That is exactly how we warm up our injected car. The advantage to an injector in this case is you are putting in less alcohol so it will not milk the oil. We have now installed oil heaters in all of our cars so it is warmed to lesson how long we have to run the motor for warm-up. Running the motor rpm up when it is cold is just wear and tear it doesn't need in my opinion because the clearances are not taken up until you get some heat in the motor.
