Brief history: I was using the VSS signal from my combination meter with the MPGuino but this had its drawbacks; with the ignition switch off, the combo meter shuts off as well, and that means the 'Guino thinks I'm going 0MPH. Not a huge issue though.
However, since I apparently fried my VSS sensor when I accidentally shorted it to the battery
, I'm exploring my options.
I'm interested in finding an inexpensive 'always on' speed sensor, perhaps one similar to those used on bicycles. Do they exist? Could I use one meant for a bicycle and just dial in the VSS PPMs?
I tried searching the net but nothing's turned up so far. I think I just don't know where to look.
Thanks!
