It looks to be RS-232, output only, so I should be able to get it to work. Do you have any info on the serial format? Do you have one I can borrow, or do you know if the gauge only version still has the RS-232 (it appears to be cheaper)?

I don't have any information on it, but if you tell me what I could do to capture it, etc., I don't mind doing it. Unfortunately, mine is pretty integrated into the car right now, it would be a bit of work to remove it.
Both the Gauge Included and Inline (No Gauge) UEGO seem to have the same connections, so I imagine they are similar.
This is the data from the Manual:
- Code: Select all
Serial Output (optional)
The serial output can be used for data logging when an EFI system is not accessible. To run the data stream, a RS-232 (DB-9) Female Receptacle shall be purchased.
Two wires need to be connected to a RS-232 serial port. The BLUE wire from the AEM UEGO Gauge shall be connected to Pin #2 (RX) on the serial port for receiving data. Pin # 5 (GND) on the serial port shall be grounded. If a standard 9-pin serial cable is to be cut instead, the (RX) wire is typically RED and the (GND) wire is typically GREEN. However, this should be confirmed with a continuity tester before attempting.
Use HyperTerminal for testing the data stream. This software is found on most PCs. To find HyperTerminal go to: Start | All Programs | Accessories | Communications | HyperTerminal.
Name the New Connection and click OK. Set the COM port to the one being used and click OK.
