For those not willing to give up their gas-guzzling habits, Matt Vea offers an innovative alternative. Using the OBDII interface in his Jeep, a laptop, and the infinite power of Excel, Matt conducts some performance tests and uses the results to tweak both his vehicle's engine and his personal driving habits for optimal fuel consumption both on and off road." Rigorous testing and good use of available technology; nice work.
