AutoKontrol vs CANM8: Which Speed Limiter Is Right for You?

If you are researching speed limiters, you have probably come across both AutoKontrol and CANM8. They solve the same problem in very different ways, and the right choice depends entirely on who is doing the fitting and what the vehicle is used for. This guide sets out the difference honestly so you can decide.

The Short Answer

• CANM8 supplies self-fit, plug-in CAN-bus speed limiter kits. They are aimed at the trade - auto-electricians, vehicle converters, and installers who fit for a living and take on the calibration and responsibility themselves.
• AutoKontrol supplies EU/ECE R89 type-approved speed limiters and, in the UK, fits and certifies them for you through a nationwide mobile installer network.

Put simply: a self-fit CAN kit is a product for the trade. A professionally fitted, certified system is a compliance solution for a fleet. If you run vehicles commercially, that distinction matters.

Self-Fit CAN Kits: Good for the Trade

There is nothing wrong with a self-fit CAN-bus speed limiter kit in the right hands. For an auto-electrician or a workshop that fits vehicles every day, a plug-in module is quick, and they have the diagnostic tools, the know-how, and the professional indemnity to stand behind the job.

What a self-fit kit does not come with is the fitting, the calibration certificate, the ongoing support, or the liability. All of that stays with whoever installs it. For a trade installer, that is fine. For a transport manager, it is a risk.

Professional, Certified Fitting: Built for Fleets

A commercially operated vehicle does not just need a speed limiter, it needs a speed limiter that will satisfy the DVSA, its insurer, and the operator’s own duty of care. That is what a professionally fitted AutoKontrol system is designed to deliver:

• Type approval. An EU/ECE R89 approved device, certified by UTAC, TUV, and VCA, that passes a roadside inspection.
• A calibration certificate. Documented proof the limiter is set to the correct speed for the vehicle class, which insurers and the Traffic Commissioner expect to see.
• The fitting done for you. In the UK our installers come to your premises, so you are not sourcing a kit and finding someone to fit it.
• Warranty and technical support. A backed product and a team behind it, not a box and a wiring diagram.
• No liability on you. Responsibility for a correct, compliant installation sits with us.

What Only AutoKontrol Offers: Limiter Plus Tracking in One

The biggest practical gap between a self-fit kit and AutoKontrol is what happens after compliance. Most fleets that fit a speed limiter also want to know where their vehicles are and how they are driven. With a self-fit limiter, that means a second system and a second installation.

TrackSpeed combines a compliant, type-approved speed limiter with live GPS tracking and driver-behaviour reporting in a single unit, fitted in one visit. It is the only combined speed limiter and tracker on the market, developed with our sister brand ScorpionTrack Fleet. For fleets, that is one supplier, one install, and one set of data instead of two.

So, Which Should You Choose?

• If you are a trade installer fitting vehicles yourself, a self-fit CAN kit may be all you need, and CANM8 is one option in that space.
• If you run a fleet and need vehicles that are type-approved, certified, and ready to pass a DVSA check, with the fitting handled and the liability off your desk, professional installation is the right route, and that is what AutoKontrol is built for.

Many operators come to us after trying to manage self-fit across a mixed fleet and finding they wanted one standard, one certificate per vehicle, and one supplier to call.
