Someone needs to build a circuit to disable the A/C under acceleration instead of just WOT.

its called the off button

I bet you drive a manual and didn't get Navigation. And use a typewriter. And a cassette deck.

nope got all the tech stuff and in car and home and work, so now. If the A/C shut off under acceleration then it would only be on at stop lights. We are on the accelerator 95% of the time.

It's enough that our Z is not as exciting under 3k revs, but with hot oil temps and A/C on it feels like a Civic until the engine winds up past 3k RPM.

If you want better gas mileage, you shouldn't have purchased a 370Z.

I find it hard to believe you accelerate 95% of the time on public roads, and I don't think anyone besides me would use A/C on the track

I know I don't accelerate that much in my daily driver, which is mainly city driving in a small city.

well I live in TX and when not at a stop light my foot is on the gas most of the time, very little breaking really, so even if its not heavy acceleration it is acceleration and having the A/C cut out under acceleration would mean its hardly ever on. Just saying that wouldnt be a very good thing in the car, WOT is fine.

So if you need to street race you lean over and hit the little button on the dash that turns off the ac. Not really all that tough. Why is this thread 5 pages long?

Its all about getting the post count up....

Shooting for 1K...

When I drove through Texas I probably had the least acceleration of a 24hour trip - just long highways at constant speed.

I agree, but I think you guys are talking past each other. I think ZSteve means that the car is under power -- The accelerator is depressed .. e.g. not coasting.

You and others are using "acceleration" in the "physics" sense (which I think is how most people use it). When you are accelerating your velocity is increasing. So, by definition, maintaining speed on a highway is not accelerating.

I still wouldn't want my AC cutting out as I get up to the speed limit from stop light to stop light ...

so you coasted without using the accelerator thru TX?

If you werent under acceleration the car would slow down and come to a stop. WOT is fine for the cutoff but not any other time.

"acceleration" means to change velocity over time. Unless your speed is increasing you are not accelerating.

You're confusing "pushing the accelerator" with acceleration.

no not at all. If I remember right, cars today use voltage as a means of determining acceleration (along with other things too). 0 to 5v. 0 volts is only when completely off the pedal, otherwise there is some voltage between .1 and 5V that will cause acceleration, it just varies. Even on a flat road a car will require some voltage to keep the car going at a certain speed and this will cause acceleration, but you might not go faster cuz its using that voltage just to keep from slowing down due to the weight of the car and some other factors like wind. KInda like going up hill you have to give it more gas just to keep the same speed, so you are increasing the voltage to do that but not going faster. If you kept the same voltage going up hill you would lose speed.

My main point is that a WOT cutoff is fine but anything else would mean the A/C is off most of the time and as you know, here in TX we want the A/C.
