Speeduinoᴳ is the new open-source DIYᵂ engine ECU. It can run ignition-only, EFI-only or both. It can trigger COP or coil packs. It uses the Arduino Mega 2560ᴳ ($23 as of 2022) and reportedly works well☁ with many Arduino clones (as inexpensive as $13). Speeduino Australia, but also sold in USA and in England — see where to buy☁. Speeduino fully assembled is $160 (as of 2022) or $10 for the bare PCB board. Add sensors, wiring, and CPU and it's ready to go. The TunerStudio software even has an auto-tune feature if you add an O2 sensor.

Spark
<Speeduino> can use any many different types "decoders".
- Nissan Optical CAS such as RB, E15ET, CA18DET, SR20, etc. Configure Tuner Studio for "Nissan 360" decoder
- Ford-style #36-1 crank trigger wheel
Speeduino directly supports four 'smart' coils with built in igniters. No external ignitor is needed.
You can also use dumb COPs (2 pin type) by adding an ignitor module such as CA18DET ignitor or SR20 ignitor.
36-1
Ford-style 36-1 crank trigger wheel. Configure Tuner Studio for a "Missing Tooth" Decoder☁.
Use a common Ford VR sensor with a $25 add-on Speeduino VR Conditioner board.
Or, use a more expensive 3-wire Hall Sensor without needing an add-on board.
You can use Ford, Chrysler or GM twin coil packs. Or, you can use four smart (low-current) Coil on Plug units, with two pairs wired together. See Speeduino Ignition☁
Tuning
Download the free TunerStudioᴳ software.
For ignition-only, start with the basic tune file (Speeduino base tune.msq). You can further edit the VE Table, AFR Table, and Spark Tables☁ using TunerStudio. For ideas, generate a custom 16x16 TABLE using the Microsquirt toolᴳ. TunerStudio can read in an MSQ file if it's in Speeduino format.
As always, test the changed Spark Curve before driving extensively. Be sure to use a quiet exhaust system so you can hear detonation. If you have trouble hearing it — for example if your muffler is loud — use Detonation Cansᴳ.
AutoTune
O2-based autotune (Registered version of TunerStudio required).
2022 PRICES * $80 Registered TunerStudioᴳ
