I have an arduino board which should certain be fast enough to measure timing with. Hopefully by the end of the summer I will have more time to tinker with this. As you can see in the link I want to use the GP's as a thermocouple. Using the tach sensor as a pick up to determine crank position is simply fantastic when combined with actual ignition in the cylinder.

I think your methodology has merit...Robert

Everyone @ STD has been saying that the GP are horrible thermocouplers. Why this is true I think they would give very accurate information, just not in relation to a fixed temperature scale. They should certainly help indicate timing per cylinder, graphed out the waves should be equidistant. I would really like to find a cheap alternative to the Bosch test bench. My biggest issue is measuring fuel quantity and duration. If I could do that there would be no need for the bench. One might be able to do most of the calibrations on the engine.
