I have a dynojet wideband commander hooked up in my car, which is plugged in the Hptuner module. Anyone know how to convert it to read Lamdba. I tied everything I can think of including calling Dynojet themseves, they counld help.
Thanks

 

How do you have it "plugged in" to what HPT module? Details matter.

 

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).
