A Real Measurement Dyno!
Measures Actual Torque and RPM of the Vehicle
Driveline to Deliver Real Power Numbers
October 20th,
2011, Hawthorne, CA— The Dyno-Shaft is a true on-vehicle dynamometer system
that delivers Horsepower and Torque numbers as accurately as the most respected
dynamometers, with the major advantage being that it measures power while the
vehicle is under operation in real-world conditions. It is not an
accelerometer-based system, so it will not skew readings due to uphill or
downhill transitions, crosswinds, vehicle aerodynamics, wheel spin, vehicle
weight or the myriad other factors that can affect the accuracy of
GPS/accelerometer-based units. Instead, it measures a vehicle’s actual
transmitted Torque and speed at the driveshaft, allowing it to record and
output REAL Horsepower and Torque numbers.
Eliminate Guesswork at the track. Use it for engine
tuning, chassis set up and torque converter/clutch development. Dyno it all in
all conditions.
HOW IT WORKS
AEM uses a set of
laboratory-grade strain gauges inside of a supplied slip yoke to measure Torque
at the driveshaft. This is combined with a driveshaft speed sensor to precisely
measure the rotational speed of the yoke to determine RPM. The combination of
real Torque and RPM readings allows the Dyno-Shaft to output Torque and
Horsepower numbers as accurately as any dynamometer but in a more useful
setting.
The data broadcast device
(Controller) for the Dyno-Shaft yoke is non-contact, does not have slip rings,
does not require batteries and is maintenance free. This Controller installs
over the transmission tail shaft housing and allows information from the
Dyno-Shaft to be transmitted via AEMnet (AEM’s CAN-bus communications network)
to a data logger, AEM or other programmable engine management system, or custom
dashboard via a single connection.
RECORDING, READING AND OUTPUTTING DYNO-SHAFT DATA
At its core, the Dyno-Shaft
is a sensor that measures Torque and RPM and uses this data to output a
vehicle’s Horsepower and Torque in real time. You will need a ‘host device’ to record, view and output data from the
Dyno-Shaft. The following devices are capable of reading and logging data
from the Dyno-Shaft via AEMnet. The AEM AQ-1 Data Logger is the ideal recording
device for the Dyno-Shaft and also allows you to create dyno charts that can be
saved electronically for printing or digital upload.
