ECU Capabilities:

First and foremost:  These ECUs are for OFFROAD use only.

We have been building and running custom ECUs for over five years.

These ECUs will come loaded with "base tune" setup for your vehicle (based on information provided by the customer).  These base tunes are usually sufficient to get the engine started, but further tuning WILL BE REQUIRED.

It is highly recommended that you also install a Wide Band oxygen sensor and the required interface for proper tuning.

Currently, we are building ECUs compatible with Speeduino firmware*.  Click HERE to learn more about Speeduino.​

• We started with the official Speeduino board layout and added some important features that make our boards more suitable for long-term installation in your project car.

• Our current offering uses a 36 pin, sealed, automotive rated connector and will include the mating, harness side housing and 40 crimp pins, so you can build your own harness.

  • We can also build you a custom harness.​

• We can also build you a plug and play adaptor harness or a full plug and play ECU that will connect directly to your factory wiring.​

• The version we currently offer supports up to four independent channels of fuel and spark control.  These have been successfully tested on a wide variety of vehicles:

  • Single cylinder two-stroke motorcycle (1978 Yamaha DT 175​)

  • V-twin motorcycle (Yamaha Road Star 1700)

  • Turbocharged Three cylinder (Geo Metro)

  • Four cylinder (Subaru EJ 205)

  • V-8 (5.3L LS)

• The firmware also has support for just about any combination you can dream up.

If you would like to add additional features, we are always willing to work with our customers to develop custom features.

We have a full eight channel version in development, and hope to be able to offer these by mid-2025

Depending on your application, you may need to add additional sensors, upgrade your fuel system, or make other modifications.  We can help that too!

We can even help you with initial startup and tuning (local customers only, for now).
