Description:
The STM AEM UEGO EvoScan Serial Logging Cable allows you to directly log your AEM UEGO to your EvoScan. These work with Evolution VIII-IX-X, but may also work with other cars, depending on the logger and if it can accept external data.

These offer professionally soldered contacts and 4 feet of blue, and 4 feet of black wire to remotely mount your cable almost anywhere under your dash for easy access while logging your AEM wideband!

The STM Logging Cable connects directly to the serial output from the AEM Digital UEGO gauge/wideband. If you have a serial port on your laptop you need nothing else. With EvoScan, just check external wideband, and go to the top dropdown tab and select AEM wideband.

Includes:
(1) 48" cable as pictured

AEM Wideband Gauge Serial Cable Installation Instructions (Evo VIII-IX-X):

  1. Connect the blue wire from the AEM WBO2 serial cable to the blue "analog" wire running from the AEM UEGO harness.
  2. Connect the black wire from the AEM WBO2 serial cable with a terminal lug to chassis ground. 
  3. If you have a serial port on your laptop go ahead and attach the cable. 
  4. Go to Start/Control Panel/System/Hardware/Device Manager. Scroll down until you see the serial port listed. Right click and select advanced properties. You are going to have to set the COM port for the serial cable to COM port 3. Save and exit. 
  5. Go into EvoScan and click the Wideband tab at the top and select the correct Serial/COM port it is set up on. (There are known bugs with Evoscan when a COM port higher than 3 is used). 
  6. If you do not have a serial port on your computer, you will have to purchase a serial to USB converter, the Prolific brand serial to USB converter is a good choice. Install all software associated with the Serial to USB converter! 
  7. Connect the serial to USB converter. DO NOT CONNECT THE SERIAL ADAPTER YET! 
  8. Go to Start/Control Panel/System/Hardware/Device Manager. Scroll down until you see the serial to USB converter listed. Right click and select advanced properties. You are going to have to set the COM port for the serial to USB converter to COM port 3. Save and exit. 
  9. Go into Evoscan and click the wideband tab at the top and select the correct Serial/COM port you just set the serial to USB up on, which should be COM port 3. (There are known bugs with Evoscan when a COM port higher than 3 is used). 
  10. Connect the AEM serial cable and take a log to validate every thing is working. If you have problems, there is an excellent guide here... forums.evolutionm.net

Please Note:
If you do not have a serial port on your laptop, you will need to purchase a serial to usb adapter to interface with the gauge.
These do not work with analog wideband gauges.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
