• Some canbus protocol data http://www.hex.co.za/vaginfo/index.html
• add can data.maby not the correct place... http://www.vems.hu/files/MembersPage/PeterJensen/can_eng.pdf
• Wary useful reading haw to control a engine http://www.vems.hu/files/MembersPage/PeterJensen/eobd_eng.pdf

Inputs - note there is a second signal to detect errors

• 2 PPS (Pedal position sensor) potentiometer mounted on the accel pedal:
• 2 TPS throttle position sensor : potentiometer mounted on the throttle body

Most likely 5V signals.

Output to drive actuator

• a variable output 0.. 12V
  • or 0..+12V and 0..-12V ? (bidirectional push-pull style? might be possible with stepper outputs, except current rating....) Can someone confirm this? 10A full-bridge driver needed. or 3A but with automatic (HW) current-sense/limit/switchoff.
    • VEMS default HW does not have 10A bidirectional outputs. H-bridge driver needed
• DC motor Driver: [TLE 7209-2R]
• DC motor Driver: [ TLE 6209-R]
• [digikey.com h-bridge] has plenty suitable H-bridges for $4..5, eg:
  • NJM2670D2 DIP22

The software/firmware to drive this is not too complex, but we experienced some lag during last months even for simple firmware tasks.

What is the current-draw ?

• Normal load: 2,5A
• Stall load 9,5A
• See the above documentation

• See all the schematic/diagram vw passat at: http://www.vems.hu/files/MembersPage/PeterJensen/el%20diagram%20alt%202000.pdf

• I got a new car VW Passat 1999 and would like to VEMS it but can we control the electronic throttle ?
  • most likely not. Any useful info about the throttle ?
• will it be possible in the near future ?
  • if you get (find/sniff/query from manufacturer) the CAN-codes (assuming it's CAN-controlled), than maybe. Otherwise not
• Or are there another way to do it ?
  • mechanical linkage (clumsy ;-)

Is the connector same as the LSU4 WBO2 connector ?
