DYNO-SHAFT DESCRIPTION

The AEM Dyno-Shaft is a device that measures actual driveshaft torque from yoke mounted strain gauges. This is not an inaccurate accelerometer based software

application, the AEM Dyno-Shaft provides repeatable, accurate measurement of driveline torque and horsepower.

It is unaffected by headwind, crosswinds, tailwinds, vehicle weight discrepancies, uphills, down-hills, road surface changes, wheel spin or proximity to other vehicles because the Dyno-Shaft actually measures driveline torque and RPM, it doesn’t attempt to estimate it.

The AEM Dyno-Shaft is zero maintenance. Power is supplied to the rotating sensor unit via an air-core transformer which is formed by the coil on the controller housing and a matching coil on the sensor. The sensor sends data back to the controller via the same mechanism. There are no batteries to replace and no temperamental slip rings to wear out.

DYNO-SHAFT INSTALLATION

Make sure that all the work described below is performed 100% per the manufacturer’s service instructions. If you do not have the proper tools and knowledge to perform the driveshaft work then take the driveshaft to a machine shop that can perform the work for you. Absolutely do not attempt to do this work without the proper tools as driveshaft imbalance or even complete driveline failure is a possibility.

Raise the vehicle per the manufacturer’s instructions. A vehicle hoist is probably best.

Make 100% sure that the vehicle is secure before beginning any work underneath it.

MOUNTING THE DYNO-SHAFT SENSOR

Before attempting to mount the Dyno-Shaft to your vehicle you need to check to make sure there is proper clearance to fit the device.

Confirm that at least 1.5” of your existing slip yoke’s shaft remains available outside of your transmission tail housing under all vehicle operating conditions.

If it doesn’t maintain at least this amount then do not attempt the installation.

Shortening the driveshaft or minimizing the driveshaft movement is required

before proceeding.

Confirm that there are no obstructions to mounting the controller behind the transmission tail shaft housing. Refer to the following image for reference.

Page 3 10-4800 Dynoshaft REV H

Dyno-Shaft Clearance Requirements

Once you are confident the Dyno-Shaft will fit on your vehicle you can proceed to remove the driveshaft from the vehicle.

Remove the transmission slip yoke from the driveshaft. This may be a good time to replace the u-joint with a new unit as they are a high wear item and are inexpensive. In some cases a conversion u-joint may be necessary to connect the Dyno-Shaft supplied slip yoke to the driveshaft. Compare which series u-joint your Dyno-Shaft kit is designed for against your existing u-joint to make sure you purchase the correct u-joint. The

Dyno-Shaft application guide

(http://www.aemelectronics.com/images/Dyno-Shaft_Application_Guide.pdf) lists the various Dyno-Shaft kits and their associated u-joint series.

Replace the slip yoke on the driveshaft with the supplied Dyno-Shaft yoke.

NOTE: Re-balance the driveshaft if very high driveshaft RPM (7,000+) is expected.

MOUNTING THE DYNO-SHAFT CONTROLLER

Dyno-Shaft Controller

Page 5 10-4800 Dynoshaft REV H

Before mounting the Dyno-Shaft controller, clean the tail shaft with brake cleaner or a similar solvent. Make sure the mounting surface is free from oil, debris, and casting imperfections. If the surface is painted or smooth, it is necessary to scuff the surface with 300 grit sandpaper, or similar, to allow the controller to get a proper grip on the tail shaft housing.

Example of a Clean Tail Shaft Housing

Measure the OD of the transmission tail shaft housing and select the proper adapter. All of the adapters are identical except for the inner diameter. A proper fitting adapter will have a small gap (

1

/

8

”–

3

/

16

”) when installed. Refer to the following images for reference.

Make sure the ends of the adapter are not touching, as this will prevent the controller from clamping onto the tail shaft housing.

Correct Adapter Incorrect Adapter

Place the adapter inside the clamp area of the Dyno-Shaft. The locating ribs on the adapters are designed to fit into the cavity between the clamp arms and controller body.

Page 6 10-4800 Dynoshaft REV H

Proper Fitment of Adapter In Controller Clamp with Locating Ribs Between Clamp

Arms and Controller Body

Spread the clamp on the controller and slide the controller assembly onto the tail shaft.

Orient the controller so the harness connector is at the top of the transmission. If there is a heat source nearby, orient the controller so the connector is as far away from the heat source as possible. Before tightening the clamp screw, temporarily place the yoke assembly inside the tail shaft housing. Turn the yoke and confirm the sensor can be rotated a full 360° without touching the walls of the Dyno-Shaft controller. Remove the yoke afterwards.

Insert the Yoke and Test for Full 360° Motion

Tighten the clamp screw with a

5

/

16

” socket wrench until the Dyno-Shaft controller is securely mounted. When fully tightened, there should be a small gap (

1

/

16

” –

1

/

4

”) between the clamps. Refer to the following images for reference.

Page 7 10-4800 Dynoshaft REV H

Correctly Installed Controller

Incorrectly Installed Controller, with

Incorrect Adapter

Apply a small amount of red Loctite, or equivalent, to the set screws. Using a

1

/

16

” hex tool, tighten the 4 set screws on the sides of the Dyno-Shaft controller until the controller has a proper grip around the tail shaft housing. When tightening the set screws, the set screw will pierce the adapter and mark the tail shaft housing. The set screws will rotate easily while piercing the adapter and will bottom out on the tail shaft housing when fully inserted. Tighten the set screws in a crisscross pattern to make sure the controller remains centered on the tail shaft housing.

Tightening the Set Screws / Marking on the Tail Shaft Housing

In some cases (notably some T400 and T56 Magnum tail shaft housing castings) the

OD of the housing is just slightly smaller than the ID of the Dyno-Shaft controller. In this situation no split adapter can work and a thin, flat, elastic band is supplied to shim the

OD and act as the adapter and vibration isolation.

NOTE: This is a precision electronic measuring device, therefore you must ensure that hot exhaust is not in close proximity controller. If there is a heat source near the controller you *MUST* install a shield between the Dyno-Shaft and the hot component.

Page 8 10-4800 Dynoshaft REV H

In order to protect itself, the Dyno-Shaft controller will automatically shut down when it’s driver circuit reaches 250 degF. The parameter ”Control Temp” reports this temperature and can be monitored to make sure the controller does not overheat. If the controller does overheat and automatically shutdown, it will automatically reactivate when the controller temperature drops to 165 degF. During the over temp shutdown, the controller will continue to report the “Control Temp” parameter. Parameters such as,

Speed, Torque, Power, Tank Volts, Sensor Volts, Power Level, Sensor Temp, S-Firm

Error, Zero Offset Ok, Good Cal, and LED Aligned, will stop reporting.

Reinstall the driveshaft per the mfg instructions.

Working

Area

Verify proper sensor depth

Verify that the Dyno-Shaft sensor unit on the slip yoke is roughly in the middle of the controller housing. The controller placement may need to be adjusted as excessive in/out driveshaft movement may cause the sensor signal to drop out so ensure this is correct. Also reconfirm the controller is centered within the sensor body.

At this point make 100% sure that there is no possibility the rotating sensor can contact the transmission tail shaft housing or seal under any operating conditions. Failure to do this may permanently damage the sensor!

Attach the supplied cable and route it to the monitoring device. Make sure it is routed securely, away from heat sources and moving parts. It is imperative that the plug is oriented correctly in the socket. Although it is a keyed plug, it is possible to install it incorrectly. The release tab is toward the outside of the controller. Note: Dielectric grease must be used when connecting the single row 4-pin connector on the Dyno-

Shaft controller. A suitable amount of dielectric grease is applied at the factory during the assembly process. If the harness is disconnected, it may be necessary to reapply dielectric grease before the harness is reconnected.

CONNECTING THE DYNO-SHAFT

The Dyno-Shaft uses the AEMnet electrical interface. AEMnet is an open architecture software and hardware interface based on the CAN 2.0 specification, which provides the ability for multiple enabled devices to easily communicate with each other through a single cable. The hardware connection is made through a Deutsch 4P DTM connector and contains 12 volt switched power and ground (2A max) as well as the CAN data lines. Devices connected to the AEMnet transmit data through this one connection and most of these devices receive power from this same connection as well.

The preferred connection for the Dyno-Shaft is the AEM AQ-1 Data Logger. It includes the mating connector in its harness and no wiring is required.

Page 10 10-4800 Dynoshaft REV H

CONNECTING THE DYNO-SHAFT TO AN AQ-1 DATA LOGGER

The preferred device for configuring & logging the Dyno-Shaft is the 30-2500, AQ-1

Data Logger (sold separately). This logger has been pre-configured for the Dyno-Shaft and already has the AEMnet connector preinstalled so there is no wiring required.

If using the AQ-1 Data Logger, simply connect the Dyno-Shaft connector to the AEMnet connector on the AQ-1 Harness.

Within the AQ-1 setup software, the AEMnet page is used to select what parameters are logged from the AEMnet. Devices connected to AEMnet are automatically detected and configured when the Auto Discover button is pressed.

Auto Zero – Auto Zero on or off, 1 = On, 0 = Off

Using the Dyno-Shaft

After the first few times the Dyno-Shaft is used, the sensor zero value will need to be reset as brand new yokes will twist slightly before they take a final set. You can check to see if the Dyno-Shaft needs to be zeroed by putting the vehicle in neutral, brakes off and monitoring the torque value with no load applied to the driveshaft. A typical value will be less then +/- 2 ft-lbs. Resetting the zero value is discussed in the section on

Dyno-Shaft configuration. New Dyno-Shafts can take an initial set of 100 lbs or more after the first few hard pulls but then settle down to a repeatable value quickly thereafter.

Configuring the Dyno-Shaft

The Dyno-Shaft is configured using the AEM Dyno-Shaft Configuration window. To access the configuration window, right click on the Dyno-Shaft in the AEMnet page window and select 'Config…'

Page 12 10-4800 Dynoshaft REV H

Opening the Dyno-Shaft Configuration Window

The AEM Dyno-Shaft Configuration window lists the firmware/hardware versions, as well as the zero options. The “Zero” button is used to manually reset the zero value of the Dyno-Shaft. The Auto Zero function allows the Dyno-Shaft to automatically reset the zero value on power up. Auto Zero Mode is used to turn the Auto Zero function on or off. The Auto Zero Threshold option sets the threshold for which Auto Zeroing is active. Auto Zero Threshold is a digital value in “counts”, where three counts is approximately 1 ft-lb of torque. The Dyno-Shaft will not Auto Zero if the initial torque reading exceeds the Auto Zero Threshold.

Drive Shaft Speed, where the Power and Torque will be plotted on the Y-axis vs drive

• shaft speed on the X-axis. This is the default setting.

Engine Speed, Power and Torque will be plotted on the Y-axis versus engine RPM on the X-axis. For this mode to be used either an Engine Speed channel has to be defined above or a transmission ratio must be specified. The transmission losses specified by the user will be used to correct the engine torque values.

Vehicle Speed, Power and Torque is plotted versus vehicle speed on the X-axis. For this mode to be used the final drive ratio and tire diameter must be specified.

Wheel Speed, Power and Torque is plotted versus wheel RPM on the X-axis. For this mode to be used the final drive ratio must be specified

Plot Mode Y - Defaults to "Drive Torque/Power". There are two options for the X Axis:

Page 15 10-4800 Dynoshaft REV H

Drive Torque/Power, Plots raw drive shaft torque values. These values will typically be much higher than the engine values due to the gear reduction in lower gears.

Engine Torque/Power, Plots calculated engine torque and power. Requires either an

Engine Speed log channel or gear ratio to be entered as well as transmission losses.

Smoothing - Applies a smoothing factor to the data.
