to compute engine power/torque you could already use the speed input (when there is no tire slip), as "delta(speed/time)" should be identical to the acceleration reading (hopefully)
G reading is interesting on the 1/4mile, you can clearly see how long shifting is realy interrupting the acceleration, so the true shift-time can be calculated.
(and with the g/rpm/throttle/boost/clutch/speed a real analysis of the shift timing can be done
