In my first car, a Alfa romeo 155 it worked flawless. Now in my Alfa romeo 75 I cant get a good VSS signal?.
Up until 20-40km/h MPGuino actually shows the speed, but then goes the oppesit way down to Zero beyond that speed??.

I had this problem with my home built VSS. I have a corroplast disc clamped to my driveshaft, with an LED and an IR photosensor reading light pulses through slots in the disc. However, with 4 slots in the disc my MPGuino would do what you described, starting at 35 mph. I covered 2 slots and it worked until 75mph. I only run one slot now, as some highways have an 85mph speed limit.
Just need to get a reliable IR sensor installed...
