Logging values from a pressure- and position-sensors

CtCC

I need to log the pressure in a diesel-engine cylinder, as well as the position of the piston. I thought of using a halleffect-sensor to determine the position of the output shaft(three sensors, with one magnet at the shaft, so I'll get the position every 120-degrees), and I got a pressure-sensor which has an output of 0-10V, depending on the pressure. This isn't all that hard to do with just a normal I/O-card and labview or something, but I need to do this at 1000rpm, and at that speed my USB I/O-card will not be fast enough to do this. So, is this possible with basicstamp? Is it able to store, say 360 pressure-values, position values at every 120-degrees, and put it in an array together with a time-stamp at every value? (at 1000rpm :P ) I need to log 2-3 revolutions, and of course export it to a PC.

I don't know what kind of pressure-sensor you have? They vary a lot.

The cylinder pressure from the engine would be read in an average pressure @ 1000 rpms. Trying to read each stroke is
wishful thinking.(Measuring pressure is to time consuming....mechanacal hysteresis)

You'll need an A/D converter for the BS2. Since the sensor is an analog signal..

Remember the BS2 is a 5volt device, So select your A/D converter accordingly

So, that's 16.6 rotations per second (Twice as many samples). Might be tight with the BS2, but it might be possible. (Ad Warning!) If you switch to the Propeller, I wrote some datalogging code that logs variables to a USB drive. I got about 40 sps with lots of data, or 90 watching a single variable.
