Datalog lambda values change when Kmanager is reopened

Post by Zuby »

The lambda values displayed after I complete a datalog change if I close/reopen the datalog.

The sample sizes, normal table values, and target lambda values stay the same.

I'm guessing that when Kmanager is reopened, the lambda values are being calculated a different way?

I've included the calibration, along with pictures comparing the different values displayed between exact same copies of calibration and datalogs.
If I close the initial Kmanager window that I did the datalog with, I'll never see those initial values again.

The difference was from the way the short term fuel trim was used to adjust the lambda when loading a recording. We've changed this so that the loaded recording lambda records will be the same as the datalogged values.
