Log Dyno Logger vs Velocity Lab Pro

Log Dyno Logger is a dedicated datalogger for Log Dyno, which measures Horsepower and Torque from your datalogs, and uses an EXTERNAL GPS device. Log Dyno Logger uses GPS devices, and datalogs speed, which Log Dyno uses to calculate back RPM from wheel sizes, gear ratios and so on. All you have to do, is select a single gear, usually 3rd gear, start datalogging, rev the car from low rpm to redline, just like you would on a dyno, let off or slow down and stop the datalogging. You can then send the datalog straight to Log Dyno for measurement. Supported GPS Devices: -PGear 610 -RaceBox Mini Originally Log Dyno was designed to work from OBD datalogs, but with high power applications, traction is an issue and causes spikes in the rpm curve, which also introduces spikes in the measurement curve. Using speed instead of rpm in the datalog ensures that the spikes are not present, even if you run into wheelspin. If you have any questions, feel free to contact me any time.
