Default fuel trims vs. timing for closed loop

Does timing change depending on LTFT value? I.e. if everything else (MAF, etc.) stayed the same, would timing change for different LTFT?

Default

timing isnt based on fuel trims rather g/cyl, ECT, IAT, OPEN or CLOSED loop, high/low octane etc. Fuel trims just tell you how far from stoich the ECM is and what the computer is doing to compensate.
