Hardware validation means that AEM has tested a 3rd party device in house and verified that it will communicate seamlessly with the CD-7 Digital Dash. In addition to hardware-validated 3rd party devices, AEM also has manufacturer-supplied 3rd party CAN protocols for dozens of additional devices. A complete list of 3rd party applications that the CD-7 will communicate with is available on the company’s website (click the “Supported Apps” tab on the CD-7 Dash page).

A list of newly hardware-validated applications is below:

  • MEFI-4b ECU ONLY (MEFI-4 and MEFI-4a not yet validated)
  • ProEFI Pro128 ECU
  • ProEFI Pro112 ECU
  • ProEFI Pro48 ECU

The CD-7 integrates with AEMnet-enabled devices, and it includes templates with channel lists for AEMnet-enabled ECUs that speed the setup process. It works with:

  • Infinity ECUs (all Series)
  • Series 2 EMS
  • EMS-4
  • Vehicle Dynamics Module (VDM)
  • 4-Channel Wideband UEGO AFR Controller
  • X-Series Wideband Controllers
  • X-Series Gauges
  • Wideband Failsafe
  • Flex Fuel Wideband Failsafe

The CD-7/CD-7L color digital displays feature a super bright, high contrast, sunlight readable display and include an integrated glare diffuser and shade hood so that they are readable in even the brightest daylight conditions. They are designed to accept channels from CAN bus connections and do not currently include analog inputs. Two CAN bus channels are included so that it can receive and collect data from AEMnet enabled devices such as the Infinity ECU, Series 2 EMS or EMS-4, and 3rd party devices including PDMs, CAN sensor modules and programmable engine management systems.
