We developed this SpeedForSale Boost Cut Control Device, or BCCD for short, to allow the 1993-up Supra Turbo to run over 14.7psi of boost without hitting fuel cut. Unlike other boost cut control devices that are either discontinued or skew voltage output (and thus can affect other systems that reference the stock MAP sensor for operation,) our BCCD allows the voltage to pass through undisturbed until it hits the predetermined 4.1V or 4.3V. Then, it caps and holds the voltage at 4.1 or 4.3V. This allows all of your Supra's factory systems such as 9-12V fuel pump operation, turbocharger transition and pre-spool, and other things to operate like normal, but will still allow the car to run over 14.7psi of boost without fuel cut! Some additional features include:
Double side tape pre-applied. We recommend soldering these in, and therefore do not include any crimp connectors.
A red LED light is visible through the wire hole to show that the unit is functioning properly.
The instructions are the EXACT same as other boost and fuel cut controllers for the MKIV Supra Turbo, as our BCCD even has the same color wires as other popular boost cut controllers.
Very compact 1.35" x 1.35" x 0.58" case makes installing it a breeze.
