FOR IMMEDIATE RELEASE
AEM Releases the Dyno-Shaft On-Vehicle Dynamometer System —
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.
MSRP ranges from $1,600.00 to $2,100.00 by application, including an AQ-1 Data Logger. Please visit http://www.aemelectronics.com/dyno-shaf ... e-dyno-73/ or call (310) 484-2322 for more information or to find an Authorized AEM Electronics dealer or Factory-Trained tuner.
