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.
CAN2DASH by Fast Forward Automotive
The CAN2DASH converts CAN bus signals into conventional signals for older vehicles. This is useful when you are installing a 2000 model or later Volkswagen Automobile Group motor into an older vehicle that uses conventional signals for the Tachometer, Check Engine Light, EPC Light and Glow Plug Light, and Radiator Fan Control or Intercooler fan/water pump.
This CAN bus gateway is perfect for Pumpe Duse, Common Rail, 1.8T, VR6 and TFSI ECUs that do not have conventional wired outputs for:
Check Engine Light
Glow Plug or EPC Light
Tachometer - Selectable between 4 or 6 cylinders - further customization is available.
Radiator Fan Relay - On at 102/104C and off at 98/96C - further customization is available.
Intercooler Fan Relay - On only when the ECU is running.

UDS2DASH by Fast Forward Automotive
The UDS2DASH converts USD bus signals into conventional signals. This is useful when you are installing a 2016 model or later Volkswagen Automobile Group motor into an older vehicle that uses conventional signals for the Tachometer, Check Engine and Glow Plug Lights, and Radiator Fan Control, as the EDC17U64 ECU doesn't have conventional wired outputs for those circuits.

Logic Converter by Fast Forward Automotive
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.
Use Example #1: Brake Input Correction1999.5 and later Volkswagen ECUs have two brake inputs that are opposite signals from each other that must switch at the same time or else you will have an "implausible input" and the ECU will throw a check engine light. This silent solid state switch will ensure that "F" and "F47" inputs will switch at the same time and all that is required is to connect this to the brake light circuit, no additional brake switch is required.
Use Example #2: Revered Polarity Status LightsIf you have a check engine or glow plug light that uses a switched 12V input as opposed to the switched ground that the Volkswagen ECU provides, the Hasenwerk Logic Converter will resolve that problem.
Use Example #3: Oil pressure switchVolkswagen oil pressure senders go to ground when they achieve pressure, Toyota (and some other makes) instrument pods want to see the opposite signal.

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.
This is a simple, IP67 waterproof, 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.
This sender can be also used to generate a tachometer signal if you are running a full mechanical configuration, or a 2006 and later engines with no discreet tachometer signal coming from the ECU.
