I have read a few threads be none of them seem to completely cover the topic of setting up the LM1 with the Hptuner Pro EIO. Check this out:
Right now I have my LM1 Analog Output 2 signal wired to EIO pin 1 and the Analog Output 2 ground wired to EIO pin 5 using a shielded cable and a 1/8 inch stereo plug from Radio Shack. The Ground is connected to the shield and the signal is the center conductor.
Using the LM1 software I programmed my LM1 Analog Output 2 for a 0v-5v swing where 0v is set to an A/F ratio of 10 and 5v is set to an A/F ratio of 20. Under the advanced tab I set the LM1 sampling rate to 1/6 of a second. In the Hptuner scanner I inserted the LM1 PID from the AUX list into the EIO input 1 cell.
Is this the correct way to setup the LM1 and the HPtuner Scanner for datalogging accurate A/F ratios ?
