Built for Riding Communities

Are you a part of a riding community forum? If so, then we’ll work directly with you to help develop compatibility updates for your machine.


When can I get one?

Beta test kits will be available soon. If you’re interested in getting in early and helping with testing, join the forum and like us on Facebook. We’ll let you know when beta testing is about to begin!

Part 2: Can you offer dates or a more detailed release schedule?

No, development is still highly fluid and not very predictable. There are periods of very rapid progress, and other times that progress gets hung up on minor details. I don’t intend to commit to dates or a schedule. With that being said, I love the work and will continue to push forward as rapidly as possible!

If you ask for a rough time frame, I’ll answer based on my best ETA at that moment, but keep in mind that it’s an estimate and subject to change, if not completely inaccurate.

Part 3: You seem to be adding more features every update, but isn’t that just slowing down progress?
No, additional features aren’t being added before release. And the project isn’t suffering from feature creep.  New information in updates may seem to be describing an added feature, but it’s really just normal progress and maturation of the originally intended concepts.  The only big feature that wasn’t originally intended before release is the CDI ignition driver, which has been complete and ready for months.

What do the Pre-alpha, Alpha, and Beta development stages mean?

Pre-alpha stage:  The bulk of development; bench testing.  For NanoEFI, this meant building up all the separate functionality of the system, and testing these things mostly individually in simulations on the bench.  This phase is finally considered complete as of fall of 2019, when everything was tied together and  ready to be installed on an engine for further development.

Alpha stage:  On-engine live testing.

Beta stage: During this phase, a limited amount of tester kits will be offered. More information will be added soon.

What will be available from NanoEFI?

  • NanoEFI ECU, Environmentally sealed
  • Model-specific wiring harnesses, or Pigtails
  • 3-bar Fuel Pump
  • 3-bar Fuel Regulator (PWM regulation 01/05/2018)
  • Injectors
  • Sensor pack: TMAP Sensor, TPS Sensor, CLT Sensor, Fuel Pressure Sensor

(Optional) Universal Trigger Sensor
Model-specific kits will also be available which include throttle body, and additional hardware necessary for bolt-on installation.

What installation experience can I expect?

You don’t have to worry about assembling and soldering circuits, as the NanoEFI ECU will only be available fully assembled, potted, and sealed.

Will I be able to get wholesale pricing, or base a product off of NanoEFI?

Yes and Yes. The plan for wholesale pricing is coupled with a strategy for increasing compatibility across vehicles in a decentralized way.

Access to wholesale pricing will be based on your ability to develop a full kit for your intended model using the NanoEFI Core Kit.  That includes hardware and a software extension necessary to be compatible with the specific make and model that you have in mind. You must also be able to provide technical support necessary for your users.  The exception to this rule are volume-based dealers.

 Questions? Comments? Let us know your feedback.

DIY Community Vendor (No minimum quantities)
If you’re a member of a riding forum, you can get access to wholesale pricing with no minimum order volume requirements.  You must be able to develop and provide support for your users.

Developer Dealer (No minimum quantities)
More information will be coming soon.

Volume-based Dealer (Minimums apply)
More information will be coming when appropriate.

Part 2: How about exclusivity?
Exclusivity for a specific model or engine type will depend on volume.  Contact me if you’re interested.

Part 4: Will you custom develop a kit for my company’s specific application?
Yes, for a fee.  And as long as there is good alignment with the main project so it doesn’t become a detour.  Contact me if you’re interested.

Is NanoEFI hardware, software, or tuner compatible with other boards?

No.  We’re not compatible with other systems. Although I often link, refer, and encourage people to check out other projects, NanoEFI isn’t based on (or compatible with) those projects.

Who is developing NanoEFI?

My name is Travis, riding enthusiast from rural southside Virginia. I’m the owner and sole developer of NanoEFI.

Welcome to the project, I hope you’ll spend few minutes to check out the development history since 2015.

What is the best way to contact you?

On the forum, of course.

I get a lot of messages in private, mostly the same questions that have been covered in previous updates.  So to make this efficient, there’s a new process.  Please sign up on the forum and reply to a few posts that interest you.  This will help get you up to speed, and will build your trust level on the forum at the same time.  Then send me a private message when the option becomes available.  Also, upload an avatar to your account and some pictures of your machine(s) waiting for nEFI, so I know you’re serious!

For dealer or custom development inquiries only:

Please reach out to me by email.  Thank you.
