I want to include throttle position in the data that I am logging, but the 3.2L Carrera engine does not have a proper throttle position sensor (it's more like an on/off for WOT). What have others done in the older cars? I'm thinking of using one of these: http://celesco.com/promo/spseries.html connected to the throttle linkage. I figure I can also use one for steering angle.

Thoughts?

You can use a string potentiometer and a custom calibration.

sjanes

thanks. Would this also work for Steering angle (string wrapped around steering column)?

Geoffrey

yes, something like this...

I have a plunger type potentiometer under the pedal.

sjanes

Jack,

Where did you get it? Any pics?

JackOlsen

I think I got it from Race Technology (back when the dollar was a little stronger). I made an L-shaped bracket to attach to the floorboard, and then a lighter-weight bracket to hold the plunger in position under the pedal. I haven't had any issues with it since I installed it.

Seems simple enough, thanks Jack.

I got the "idea" of using a string potentiometer wrapped around the steering column from a pic I saw in a magazine. Last night I realized it was the article on Geoffrey's car in Total 911 where I saw the pic.

Sjanes,

Bosch has a local office in Ontario which it looks like your from. If you know _anyone_ with an engineering degree, they can receive free samples from Bosch directly for projects and what not.

If you don't have someone, then they I suggest a visit to a local scrapyard, if you have one that specializes in Porsche then all the better. OE sensors work great with no mods required.

Of course you can purchase retail, but I personal have a hard time paying over $300 for something that moves back an forth sending an electrical impulse.

If you haven't been the the RT forum yet, check that out as well.
