Yes, in my testing it did not seem to improve warm up times.

However, warm air is still a benefit to use for FE. Warm air is less dense and requires a larger throttle opening for the same horsepower output. A larger throttle opening reduces pumping losses and increases efficiency. Warmer air also increases flame speed within the combustion chamber which leads to higher cylinder pressure which improves efficiency.
