- 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
- 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.
- 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 ;-)
The connector is : [LSU4.9 WBO2 connector] (1J0973713)
