Moin Alex.
Direkt mit den AEM Controller kannste keine Datenaufzeichnung machen. Das weisse Kabel hat einen Spannungsausgang von 0 - 5V, je nach Lambdawert. Haste du eine orginale ECU noch drin?

Moin Marvin,

das org.Steuergerät habe ich nicht mehr drin. Ich (werde) fahre mit nen Vorläufer der Motronic B1 Ein Lambdaeingang besitzt das Stg. Dort kann ich das weiße Kabel anschliessen.
In der AEM-Anleitung steht zum blauen Kabel: *BLUE <Serial Output>
Connects to a RS-232 com port for hyper-terminal data logging.

und weiter:

Serial Output
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.
1 2 3 4 5
6 7 8 9
Figure 5. Wire View of RS-232 (DB-9) Male Plug
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.
Page 7
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. (Figure 5)
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.
Bits Per Second = 9600
Data Bits = 8
Parity = None
Stop Bits = 1
Flow Control = Hardware
Verify the settings above and click OK. When power is supplied to the AEM UEGO
Gauge, AFR (or Lambda) data will be displayed, as shown below. (Figure 6)



Also RS232 Adapter auf USB gibts ja...
