles for lambda, fuel pressures, wastegate duty, knock and temps, read from your DS1 over WiFi.

• Your layout

  Hold any tile to rearrange them, or change what it shows to any channel your DS1 streams.

• Tuner-grade logs

  Every drive and every pull, in the DS1's own log format, so they open in the tools tuners already use.

• Logs on your phone

  Download logs over the dash's own WiFi. No app, no cables.

• Fault codes

  The check-engine status and fault codes, with descriptions read from your own DS1.

• Ethanol blend calculator

  How much E85 and pump gas to add to hit your target.

• Graphs on the dash

  Look over a log right on the screen.

• Updates over WiFi

  New versions install from Settings.

• Map switching

  Switch your DS1's maps from the dash, with a confirm before every switch.

• Raspberry Pi 4 (2 GB or more)

  This is what SpooledOS is built and tested on.

• Waveshare 8.8" DSI touchscreen (1920×480, capacitive touch)

  The long "bar" screen. It connects to the Pi's DSI port with a ribbon cable. Other screens aren't supported by the installer.

• microSD card, 32 GB or larger

  A1 or A2 rated. A good brand matters: the car cuts the power every time you turn it off.

• DS1

  Your DS1 joins the dash's WiFi network, and the dash reads its live data from there.

• 12 V to 5 V converter, 5 A, USB-C output

  Powers the Pi and the screen from the car. Don't go smaller than 5 A: an underpowered Pi slows itself down and reboots at random.

• Add-a-fuse / fuse tap for your car's fuse box

  Lets you take power from a fuse without cutting any wires.

• Inline fuse holder with a 3 A fuse

  Protects the wire to the dash.

• 18 AWG wire, heat-shrink, crimp connectors

  For the power run.

• DS3231 clock moduleOptional

  Keeps the time while the car is off, so log names are always dated right. Without it the dash sets its clock from your phone or the internet.

• A computer, and a USB keyboard or SSHOptional, setup only

  Only needed once, to run the installer.

Gauges

Swipe or use the arrows to change page. Page 1 is boost, as a wide bar with its target and the last ten seconds, beside six tiles. Page 2 is a G-force plot beside six more. Hold any tile and they all start to wiggle: drag one to a new spot, or tap it to choose what it shows. Boost always keeps the wide panel on page 1. Tap Done when you're finished, or Reset to go back to the original layout.

Maps

The third page shows which of your DS1's maps is running. Tap another to switch to it: the dash asks you to confirm first, because a different map is a different tune. Name your maps under Settings → Map names.

Logs

The dash logs every drive, and saves every full-throttle pull as its own file. To get logs onto your phone, join your phone to the Spooled WiFi and open spooled.local/logs, or scan the QR code under Settings.

Diagnostics

Shows the check-engine status and fault codes. The descriptions come from your DS1: the dash reads them the first time the two connect, and until then shows each code on its own.

Ethanol Blend

Works out how much E85 and pump gas to add to hit your target ethanol content.

Settings

Brightness, °F/°C, time zone, map names, the DS1 WiFi network, and updates.

1. On the dash, go to Settings → Network and join your home WiFi (or a phone hotspot).
2. Go to Settings → Check for updates, then Update. The dash downloads the new version and restarts.
3. Switch back to the DS1's network afterwards from Settings → Network.

Or from a terminal on the Pi:

~/spooledos/update.sh

After the first reboot the Pi's WiFi hosts the DS1's network, so it's no longer on your home WiFi. To reach it:

• Join your computer to the Spooled WiFi, then run ssh yourusername@10.42.0.1, or
• on the dash, join your home WiFi from Settings → Network, then run ssh yourusername@spooled.local.

You can run the dash with simulated data - no Pi or car needed. With Python 3 installed:

git clone https://github.com/HybridUla/SpooledOS-Community.git
cd SpooledOS-Community
python3 server.py --demo

Then open http://localhost:8080 in your browser, with the window sized long and short like the screen.

To see what the dash is doing, run this in a terminal on the Pi:

journalctl -u spooled-server -f

• Dyno Spectrum

  For making the DS1. SpooledOS exists because the DS1 streams everything a tuned car is doing over WiFi, ready for a screen like this one to read.

• opendbc by comma.ai

  For vw_mlb.dbc. The CAN messages the dash decodes from the car's bus, and how each signal is laid out and scaled, come from it (MIT licence).

Thank you both.
