Bosch Motorsport electronic throttle bodies (ETBs) are designed to control the fresh air delivery of spark ignition engines in combination with an electronic throttle control (ETC) system. ETB applications with flex-fuel, CNG and LPG are permissible if injected in the air flow after the throttle body. A typical ETC system includes the following components: electronic throttle body, accelerator pedal module, and electronic control unit. Additional features of Bosch Motorsport electronic throttle bodies include: * Many bore diameters available * Opening direction: most are counterclockwise; select ETBs are clockwise * Two redundant sensors control the throttle position * All ETBs have an idle air position * Temperature range: -40 to 284 degrees F (-40 to 140 degrees C) * ETBs can be connected directly to control units with ETC functionality * Supply voltage: 6 to 16 V * Supply voltage sensor: 5 ± 0.2 V * Output signal I: 0 to 5 V for 0 to 90 degrees * Output signal II: 5 to 0 V for 0 to 90 degrees

AEM Electronics Tru-BoostX gauge-type controller kits combine the simplicity of a manual boost controller with the added ease of adjusting boost levels through a gauge interface. There is no external interface required for setup and they are fully functional right out of the box. If you want more boost, press the button on the right of the gauge face, and if you want less boost, press the button on the left of the gauge face. It's that simple, and it works! AEM Electronics Tru-BoostX gauge-type controller kits contain everything you need, including an on-board 80 psig pressure sensor, built-in overboost protection with two timed shutdown levels, a scramble boost setting, and a low-side output for a warning light. AEM includes a boost control solenoid that is specifically manufactured for automotive boost applications. This means that it will not corrode and stick from exposure to rich fuel mixtures, is pressure-tested to 100 psi, and includes -4 AN fittings to eliminate any chance of leaks.

The G-Force III is the latest iteration of Go Fast Bits' feature-packed electronic boost controller—now with the ability to monitor and display your engine's air/fuel ratio in either Lambda or AFR. By connecting the analog output of most wideband oxygen controllers (i.e. Innovate LC-2, AEM UEGO etc.; sold separately) to the G-Force III's auxiliary input, you can toggle between boost pressure and air/fuel ratio display. This saves you from having to install a separate AFR gauge in your car, and it can also save your engine! A lean mixture at high boost can destroy an engine in seconds, and a stand-alone AFR gauge is next to useless when accelerating hard, as your concentration is likely to be on the road in front of you. The G-Force III safeguards your engine against a lean mixture by lowering boost to the minimum setting, and visibly warning you by flashing the display lighting. Whether your car is a daily driver or an all-out track weapon, the G-Force III has the features to tailor boost to suit your needs. Set up to six boost presets and select on the fly; use the scramble feature for overtaking, launching, towing, or protecting the engine—and you can even customize the lighting color to suit your interior! No other EBC on the market offers the features, control, ease of use, and value for money like the G-Force III! Additional G-Force III electronic boost controller details: * For boost pressures up to 50 psi (3.45 bar, 345 KPA) * Adjust peak boost, rise rate, and closed loop correction. * Display boost pressure in PSI, BAR, or KPA * 6 Boost presets, individually programmable * Unique "scramble" feature with remote switching * Peak boost recall * Air/fuel ratio display in AFR or Lambda (when connected to a wideband oxygen controller) * Separately adjustable overboost and lean mixture warning/boost cut * Touch buttons with user selectable illumination colors * Auxiliary input to switch boost presets or activate scramble * 1/2 DIN size casing, fits standard stereo slot * Supplied with MAC 3-port solenoid
