Wideband AFR Monitoring
You will need a Wideband 02 sensor to monitor what your engine is running for fuel load, especially under boost. This will tie directly into the MSPNP2 for accurate ego control. Any wide-band will do, however AEM units are affordable, and supported well with the MSPNP2. I have found the UEGO to be a easy to install setup and it has presets in Tuner studio so all you need to is select the model you have. I am using the AEM 30-4100 for my application.
Wideband to MSPNP2 Wiring
The white wire out of the gauge harness is the wire that you need to route to the options port on the MSPNP.

Wideband Sensor Mounting
The wideband sensor should be installed at a 10deg angle, after the turbo and before the catalytic converter. Approx. 16in to 36in after the turbo will net the best results. On my setup I am not using a catalytic converter so I chose to place my wide band in the position where the converter would normally be.
