To get both banks to be in this range, I reset the ECU through the ECUTEK ProECU app. I had the battery unplugged in the past so I’m not sure why that didn’t reset the ECU to clear previously stored trims? Maybe the ECUTEK reset procedure clears additional parameters compared to a battery-disconnect reset

Good info. thanks. I'm always looking for datalogging parameters. Haven't found much around.
