you allso need trottleposition traveled distance per amount of time wish can be done by gps or by pulses for the speedo from the car itself gps would be most acurate as tires spin

the gps only way does make more sence it can calculate torque at the roadsurface from the total weight of the car and traveled distance per amount of time , there wouldnt be anything else needed and it would be exact as long as theres traction the accuracy would depent on the amount of calculations per time (one calculation over a 1/4 mile would give an avarage torque while one every tenth of a second would give a graph of the whole run)
the torque displayed would be the torque aplied to the road from the tires , spinning tires would lower the reading as the car travels less distance , it might make a nice tool for tuning a car for traction its more acurate then seat of the pants adding trottle position hunidity and tracktemperature to it could make an adjusted graph over a complete run (it can calculate the difference to wat it would be if temperature and humidity where optimal )

this stuff gives me a headacke but i know it can be done

Ok, I think I see where my confusion is coming from. When I said I wanted to install the x86 version of Android on my VM and then install Torque, I ment the Android application called 'Torque' not to try and measure torque! Sorry for that! The program 'Torque' can estimate HP with some other factors, but it is just an estimate. I don't think it estimates torque though and that isn't a number OBDII tracks either so there isn't a way to accurately get that number from the data available. I did read a few years back, I think it was in Hotrod Mag, that some guys was trying to build a sensor that was placed on the drive shaft and would provide a the main missing piece of data to accurately measure torque without a traditional dyno... don't know where that went though.
