Default Fuel trims - 01-11-2021, 04:03 PM

I noticed in all my logs that when under full throttle my fuel trims never go above 25. Reading the Honda sticky I assumed my trims should all be more than 25 (as 25 means no fuel change, 50 is +33% etc) as the ecu would need to add more fuel.

Am i misinterpreting this or is there an issue with the trims, scaling or something?

Example log attached.

Fuel trims will hover around 25 (0%), may go as low as 0 and as high as 50, and be within normal tuning range. If it runs over 50 or under 0 then it could impact the tuning and should be evaluated.
