Turbosmart Turbocharger Electronic Boost Controller

Turbosmart Electronic Boost Controllers: Precision Management for Forced Induction

When it comes to taking command of a turbocharged engine, few names carry the weight of Turbosmart. Their lineup of electronic boost controllers — the eBoost series — represents decades of Australian engineering expertise, purpose-built to give drivers and tuners surgical control over boost pressure from street cruisers to full-on race builds.

What separates Turbosmart's electronic boost controllers from simpler manual solutions? Programmability and precision. Unlike a basic mechanical controller, Turbosmart's electronic units let tuners map boost against multiple triggers simultaneously. As Turbosmart themselves note, electronic boost controllers offer "a host of boost settings mapped against different triggers like gear change, time, rpm or a manual switch" — a level of sophistication no manual unit can match.

The eBoost Product Family

Turbosmart's eBoost lineup offers an option for every level of build complexity:

• eBoost Street: The entry point into the eBoost ecosystem, the eBoost Street is a compact 1/4-DIN unit targeting the street performance market. It supports up to 40 psi and includes Turbosmart's unique Gate-Pressure feature, auxiliary input, and an RPM shift light option — all in a tidy, easy-to-install package.
• eBoost2: The award-winning workhorse of the lineup. The eBoost2 supports up to 60 psi (with an optional 120-psi HP version) and delivers up to six stages of boost control configurable by gear, RPM, time, or on-demand "push to pass" input. Housed in a billet aluminum gauge pod, it goes well beyond boost control — it can also manage auxiliary outputs for water spray, methanol, or nitrous injection, and monitor shift and warning lights, all in a self-contained unit.
• eBoostHP: Built for extreme applications, the eBoostHP is capable of controlling up to 120 psi, making it the go-to choice for drag racing and high-boost forced induction builds that demand headroom far beyond street use.
• eBoost3: The latest evolution in Turbosmart's boost management technology. The eBoost3 features a full-colour LCD screen and a rotating click bezel for on-the-fly adjustments. It supports single or twin solenoid setups out of the box and can monitor vital engine data like RPM, air-fuel ratio, and oil pressure from the same interface. Future firmware updates are planned to expand support for CO₂ boost control and electronic wastegate integration. Crucially, the eBoost3 is a plug-and-play upgrade from the eBoost2 — it shares the same wiring harness and mounting footprint, protecting your existing install investment.

The Turbosmart Gate Feature: A Unique Advantage

A standout differentiator across the entire eBoost range is Turbosmart's proprietary Gate-Pressure Feature. This technology manipulates the pressure signal sent to the wastegate actuator to deliver a more aggressive boost curve earlier in the rev range. According to independent testing, this exclusive feature can improve turbo response by up to 1,000 RPM earlier, meaning more power and better response without necessarily raising peak boost levels. It also eliminates wastegate creep — a common frustration in high-boost setups — for a cleaner, more consistent power delivery.

Built for Street and Race Alike

Every unit in the Turbosmart eBoost family is Australian developed, manufactured, and hand assembled. Each controller works with both boost-based internal wastegate actuators and external wastegates, making them broadly compatible across turbocharged platforms. Built-in overboost shutdown protection provides a critical safety layer, automatically cutting boost if programmed limits are exceeded — an essential safeguard for any serious performance build. Whether you're managing a spirited weekend driver or a purpose-built competition car, Turbosmart's electronic boost controllers deliver the precision and reliability that serious forced induction demands.
