Sorry I missed this thread an all the amusing translations!
I have a speed sensor which can be fitted between the speedo cable and a Beetle speedo. It will give 4 pulses per turn of the wheel, which is close enough to correct to keep the Subaru ECU happy. You will only need to calibrate the sensors output by using an electronic speed signal calibrator if you want to use a Subaru speedometer, or possibly Subaru cruise control.
I am also currenrly working on a CV jount mounted vehicle speed signal generator for another project. It fits the 100mm diameter CV joints, and will require a speedo calibrator for all applications. One customer using a Porsche 915 in a bay is planning to use this system (when I've finished it), as he can't use the Porsche sensor for some reason.
I am not familliar with how the speedo in 911's with G50 gearboxes worked. Is there a sensor on the gearbox, and if so, what type of sensor is it? It may be possible to use such a Porsche sensor, but it may need an interface circuit and / or a speedo calibrator. If you are using a Beetle speedo and just need the speed signal to be close enough to keep the ECU happy, then the easiest way is to just fit the speed sensor between the speedo and cable: http://www.rjes.com/html/vss.html . I hope that helps. _________________ Regards,
