Can anyone explain to me what that "pipe temp sensing" actually does on the 440's and F5's?

Thanks!

The pipe sensor actually doesn't make heat. It senses pipe temperature and adjusts the timing curve accordingly so in effect you get the most crisp throttle under a variety of pipe temps. I think there are 5 different timing curves it chooses from. So supposedly even on a cold pipe you can get good performance. I know that on the 440 the sensor actually has some effect on the exhaust valves also. At least is't supposed to. I don't know if it effects the exhaust valves on the F5. All the sleds would benefit from this feature.
