30. 000 RPM to 5000 RPM in 1st gear is a shorter duration than in would be in 3 gear Therefore using 274 or 3 gear for dyno runs offers longer test durations for greater accuracy Extensive comparison testing on the Dynojet chassis dynamometer has shown the Dyno Scan for Palm OS to be extremely accurate Automatic Transmissions All automatic transmissions are equipped with a torque converter The torque converter slips under certain conditions such as at low RPM and under heavy load When the torque converter slips the gear ratio is artificially lower and the RPM higher than if the torque converter is locked up in direct drive At cruising speeds and low load requirements the torque converter locks up for increased fuel economy 43 Dyno Operation Under heavy acceleration the slippage is greatest below 3000 RPM Above 3000 RPM the slippage is still evident but to a lesser degree A slipping torque converter is perfectly normal Automatic transmissions are designed to slip which gives them some advantages when towing a heavy load However this causes an anomaly known to all the chassis dynos and the Dyno Scan for Palm OS Since the RPM is higher than normal while the torque converter Is slipping below 3000 RPM the power vs torque graphs may display an unnaturally large swell below 3000 RPM This swell is the torque converter multiplying the engines available torque The swell is normal and all dynos exhibit this behavior The

40. D Il adapter connected to the vehicle Never race or exceed the posted speed limit while on public highways The dynamometer operations require accelerating to high speeds Always uses a closed course raceway when performing dynamometer and acceleration tests Theory of Operation A dynamometer or dyno for short is used to measure the power produced by an engine Up until now automotive dynos used were either crankshaft dynamometers or chassis dynamometers Crankshaft dynos require the motor to be removed from the vehicle The power is measured directly at the crankshaft or flywheel and is not affected by transmission and axle powertrain losses Vehicle manufacturers soec crankshaft power on new cars and trucks Chassis dynos test the entire vehicle The vehicle is tied down to a large machine and the drive wheels are placed over a rotating drum The chassis dyno tests the entire 42 Dyno Operation powertrain system not just the crankshaft power This is a more realistic test since it measures the power delivered to the wheels not just the crankshaft As such the power figures measured are always less than with a crankshaft dyno since the powertrain robs some power from the vehicle Clearly pulling the motor to use a crankshaft dyno is beyond most people and chassis dynos can run 150 and hour or more to operate Auterra Dyno Scan for Palm OS The Auterra Dyno Scan for Palm OS software is a newly developed device desig
