That is what I would think as well.

No, I didn't mean it as a question, or what I "think"..I know from experience, heh.

When I put my RE intake on, I tried it. Key off, no power to throttle cable.

Well, I assume that inside that metal casting "box" (the big box on the throttle body that the plug goes into) must have some sort of cable on it, with a motor, or something.

I was told by a Mazda service manager that there is only a need to do that when the car is cold and you don't have time to idle it.

Exactly, you want to activate the fuel cut while the engine is still spinning. Get rid of the last fuel and stop more from being injected. If you just rev it then let off, you're injecting more fuel into the engine, and that doesn't help you.

When your exhaust system is warmed up, just reving it = flames, because it injects fuel, no longer burns it, and the excess is going out unburned.


If you don't think it does anything, do it while your car is in a garage, you'll hear an audible difference.

Additionally, I've found that holding my breath while reving the car while wearing a baseball cap, also seems to help prevent flooding.

I hear the sound change, but now I'm confused as to what is causes it. When you turn off the key, the EMS is no longer doing anything, no more fuel is being injected. As this isn't carbureted, no fuel is being sucked in, either. So what exactly does depressing the gas pedal do when the car is turned off? I'm having a hard time understanding this.

So, you don't know either, I take it? That's what I gather from your post, which has nothing to do with..anything.

You turn it off when revs are decreasing so the engine doesn't add anymore fuel since the car is off and its decreasing and flushing the fuel out..

When completely off-throttle above 2600rpm, our EMS cuts all fuel to both rotors anyways..so just letting off doesn't inject more fuel alone.
