Random tip - cold starts

I never like starting my car "normally" after it has been standing for a few days. Due to my working environment, the BRZ sometimes stands for a few days depending on how busy I am.

The following procedure will allow the car to crank for however long you want without starting.
It will also stop the car from having that obnoxiously loud - if you have an exhaust - (and sometimes cool) high idle which is primarily used for emissions purposes to warm the cat up.

Step by step:
1. Have your keys in the car and be seated in the drivers seat (obviously).
2. Put your clutch and accelerator pedal to the floor and hold them there.
3. Hold the "Stop Start" button for however long you want the car to crank without starting.
4. Let go of the "Stop Start" button and then the accelerator and clutch.
5. Start the car normally: Clutch in and press "Stop Start"

NOTE: I have not tried this with a "standard" spec non-key-less entry car.
EDIT: Works with STD spec 86 too! (Thanks @Scarl3t !)

Benefits: The longer your car has been standing, the more oil will drain to the sump and away from the components that need it. Depending on how long the car has been standing for, a few revolutions are made with inadequate amounts of lubrication.
By cranking you car for a few seconds, you will get the oil circulating first.
Engine builders usually crank a car a few times before starting a new engine for the first time. In the aeromotive industry as well, it is procedure to crank the engine for x amount of seconds before ignition.

We enable this feature on most cars, especially race cars which tend to stand for a while between races.

The BRZ/86 has this feature build in and already enabled luckily.

Works on automatics too!

Just hold down brake and throttle pedals to the floor and crank. It keeps turning over, but won't start until you take your feet off the pedals.

Great! Thanks for letting us know!

Tried this a couple of high 30F low 40F mornings and it does seem to help with the cold start noise. Mostly the annoying overlap was decreased.

Thanks for confirming that I wasnt imagining things @Andrew025

Do not try this with an already hot engine.....
wanted to show my wife as she asked when we went for a drive why my car battles to start in the morning as i now religiously crank it a few times before starting , and failed miserably as the car revved to the limiter as soon as i turned the key.

lol

Pressing the accelerator flat while cranking the motor, cancels the injectors. I use this method when I do compression testing on my drift car and too lazy to pull off the injector pigtails.

It makes sense that you will lube up the motor.

Yeah, and helps prime turbo's too
