As you know, I'm all about DIY. I thought I'd write up a quick how to on how to log AFR's off your wideband such as an AEM UEGO. If you wanted to spend $30+ on the Busted Finger Motorsports cable, that would get you there too but I was able to create my own for less than that and this took me a total of 10 minutes to do.
This is assuming that you already have your wideband gauge installed and have already requested AccessTuner Race from Cobb here.
- A wideband AFR gauge such as an AEM UEGO, which has a serial data stream output wire. On the UEGO, it is the blue wire.
- a DB9 Female serial port connector - $5.79 on Amazon. Product linky
-serial port to USB adapter - $12.95 on Amazon. Product linky
Make sure you don't go for the cheap $3 Ebay version of the cable. You'll never be able to find the right drivers for the cable. Just buck up and spend the $13 for the cable that uses a "Prolific" chipset and you'll be fine. Don't ask me how I know this....
-soldering iron and solder
-wire strippers and some 20 ga wire. You will only need a couple of feet max of wire.
1. First you will want to assemble the 9 pin serial port assembly. You only need to solder one wire each to pins #2 and #5. See the below image. Take one 2' length of wire and solder one end to pin #2. Take another length of wire and solder one end to pin #5.
2. When you are done, it should look like this:
3. You can now assemble the 9 pin serial port case. At this point you should just have 2 wires sticking out of the port. The #2 pin wire will be connected to the blue serial cable from the UEGO. The #5 pin wire will just need to be attached to a ground.
4. Now that you've got the serial port soldered and put together, this is where the Serial to USB adapter comes in. Install the drivers for the adapter onto your laptop and plug the serial port on the USB adapter into the serial port that is running to the wideband.
5. Fire up AccessTuner Race and go to Edit > Configure Options or press CTRL+F which will take you to the Options menu. You will see a few tabs with names of common wideband gauges on them. Click on the 'AEM UEGO' tab or select the AFR gauge you are using and select the Com Port that the Serial to USB adapter is plugged into and click OK.
And that is all folks! Feel free to PM me if you have any questions!
