    I'm not clued up enough on Porsches, that's why I'm at these forums where are people who can help. :) Just noted that the 964 and other porsches (C4 stuff) use a hydraulic boost pump (high pressure pump) for brakes and handle the diffs. This looked like an ideal item for another project I am on. I was wondering if anyone can describe the operation of the pump and how it fits into the who whole braking setup. Also, let me know if I am running in the wrong direction with this, but it's for removing vacuum assist for brakes. Here's a pic I found of the item. It's in the upper right, above the battery:

    Me again. Anyone have the part number for the 6-pin connector on the wiring loom that fits this throttle body connector? Or a Bosch number? To make it easier for me I might just get a VW/Audi throttle body for messing around with the PWM/PWPS and then swap the covers around in order to use a VW/Audi plug. Thanks. :)

    Ah, ok. I'm looking up servo motor control information now. Wide range of methods, some indicating 50% duty cycle to maintain position, and so on. Less than that, closes, more than that opens it. I guess now I need a similar motor to play with.

    Thanks. :) I opened it up and the potentiometers are fairly run-of-the-mill setup (carbon tracks?). I'll pull the motor as well, just held in by 2 screws anyway. Will see what the part numbers are on it and what kind it is exactly. Is that PWM constant, or is it only applied when the throttle needs to move? I ask because the motor fights against a fairly tight spring, so I assume it will be fed a constant signal to maintain position. It was indicated earlier that the input to the motor is 12V. Not being too familiar with servo or stepper motor control, may I just ask if by servo you also mean stepper motor? I will look up information on controlling servo motors, etc., online. This throttle body is quite a simple thing in construction. :) I expecting to see loads of funky stuff in there under the cover. I'll get hold of a use VW/Audi unit and experiment with that. Don't want to destroy the motor in here. Now does anyone have the wiring information for the electronic pedal? Bosch item, 6-pin as well.

    Some extra info, from MoTeC. I'll read up on their M800 and M880 to see what Aux1 and Aux2 are setup in terms of signals. Looks like 5 & 6 are outputs from the throttle body. Control must then be by 0-12V on pin 4, or a pulse-width signal. http://www.motec.com.au/drawings/x28.pdf
  6. 2226cc
    Not a problem. With the info you gave me I can try and have a chat to a local technician at Audi/VW/Bosch and see what they have on file. The late-spec VW/Audi cars use the same thing, I think, although be it in different dimensions.
  7. 2226cc
    I assume then the motor control is 12V considering the tension it has to overcome to move the butterfly valve. Is 5 an input or output?
  8. 2226cc
    That was fast! Thanks. :) Are #1 and #4 constant 12V driven (battery connection)? Or is it a range indicating throttle opening? Do you by any chance know if #3 (+5V) is constant or is that the control signal? Just trying to figure out from the diagram which pins need to be driven with which signals in order to control the valve opening. Thanks for the quick respsonse. :)

    I am looking for the pin-out information for the Bosch eGas electronic throttle body fitted to the 993/996. The part number on the unit is "996 605 115 01". Bosch part number is "0 280 750 008". The plug is a 6-pin item. Here is a picture: Also, is this connector available? From experience, Audi insist on supplying the wiring loom, but with the part number in hand for some other connector I was able to show them up and have them order the connector I needed. Can anyone hand me the part number for the connector on the wiring loom for this part?
