Hello! I posted a question in "technical QA" before (watch: http://www.ferrarichat.com/forum/showthread.php?t=13981), i wondered if nobody knows what kind of signal comes out of our speed sensor... As it is a common problem on our cars, anyone should have measured the signal output already?!? So please help me to get my BECKER installed.... Cheers, Alex.
I can't recall anyone posting signal waveform information for the 116987 speedometer/odometer sensor (and, unfortunately, on my TR there isn't an easy place to add a wire to measure without getting under the car), but try a search on "116987" for the threads that might have the information. Also, if you know someone else has used your navigation device successfully on another F using 116987, it most likely will work with the only difference being # of pulses per rev (but your unit is probably smart enough to learn that value).
Found this one a while back while researchin ODO issues http://www.ferrarichat.com/forum/showthread.php?t=101159
Great hit! Although it's a different sender unit on early 308 and the later QVs, it may provide the same signal devices... So i will try it out, and keep you informed! thanks, Al.
