Works with single or twin turbos, and runs internal or external wastegates up to 25.5PSI. This has a high quality internal pressure sensor, and a high quality fast response boost control solenoid. The electronic boost controller (BCU+) is the first boost controller to feature multiple stages of boost, an in-built turbo timer, boost gauge, voltmeter, and two 12 Volt outputs. It comes complete with a solenoid valve. This boost controller uses the latest technology to give the user multiple ways of controlling and monitoring boost levels. Providing High and Low stages of boost and adjustable gain, the boost can be tuned to switch depending on track or road conditions. The BCU+ also incorporates an Automatic and Manual Turbo Timer to let your engine cool down after a run. By using the electrical Outputs, you can use the BCU+ to control any 12V DC source, like a nitrous kit and/or intercooler spray. Know exactly what's going on with your engine by using the Last Boost and Voltmeter settings on the easy to read LCD screen. Multiple stages of boost (two stages) Built in turbo timer (auto and manual) Boost Gauge Voltmeter Two 12 Volt outputs BCU+ uses the latest technology to give the user multiple ways of controlling and monitoring boost levels. With High and Low stages of boost and adjustable gain, you can tune the boost to switch depending on track or road conditions. The BCU+ also incorporates an Automatic and Manual Turbo Timer to let your engine cool down after a runb by using two electrical Outputs, you can use the BCU+ to control any 12V DC source, like a nitrous kit and/or intercooler spray. Know exactly what's going on with your engine by using the Last Boost and Voltmeter settings on the easy to read LCD screen. The Turbo Timer has both Automatic and Manual settings. This allows the user to manually set how long the vehicle should continue to run after the key is removed from the system. Or, for an even easier setting, allow the BCU+ to calculate exactly how long your engine should run based on how much boost the engine has seen. The Switching System is a great feature for drag racers! The BCU+ has the ability of controlling any 12v accessory based on the following criteria: Boost Level Boost Level Manual Timer Automatic Timer Limit Feature Warn Feature Start Boost Setting This means you can control a nitrous system based on boost levels! This, however, is not the only option. Any electrical component, from LEDs to intercooler sprayers can be controlled by the BCU+. Please see the Optional Wiring Section of this installation manual for detailed information. Compact Design The BCU+ comes in a 4.17" x 4.65" x 1.1" compact design and uses on the the smallest solenoids around for an easier installation both inside the car and under the bonnet. Information Display The BCU+ has an LCD screen so that all the functions and settings can be viewed. Boost Setup Two different boost levels can be easily setup by turning the Hi and Lo knobs Safety The BCU+ has multiple safety features. Over boost - The LCD background display will turn red and an audible alarm will both warn the driver if over boost occurs. Limiter - The BCU+ has limiter which will limit the amount of overboost by modifying the opening of the solenoid based on the preset limited % and preset boost. Turbo Timer The BCU+ has a manual and automatic turbo timer. The manual timer allows the engine to run for a specified time adter the key has been removed from the ignition; and the automatic timer allows the engine to run for a certain amount of using voltage variation once the key has been removed from the ignition. Channel Outputs The BCU+ boost controller can be programmed to activate and deactivate electrical components when certain specified criteria are met. Complete Kit Vacum tube, cables and solenoid valve are all included.
