Plugged into the HP Tuners MPVI1 (Multi-Protocol Vehicle Interface. input # 1 also using a ground. It does work for AFR but I need it to show lambda.

Software Configuration (VCM Scanner)
Once wired, you must tell the software how to convert that voltage into Lambda.
1.Add Channel: Open VCM Scanner, click Add Channel, and find MPVI A/D Input 1.
2. Apply Transform: Right-click the newly added channel and select Transform.
3.Select Wideband: Navigate to Oxygen Sensors > Equivalence Ratio (Lambda) or Air-Fuel Ratio.
4. Custom Linear Equation: If the Dynojet preset is not available, select Custom and enter the linear formula for Lambda.
.Lambda Formula: Lambda=(Voltage x 0.16) + 0.68
(Verify this against your specific unit’s manual).

You've just plugged in a formula with both Multiplier and Offset, as applied to the digital display of a random sample of analog wideband O2 sensor.
Running Lean how?
Lean on your displayed math- or lean in the combustion chamber?
Can you hear knock or misfire?
Check your spark plugs.
