As you may or may not know, our ECU's vary engine characteristics based on whether or not it sees you pressing the brake. Just another form of control the ECU has over our driving to try to make it safer.
KPT has been beta-testing a lil module that would initially pulse the ECU when the brake is depressed so that the ECU sees that the brake input is actually working (otherwise throws a code after xx miles) and then for the length of time you keep the brake depressed, the ECU doesn't recognize it.
Without this module, the ECU maintains your RPMs OR lets you drop RPM after letting off the gas. With this module, the ECU thinks you just tapped the gas pedal and will let you rev up the full range while you're still holding steady on the brake pedal.
How is this used for us? One of two ways: you can artificially load turbos by adding the brake as a load. For example: you can be cruisin down the highway and hold the brake down a little bit while giving it gas. This loads the turbo(s) and builds boost for whenever you need it to take off and when the 3 honks (I'm not condoning street racing!) come up, you let off the brake and hammer down the gas and you instantly have boost since you were already artificially building it. This is called brake boosting.
The other way is called brake torque, which is almost the same thing except without boost. You're at a stoplight (not condoning street racing!) or at the strip with your automatic transmission car (such as the FX) and you hold down the brake while rev'in it up, then when it's time to launch, you dump the brake and slam the gas so that you're already at a more optimum RPM to launch with and use a better part of our power band when taking off.
I'll be installing it shortly.
