That would be great - thanks. I'm still undecided whether I'll get better accuracy from info the car itself or from a GPS system. With data from the the car I'll encounter error due to wheel slippage - which will be cumulative. On the other hand the GPS data will have inherent absolute error problems but thanks to the U.S. military easing up on the selective availability of satellites the absolute error of the GPS data could be better than the sum of the errors from the vehicle data. Depends on the terrain, the quality of the GPS signal, H and V DOP, and whether I'm pulling data from a single constellation or accessing data and doing real-time differential correction against the Russian Glonas system. Has anyone else converted a Saab for use in a rally? If so, what do you use for telemetry information? Mark
