Perfect Power Application Notes. |
Application Note : AN 1.3 |
Introduction
This application note describes the various methods of tuning the CLOSED LOOP LAMBDA signal. Narrow or Wide band lambda can be tuned.Purpose
Using the SMT8, you can now tune lambda. This means you would run the lambda signal through the SMT8 for Narrow band and tee onto the signal for Wide band. When you make a change, the ECU looks at the lambda and changes itself to your new settings. The standard ECU still see lambda as correct but in actual fact the fuel settings have changed.
