Currently using similar sensors for the throttle position.
Couldn't work out why one of the sensors was maxxing out on range, given that they are 100 degree sensors.
Spent a lot of time cursing Motec and P&G.
Got out a magnifying glass and checked the part numbers.
Yep, managed to mix up the throttle pedal (40 degrees) and throttle position (100 degrees) sensors!

Now all working perfectly. If you are short on AV inputs and have spare UDIG inputs, these sensors make a good alternative.
Definitely a lesson to be learnt here as well!
