PRODUCT SPOTLIGHT: GET SX1 PRO 4T ECU
How to unlock the full potential from your fuel-injected four-stroke engine with GET’s new SX1 PRO 4T ECU.
A couple of week back, when we showcased the GET SX1 PRO 2T ECU – the first replacement ECU for the latest generation of fuel-injected two-stroke engines – we answered the first question that seemed to be on people’s lips when they initially lay eyes on this all-new GET product: “How can an Italian electronics company produce aftermarket ECUs that upstage what the manufacturers make for their own bikes?” The answer: to comply with global emissions regulations, motorcycle engines are often tuned for lower emissions rather than maximum engine performance. Hence, OEM manufacturers adjust and set the motorcycle’s ECU parameters to meet certain standards – whether we’re talking two-strokes or four.
The good news is that that leaves room for performance gains; an opportunity that GET – the electronics division of the Athena Group and the world’s leading aftermarket Engine Control Unit (ECU) manufacturer for more than a decade – has taken full advantage of. This is GET’s take on a series of frequently asked questions about its all-new SX1 PRO 4T ECU and performance accessories…
What is GET’s solution to unleash your engine’s untapped potential?
Without the right knowledge, remapping or ‘reflashing’ your existing ECU can prove to be a difficult and costly exercise. The GET SX1 PRO 4T ECUis professionally tuned to maximise engine performance and instantly unlocks the full potential of your stock four-stroke injection engine. Just plug and play. The SX1 PRO 4T ECU unit is available for all new-generation (2023-2024) KTM, Husqvarna, GASGAS, Honda, Yamaha and Kawasaki models. Each offers two bespoke maps that are developed to suit each make, model and engine capacity. GET engineers programmed multiple ECU parameters to optimise performance and reliability across the entire power curve.


What steps has GET taken to produce the SX1 PRO?
GET is a trusted brand by many Original Equipment Manufacturers (OEM) and strongly involved in the OEM market by offering a complete service of both electronic software and hardware solutions. It’s through these partnerships that GET has developed, tested and verified product performance. GET boasts an experienced team of engineers and technicians who’ve devoted their time to ensure performance and reliability of the all-new SX1 PRO 4T ECU. To tune the latest generation four-stroke injection engines, GET engineers programmed multiple ECU parameters to optimise performance across the entire power curve. And this results in two pre-loaded maps for instant plug-and-play performance gains.
How does the SX1 PRO 4T ECU improve my new four-stroke?
You’re essentially upgrading the brain of your motorcycle and unlocking key parameters of the engine. The Engine Control Unit (ECU) serves as the technological heart, orchestrating a myriad of functions that are critical for optimal engine performance. The ECU adjusts aspects such as air and fuel mixture, ignition timing, and throttle response – all based on data received from various sensors throughout the bike. By upgrading to the GET SX1 PRO 4T ECU, you achieve significant improvements in power, efficiency and responsiveness.

Are the maps different across makes and models – a 450EXC-F vs a CRF250R, for example?
Yes, each SX1 PRO 4T ECU offer two bespoke Map selections that have been developed extensively to suit each make and model. For example, GET developed an ECU package for the all-new CRF range with Team Honda HRC and verified the performance with team riders Jett Lawrence, Hunter Lawrence and Tim Gajser for the 2023-2024 seasons.
What are the two pre-installed maps?
Map 1 (“Racing”) is configured for full power while Map 2 (“Wet”) is configured for smooth power delivery on wet and slippery conditions. Unique to the SX1 is the ability to switch between Map 1 and Map 2 on the fly using the SX1 Handlebar Controller. For each map, riders can activate GET’s patented GPA Traction Control technology and launch control system for racing.

What is the ‘GPA Traction Control’ system and how does it work?
GPA stands for ‘GET Power Assistance’ and is a sophisticated electronic system built within the SX1 ECU that ensures optimal traction in various riding conditions. To maintain traction in hardpack or slippery conditions, the GPA makes real-time adjustments to the engine’s power development when it detects rear wheel slip. This is achieved by analysing a huge amount of data and adjusting parameters – such as throttle response, ignition timing and fuel injection. You can adjust the level of GPA Traction Control in real-time using the SX1 Handlebar Controller.
Can the ECU detect changes in altitude?
Yes, the SX1 PRO unit features a Barometric Pressure Sensor (BPS) that measures the atmospheric pressure outside the engine to analyse changes in altitude (atmospheric pressure decreases with increased altitude). This measurement is crucial for adjusting air and fuel mixture and ignition timing.
Can the ECU integrate with my external cooling fan?
Once your motorcycle is connected to the WiGET app, you can activate and set up your radiator cooling fan. Inside the WiGET app, you can activate your fan to your desired temperature level. This is the temperature at which the radiator fan will turn on to cool the engine.
Can I accidently tune my engine to unsafe levels?
The WiGET device app is designed to allow you to adjust the engine settings and other performance parameters easily and conveniently. Parameters within the app are pre-set and won’t allow you to unsafely tune your motorcycle. GET engineers and technicians created pre-set configurations which are tested for safe operation. The app restricts the range of adjustment within these parameters to prevent users from making extreme changes that could damage the engine. The WiGET app provides real-time data monitoring (when stationary), allowing you to see the impact of your adjustments immediately.

When GET claims its ECUs allow me to extract more from additional modifications, what do they mean?
According to GET, “Upgrading to a GET engine control unit should be the first performance upgrade you consider because it offers a foundation that amplifies the effectiveness of other performance upgrades. Hence, starting with an ECU upgrade will instantly improve performance and help extract more from additional modifications.” In other words, the overall performance gains created by things such as adding a Powerflow Kit to increase airflow, increasing compression, or changing gearing ratios to suit riding conditions is all amplified by the GET SX1 PRO 4T ECU.
How much is a GET SX1 PRO ECU, and what’s included?
The GET SX1 PRO 4T ECU retails for $1499.95 AUD, which includes the super-trick SX1 Handlebar Controller, SX1 Connect (WiFi) and WiGET application.
