CAN Gateways

What is CAN Bus? CAN (Controller Area Network) bus is a modern, digital way of connecting devices in your vehicle. For example, in most 2006 and later Volkswagens, speed information is relayed to the Engine Control Unit from the Anti-lock Brake System controller via (and only by) the CAN bus. Information from the Engine Control Unit to the Speedometer is also only relayed by the CAN bus.

In order to have these newer motors function correctly, we need to convert the digital CAN signals to conventional analog signals and vice versa.

Hasenwerk CCS Korrekt (Photo coming soon)

Hasenwerk CCS Korrekt

This is a “NOT gate” or inverter circuit. When the Input is 12V the Output will be GND. When the Input is GND the Output is 12V. This is useful when you are using a 1999.5 Volkswagen Audi Group ECU that have Brake and Clutch logic “backwards” to most vehicles from the 1900s. Volkswagen ECUs have two brake inputs and they must switch at the same time or else you will have an implausible input and the ECU will no longer be happy. This silent solid state switch will ensure that F and F47 inputs will switch states at the same time and take considerable less space and than a traditional relay would!

Hasenwerk Speedometer Driver (Photo coming soon)

Hasenwerk Speedometer Driver (SOLD OUT)

This adapter will make your cable driven Volkswagen speedometer run off of a VSS signal generated by a hall sensor.

Applications for this include Volkswagen MK1 and MK2 that are converted to 02A / 02J / 02M transmissions and Volkswagen Vanagons that are converted to run on Audi quattro gearboxes.

Volkswagen Syncro owners who are running larger tires could use this in conjunction with our universal VSS to get 100% accurate speed on their speedometers.

Included in the kit is:

- Electronic controller

- Motor with machined adapter to speedometer

- Interfacing cable

Compatibility: Volkswagen, late MK1 / MK2 / Vanagon

Price: C $400 / US $300

Vehicle Speed Sensors

A Vehicle Speed Sensor or VSS is a device that measures the speed of a vehicle by reading the speedometer, CV joint, Universal Joint, drive shaft or similar rotation and converting that motion into electrical signals that read by the the engine's computer, speedometer, cruise control or similar system.

Most Volkswagen Audi Group product before 2006 want to see a speed input ratio of 1Hz to 1km/h. In other words, at 100km/h (62mph) the input frequency for a speedometer or Engine Control Unit needs to be 100Hz. 2006 and later vehicles use CAN bus to communicate speeds to the ECU.

If the VSS is going to be used to only for Cruise Control or Engine Management purposes 100% accurate speed isn't necessary as they need to know if you are moving and if so, are accelerating, decelerating or maintaining a constant speed. If you are looking for 100% accurate measurement for speedometer use then a signal calibration unit may be necessary as well.

Hasenwerk Universal VSS

Hasenwerk Universal VSS

This is a simple, IP67 water proof, universal Vehicle Speed Sensor for most vehicles with CV joints or a drive-shaft. One pulse per bolt - no external magnets are needed. This video details an example installation.
