QJMotor SRT 900 ECU TUNING (2024-2026)

2024–2026 QJMotor SRT900 ECU Tuning & Remapping

The QJMotor SRT900 is a capable adventure motorcycle powered by a 904cc parallel-twin engine, combining strong mid-range torque, long-distance touring comfort and genuine versatility for both road and adventure riding.

However, like many modern Euro 5+ motorcycles, the factory ECU calibration is designed to satisfy emissions legislation, noise regulations and global operating requirements rather than extracting the full performance potential of the engine.

At Lukos Engineering, we offer professional QJMotor SRT900 ECU tuning, ECU flashing, dyno testing and full custom motorcycle dyno calibration for 2024–2026 models.

Unlike generic ECU remapping services, we have physically tested and developed calibrations for the QJMotor SRT900 using our dedicated in-house eddy-current braked motorcycle dyno, live engine data and wideband AFR monitoring.

Our development has demonstrated measurable improvements on both standard motorcycles retaining the factory exhaust and modified motorcycles fitted with decat exhaust systems.

Our QJMotor SRT900 Dyno Results

We have carried out ECU calibration development on the QJMotor SRT900 with both factory and decat exhaust configurations.

Factory Exhaust – ECU Remapping

Our testing on the standard exhaust configuration produced the following results:

• Standard power: Approximately 95 HP
• Tuned power: Approximately 100–102 HP
• Torque improvement: Approximately 4–5 Nm

Even with the factory exhaust system retained, careful ECU calibration can improve engine performance, throttle response and torque delivery.

The objective is not simply to increase peak horsepower. By refining fueling, ignition and applicable torque-management strategies, we can improve how the motorcycle responds throughout the operating range.

Decat Exhaust – ECU Remapping

For motorcycles fitted with a decat exhaust system, our development testing demonstrated considerably greater performance potential.

Measured improvements:

• Power increase: Approximately 10–12 WHP
• Torque increase: Approximately 10 Nm
• Improved mid-range acceleration
• Stronger power delivery throughout the rev range
• Optimised AFR for the modified exhaust configuration
• Improved throttle response and engine flexibility

These gains demonstrate how much additional performance can become available when exhaust restrictions are reduced and the ECU calibration is correctly optimised.

Factory-exhaust figures are stated in HP, while the decat gains are measured in wheel horsepower (WHP). These measurements should not be directly combined or compared without accounting for the different measurement methods. Actual results vary with motorcycle specification, fuel and testing conditions.

What Can QJMotor SRT900 ECU Tuning Improve?

The SRT900’s electronic engine management system controls numerous parameters that influence performance, fuel delivery and throttle behaviour.

Factory calibrations must balance engine performance against emissions, noise requirements and worldwide operating conditions.

Professional ECU calibration can help improve:

• Throttle response and rider control
• Low and mid-range torque delivery
• Peak horsepower
• Acceleration throughout the rev range
• Fueling accuracy
• Air-fuel ratio under load
• Throttle transition behaviour
• Engine smoothness
• Performance following exhaust modifications
• Overall road and adventure rideability

For many adventure motorcycle owners, the biggest improvement is how the engine responds during everyday riding, overtaking and acceleration rather than simply the maximum horsepower figure.

Tuning With the Factory Exhaust

Not every owner wants to modify the motorcycle’s exhaust system.

Our development has shown that the QJMotor SRT900 can respond positively to ECU calibration while retaining its standard exhaust.

With measured results increasing from approximately 95 HP to 100–102 HP, the standard exhaust configuration provides an option for owners looking to improve performance without changing the motorcycle’s original exhaust hardware.

This approach focuses on refining the factory engine-management calibration to improve throttle response, fueling and torque delivery while retaining the original exhaust system.

Tuning With a Decat Exhaust

For owners who have modified their exhaust system, professional ECU calibration becomes particularly important.

Removing the catalytic converter changes exhaust flow characteristics and can affect the engine’s fueling requirements.

Our testing demonstrated gains of approximately 10–12 WHP and 10 Nm with the decat configuration and ECU tuning.

Rather than relying on a generic calibration, we can optimise fueling and engine response around the motorcycle’s modified hardware.

This service is suitable for motorcycles fitted with:

• Decat exhaust systems
• Full performance exhaust systems
• Aftermarket silencers
• High-flow air filters
• Intake modifications
• Combined intake and exhaust upgrades

Exhaust modifications must comply with applicable road-use regulations.

ECU Flash – Send-In ECU Service

Our QJMotor SRT900 postal ECU flash service is designed for customers who cannot bring their motorcycle directly to Lukos Engineering.

Simply remove the ECU and send it to our workshop. Following compatibility checks, we can install the appropriate developed calibration before returning the ECU ready to refit.

Available configurations may include:

• Standard motorcycles with factory exhaust
• Motorcycles fitted with aftermarket silencers
• Decat exhaust configurations
• Common intake and exhaust modifications

The calibration is selected according to the motorcycle’s exact specification and ECU compatibility.

For extensively modified motorcycles, a full custom dyno tune is recommended.

Dyno & AFR Health Check

We also offer comprehensive dyno testing and AFR monitoring for QJMotor SRT900 owners wanting to establish how their motorcycle is currently performing.

Our dedicated motorcycle dyno allows us to test the engine under controlled load while monitoring power delivery and air-fuel ratio.

This service is particularly useful if:

• The motorcycle has an aftermarket exhaust
• The catalytic converter has been removed
• The ECU has previously been flashed
• The motorcycle has been tuned elsewhere
• The existing calibration is unknown
• You want to verify fueling before further modifications
• You want accurate before-and-after performance measurements

Full Custom Dyno Tune

For the highest level of performance and refinement, we offer full custom QJMotor SRT900 dyno calibration.

Using our dedicated eddy-current braked motorcycle dyno, we can accurately control engine load while analysing live engine data, AFR and performance.

Rather than installing a generic calibration, we refine the ECU specifically around the individual motorcycle and its modifications.

Our custom tuning process focuses on:

• Optimising fueling throughout the operating range
• Refining ignition timing where appropriate
• Improving throttle response
• Evaluating applicable torque restrictions
• Improving mid-range performance
• Optimising high-RPM power delivery
• Maintaining appropriate AFR under load
• Verifying calibration changes through repeatable dyno testing

This is particularly beneficial for motorcycles with full exhaust systems, intake modifications or previous ECU tuning that requires correction.

Why Tune the QJMotor SRT900?

The SRT900 is designed to perform across a wide range of riding conditions, from daily commuting and motorway touring to demanding adventure riding.

A properly calibrated engine can improve the motorcycle’s flexibility and responsiveness, particularly during overtaking, climbing gradients and accelerating with additional luggage.

Our testing has demonstrated that the SRT900 responds positively to professional ECU calibration, whether retaining the factory exhaust or running a modified decat configuration.

With improvements of approximately 100–102 HP on the factory exhaust and gains of 10–12 WHP with a decat, the platform offers worthwhile performance potential.

More importantly, our calibration process aims to deliver smoother, stronger and more predictable performance throughout the rev range.
