2. 32 PDA Dyno and OBD II Scan Tool Chapter 5 Dyno Operation Dyno operations require driving the vehicle while the Palm software records performance data For increased safety the software doesnot require user intervention during the test runs All data is recorded forlateranalysis and audible tones are used to convey instructionsto the user while driving All Dyno features are accessed via the Dyno menu bar WARNING Never race orexceed the posted speed limit while on public highways Some Dyno operations require accelerating to high speeds Use closed course raceway when performing dyno measurements WARNING Do notattemptto operate orobserve the PDA while driving a vehicle Driving requires the full attention ofthe driver Operating orobserving the PDA while driving will cause driverdistraction and could cause a fatal accident WARNING Ensure the Palm cable and interface adapter do not interfere with the vehicle controls Always ensure the Palm cable and interface adapterare securely fastened out of the way If the scan tool cannot be safely attached asto not interfere with the vehicle controls then do not drive the vehicle with the interface adapter connected to the vehicle Theory of Operation A dynamometer or dyno for short is used to measure engine power Automotive dynos are either crankshaft dynos or chassis dynos Crankshaft dynos measure the power directly at the crankshaft or flywheel a
