Nology PDA-Dyno - PDA-DYNO� Works with Palm OS 3.0 or higher Provides "real world" data including powertrain losses, drag from brakes and wheel bearings, rolling resistance and aerodynamic drag Automatically adjusts for weather, altitude and different wheels/tires Easy-to-use kit turns your PDA into a complete dyno! Simply connect the PDA-DYNO� to your vehicle's OBD-II connector and turn every road trip into your personal drag strip. You'll never pay for dyno time again. Tests engine upgrades to see what they do. More accurate than a dyno. PDA-DYNO� reads the data from your diagnostic system and converts it into the same information you get from a dyno. Measures: HP and torque over the entire RPM range; 0 to 60 times; 1/8- and 1/4-mile time and speed; fuel economy (MPG). Displays: general OBD-II engine/vehicle information; Diagnostic Trouble Codes (DTC); acceleration along an entire run with detail zoom at any point; real-time sensor data (up to 2 sensors can be monitored and graphed simultaneously); values for up to 5 sensors (bar graph and analog). And it does more! PDA-DYNO� also works as an OBD-II scan tool. It can check and clear trouble codes and turn off "check engine" light. Trouble code descriptions are in plain English. It can record and store all data during a road race or a whole day at the track. Use it to monitor and record sensor values. Sensors monitored: Load Value, Vehicle Speed, Coolant Temperature, Ignition Timing, Engine RPM, Mass Air Flow, Throttle Position and many more. Want to know if your new air cleaner really is giving you more power? Just do a baseline run and record the airflow data. Then, install the new cleaner and make another run. Compare the airflow data. More airflow, more HP! Anyone can do it! Supports all generic OBD-II data: SAE J1850 (VPW, PWM), ISO 9141-2 (ISO), ISO 14230 (KWP2000) and EU-OBD-II. Complete kit includes PDA-DYNO� interface, PDA cable, OBD-II cable, software CD and manual. PDA is not included. Magnetic Windshield-mount Kit sold separately (SKU# 49ZX9317B). Limited one-year warranty. Applications: All Makes All Models, All Makes All Models, All Makes All Models
