革命性创新：美国AEM发布的DYNO轴汽车测功机系统
gochinway34；） MD~NB！你有曾经在大幅的动力改装后急切想知道发动机的变化吗？这是你一定渴望获得一个测功机，看看自己爱车的发动机工况吗？ 现在借助于AEM最新发布的DYNO轴车辆测功机系统，你可以轻易获得接近真实驾驶的测试条件，并开做出相应的动力调教测试！ AEM的DYNO轴车辆测功机系统消除将消除各种动力猜测和口头马力，通过测量汽车的传动系统扭矩和转速提供真实而准确的马力和扭矩数据！它不是一个以加速度为基础的测试系统，所以它不会象GPS /加速度计为基础单位测量仪器因上坡或下坡，侧风，汽车空气动力学，车轮打滑，汽车的重量或无数其他因素就影响数据的准确性。 相反，它可以测量车辆驱动轴的实际传输扭矩和速度，并记录下真实的输出马力和扭矩的数字。
它如何工作
AEM uses a set of laboratory-grade strain gauges inside of a supplied slip yoke to measure Torque at the driveshaft. Essentially, the Dyno-Shaft slip yoke becomes the sensor for measuring driveshaft Torque. 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, and eliminates all of the inaccuracies associated with accelerometer based systems.
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.
WHAT IS AEMnet AND CAN-bus?
AEMnet is a high-speed communications system based on CAN-bus 2.0 architecture. AEMnet allows you to daisy chain AEMnet-equipped products together using a single cable to connect each device, reducing the wiring time required to add devices. CAN bus (Controller Area Network) is a single- or dual-wire serial bus protocol that connects systems and sensors and allows them to communicate.

专业文章，准确翻译很累~提供原文给大家吧，见谅！ DYNO-SHAFT SLIP YOKE (SPORTSMAN & PRO SYSTEMS)
The Sportsman slip yoke is manufactured from ductile cast iron and the splines are manufactured from a broaching process that produces industry-leading mating fit parts. Each Sportsman slip yoke is temperature compensated and individually calibrated for load through a multi-point process. The Dyno-Shaft Sportsman Series is designed for competitive amateur racers and serious performance enthusiasts whose applications can utilize a cast iron slip yoke. Professional racers with higher stress applications that require a Chrome Moly machined slip yoke will need to purchase our Dyno-Shaft Pro Series System.
The Pro Series slip yoke for the Dyno-Shaft is manufactured from Chrome Moly and CNC machined to ensure balance and concentricity. They are heat treated to ensure optimum tensile strength. The Pro Series yoke is case hardened for applications with roller bearing extension housings. The Pro version undergoes a Laboratory-Grade calibration process and receives a unique polynomial curve fit to ensure the most accurate readings across the entire Torque band. These processes ensure product reliability and accurate readings race after race regardless of operating conditions. The Dyno-Shaft Pro Series System is designed for professional racers with high stress applications that require a machined Chrome Moly slip yoke.
INSTALLATION
Installation is relatively straightforward. Users install the Controller and integrated driveshaft speed sensor externally onto the transmission tail shaft housing, then replace the factory slip yoke from their transmission with the Dyno-Shaft slip yoke.
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:
AEM AQ-1 Data Logger
The AQ-1 is the ideal host device solution for the Dyno-Shaft as it provides the broadest set of features and functionality, including:
The ability to create dyno charts which can be saved, printed or shared electronically.
The AQ-1 is a full featured data logger, so continuous power data can be recorded and replayed along with a wide variety of other vehicle information.Please visit the AQ-1 Data Logger page on www.aemelectronics.com for more information.
AEM Series 2 Programmable EMS
Like the AQ-1, the Series 2 EMS allows logging of continuous power data which can be replayed along with a wide variety of vehicle information, and has the ability to create dyno charts which can be saved, printed or shared electronically.
Certain CAN-enabled devices from other manufacturers are configured to read Dyno-Shaft data.If you do not have one of the AEM devices listed above you will need one of the devices listed below, and will need to confirm that it can read the data from the Dyno-Shaft by contacting AEM Tech Support or Sales Department at (310) 484-2322, or verifying through your authorized AEM parts supplier:
CAN-enabled Data Logger
CAN-enabled Programmable Engine Management System
CAN-enabled Racing Dash
COMING SOON—DYNO-SHAFT GAUGE
AEM’s Dyno-Shaft Gauge is a display gauge/dyno interface with basic logging capability that will allow you to view Horsepower and Torque data in real time via information transmitted from the Dyno-Shaft through the AEMnet CAN bus network. The Dyno-Shaft Gauge will feature two buttons on the faceplate for viewing peak Horsepower and Torque values, resetting peak power values, replaying dyno pulls and zeroing the Dyno-Shaft sensor.
A full-color OLED display will reside inside the center of the unit’s 52mm (2 - 1/16”) housing to provide immediate reference to power or Torque (user-selected). The gauge’s sweeping LEDs will be user configurable to display power, Torque, or boost. Illumination adjustments will allow for single value LED illumination or illumination of all LEDs up to the current value. The Dyno-Shaft Gauge will also include interchangeable faceplates and bezels to customize its appearance. Anticipated release is Q1 of 2012.

起价为1,160.96美元，真TMD值得期待！所有整套不知道10k RMB能否搞掂？gochinway16；） 说真的，我心动啦~ 看来有人对乱吹功率已经忍无可忍了gochinway03；） 大嘴怪 发表于 2011-11-25 08:59 static/image/common/back.gif
看来有人对乱吹功率已经忍无可忍了
很多人用数据来忽悠人。数据作假更害人！
不过别说~~这是真正是好DD~~~gochinway34；） 可以建议改装店都买一套。 还是木看懂……怎么玩儿～ isuka 发表于 2011-11-25 21:23 static/image/common/back.gif
