STACK's low-priced electrical auxiliary instruments feature advanced 90° air-core movements and simple 3-wire installation. Electrical sensors keep hazardous fluids in the engine compartment. White LED backlighting and illuminated needle ensure excellent readability day or night.

THE INSTALLATION OF THE AUTOMETER BOOST CONTROLLER IS RECOMMENDED ONLY FOR EXPERIENCED TECHNICIANS. THIS PRODUCT MAY DAMAGE YOUR ENGINE IF USED IMPROPERLY. THE AUTOMETER BOOST CONTROLLER IS INTENDED FOR OFF-ROAD USE ONLY OR WHERE PERMITTED BY SPECIFIC REGULATORY EXEMPTION (PLEASE VISIT HTTP://WWW.SEMASAN.COM/EMISSIONS FOR STATE SPECIFIC LAWS) IT IS THE RESPONSIBILITY OF THE USER AND INSTALLER THAT THIS PRODUCT IS USED IN COMPLIANCE WITH ALL APPLICABLE LAWS AND REGULATIONS. Offering an unparalleled feature set, the STACK Boost Controller redefines what a boost controller should be. In addition to the standard hi/lo mode, boost by RPM and boost by gear give you absolute control of your power delivery. Initial setup is incredibly simple using an intuitive menu and a evolutionary gear capture process. Configurable warnings with peak recall and boost shutdown are standard safety features designed to protect your engine. A scalable display range allows you to tailor resolution to show only the needed range for your application. STACK’s Pro Control output system is equipped to allow electric devices to be controlled at a user defined boost pressure (such as water/meth injection, nitrous, etc.) as well as Pro-Control input to default to waste gate spring pressure should the need arise. Display pressure in PSI, BAR, or kPa and easily data log and display with or without real-time barometric compensation. A direct plug wiring harness is included for ease of installation.High/Low Boost ModesEssentially two different, configurable boost settings that can be switched between with the push of a button. Perfect for the daily driver/weekend warrior, power can be called upon only when you need it striking the perfect balance between performance and efficiency. Boost By RPM/Boost By GearIntegrating AutoMeter’s most advanced digital tachometer circuit, your boost curve can be tuned precisely at 500 RPM increments to minimize wheel spin and put more power to the ground. Taking it a step further, you can even custom tailor boost levels to individual transmission gears for the ultimate in control.One Touch Gear CaptureBecause our Boost Controller looks at not only engine speed, but also vehicle speed, you can instantly capture each gear with the push of a button. Simply drive normally in your chosen gear and hit the capture button. Our advanced algorithms determine your exact gear in real time based on the ratio of these two inputs.Peak RecallOne touch recall of the highest boost pressure seen during a given time period.Configurable Warnings w/ Overboost ProtectionEasy to set parameters provide a full face warning if boost pressure moves beyond your settings. The warning doubles in speed if you pass it by 2 psi or more. The controller can also automatically return the system to wastegate spring pressure in the instance of overboost conditions, potentially averting catastrophic damage to your engine.Pro Control OutputUsing your boost measurements, the STACK Boost Controller can automatically trigger external devices such as water/methanol injection, intercooler sprayer, or nitrous solenoids at a given boost pressure level, either on the high or low end of the scale.Pro Control InputNot only will the STACK Boost Controller control external devices, it can also be controlled by external devices. Any ground signal sent to the Pro Control input will immediately back boost levels down to wastegate spring pressure.DisplayHighly versatile, boost pressure can be read in inHG/PSI, cmHG/BAR or kPa. Real time barometric compensation can also be turned on of off to account for changes in altitude and environmental conditions.Data Logger OutputIt has traditionally been a huge challenge to log both vacuum and boost. Our revolutionary approach to measurement allows for simple, configurable scale logging of both in either PSIA (absolute) or PSIG (gauge display)Tach/Speed Signal DiagnosticAs both signals are critical to extracting the most from your Boost Controller, both signals feature real time on board diagnostics to verify the presence of proper signals. Taking it one step further, if the signal is interrupted during operation, the gauge will provide a warning.A Comprehensive PackageEverything from the gauge to the wiring harness and sensor to the electronic boost control solenoid is included in the package. There are no additional pieces necessary to purchase to install and take advantage of every function with most applications.

Calibrating a speedometer isn’t a great deal of fun, but STACK’s Electronic Programmable Speedometer makes short work of the process, providing an easy to install and easy to calibrate solution that will help keep your speed exactly where it needs to be. Compatible with most factory and many aftermarket speed sensors, you will wonder why you ever struggled with a speedometer before. Calibration is as simple as a two mile (or kilometer) drive.

STACK Professional GPS Speedometers utilize the latest satellite signal technology to simplify instrument installation and accurately register vehicle speed. The included high-speed (10 Hz) omnidirectional micro antenna offers exceptional mounting versatility and eliminates the need for recalibrations associated with conventional speedometers when making adjustments to vehicle gearing or wheel circumference. Inboard configurable LED digital display indicates odometer, trip odometer, time/date, position coordinates, heading data, compass, peak speed recall, and performance meter acceleration and braking tests.
