Best Electronic Boost Controllers
Filed under: garage
Do you love the extra boost your turbocharger has, but need a good way to control your power? Electronic Boost Controllers are a great way to control how much pressure your manifold is seeing, giving you the ability to get more performance and control. Previously, the ability to control your turbocharger left you manually adjusting and switching valves and springs in mid-drive, but today technology gives you the ability to adjust without breaking out the tool kit.
There are two types of boost controllers, manual and electronic. Manual controllers are very basic and require constant adjustment and are not good for finetuning. The new electronic boost controllers provide state of the art finetuning capabilities that were previously unavailable. There are many features that these units provide that will help you create a high-performance vehicle. Once these controllers are properly installed you can use these features all from the convenience of your drivers seat.
Following we have provided you with a breakdown of how these controllers work, types of controllers, features available and some of the top products on the market today. They vary in price range and it’s important to research which products will be a perfect fit for your driving needs.
What is a Boost Controller?
Having a turbocharger can bring you that extra power that you’ve been looking for in your racer, but controlling that boost is another story. A turbocharger will give your engine more power, but even that shiny new turbocharger isn’t living up to its potential and with some adjustments can be made more powerful. Boost controllers control how much air pressure is presented to your wastegate actuator resulting in either opening or closing the actuator. To control boost you must control the spring rate on the wastegate. In the case of an electronic boost controller this is done with the addition of an air control solenoid, stepper motor and an electronic control unit(ECU). When there is less pressure on the wastegate actuator you will increase boost onset and decrease lag. The resulting effect is increased boost performance.
Types of Boost Controllers
There are two types of boost controllers, manual and electronic. Manual boost controllers are easy to install, but don’t give you the finetuning abilities and features that the new electronic boost controllers can offer.
Manual Boost Controller
Manual Boost Controllers are usually simple bleed-type pneumatic fittings. They can be cheap T-fittings installed on the boost control line near the actuator. Use of a small bleeder screw allows for adjustment. Other popular styles include ball and spring variations, that are far more preferable than “bleeder” styles, and allow for faster spooling times and less bleed out.
These controllers are generally mounted within the engine compartment and don’t allow for presets, changes(without opening engine compartment and adjustment), or data logging. Some units can be used in conjunction with electronic boost controllers.
Electronic Boost Controller
Electronic Boost Controllers are fast becoming the standard when it comes to turbocharger technology. These controllers use solenoid and/or stepper motors and ECUs to control the air pressure to the actuator. These powerful control modules use software that control the solenoid with high precision aimed at top performance. These units are mountable inside the cabin with assessible displays and controls. With a variety of options, features and abilities electronic boost controllers gives you the ultimate control over your performance needs.
Electronic Boost Controller Features
The electronic boost controllers on the market today have various designs, styles and features. Whether you are a recreational racer or a professional drag racer there’s a controller that can dial your vehicle into maximum performance. Check out the following common features the controllers feature on the market today:
To finetune your vehicles performance data logging is a must have feature for your boost controller. The majority of controllers on the market do not have contained data logging and require a separate engine management system or auxiliary data logging unit. A boost controller with data logging will enable you to setup various stages and to view boost vs. time, speed and gear. With the various data logging features of the new electronic boost controllers you will be able to setup your vehicle for the maximum performance, speed and boost.
Gear Based Boost
This feature is a wonderful ability of the new units to be able to get maximum performance for each gear. You will be able to vary the boost from gear to gear, creating a wholly unique overall boost parameter. There are some units that also allow two separate presets for gears, depending on whether you are racing or daily driving.
Speed Based Boost
Speed Based Boost is found on AEM EMS systems and is generally the most difficult boost to get dialed in. Technicalities are based in the fact that wheel spins will lend to higher, yet incorrect, speeds make the correct ratios difficult to ascertain. When the correct ratios are determined and excessive wheel spin is solved Speed Base Boost can increase gear boost with engine RPM and can lead to better traction than gear based boost.
Time Based Boost
Thisn type of boost is almost exclusively for drag racing. With the amount of variables in other driving applications like stop/go, shifting up/down and varying throttle ranges; time based boost can only be used during a situation where all the variables have already been dialed in.
Multiple Boost Levels
Many units come with multiple boost levels, allowing you to choose presets based on your current situation. Whether you are daily driving, or drag racing, you can set a preset based on the variables you have already determined is the due course. There are also options allowing you to choose between time, speed or gear boosts.
Boost Ramp Rate Control
Primarily found on the drag racing circuit, this feature allows you to increase boost with a target amount per second. This feature is found in the gear or time based boost options and allows you to specify the amount of boost applied over a certain amount of time.
Boost override allows you to override the current settings for a lower boost. For example if you are having excessive wheel spinning this feature will help you control the spinning.
