Yes, but if the moment of full throttle was longer than 0.1sec, there would be a throttle fault, and it would disable the throttle. Even though this sounds like it could be pretty common, I've never heard of a throttle doing this in all the 5 years. I don't mind using a hall effect sensor. I've used a 0-5k pot default in the past because that's just what most people had (the curtis pb-6). It also made debugging easy, since I could just go get a $2 pot at radio shack. It was also easy to detect throttle faults. If the throttle line broke, it would go to infinity, which would be out of range, which would disable things.

The other concern I have is the signal being from 0v to 5v. At the moment, zero throttle is like 1.5v, and full is 3.5v (or vice versa), which protects the port from being close to 0 or 5v. 0v with noise would push it to the dreaded -0.6v (or 5.6v). The poor little diodes on the port have to conduct to prevent that. I know Damien has used one for some time. I'm sure they are fine. Those are just the thoughts running thru my head. Let me check out the hall effect throttle... brb.

Wow! That looks simple. Are they available outside of australia? It seemed like Damien's had 10 wires or something. I could be wrong.
