You do not get this transparency from log files such as intake and exhaust gas temperature, lambda, ignition, etc. Of course, these are very important parameters. From our experience, there is no way around the log files in connection with RealPower to find the optimum. Also because with RealPower they measure exactly under the conditions you will find on the road. No roller test stand can deliver the real road conditions. There you drive e.g. B. in 5th gear, the measurement up to the stop, speed 250 km / h and the test bench is in a hall where wind speeds of z. B. 120km/h can be simulated. How can these conditions match those on the road?
