What You'll Learn
Installation of the Agency Power Big Injector Upgrade
The Agency Power Big Injector Upgrade is designed for the Can-Am Maverick X3 Turbo 2017-2021 model. It is a plug-and-play injector upgrade developed in partnership with Injector Dynamics. The Injector Dynamics ID1050X Injectors are designed to boost horsepower significantly, taking the vehicle from 172HP to 235+HP. The injectors are 1065cc at 3bar fuel pressure and are designed to be used with standard unleaded fuel.
Before beginning the installation, it is important to prime the fuel system by cycling the ignition to ACC mode 2-3 times and checking for any fuel leaks.
Step 1: Remove the two T30 screws located on the fuel rail.
Step 2: Disconnect the electrical connectors from each of the three injectors. To do this, push down on the metal clip while pulling to free the connector from the injector.
Step 3: Remove the metal retaining clip by sliding it off the injector.
Step 4: Pull out the injector from the fuel rail. Gas will leak from the fuel rail during this step, so caution must be exercised.
Step 5: Install the Upgraded Big Injectors into the fuel rail and secure them using the metal retaining clip.
Step 6: Reinstall the fuel rail back into place and use the supplied USCAR to OBD1/EV1 electrical adapters to connect the new injectors.
Tuning is required to maximize the performance of the upgraded injectors. It is recommended to refer to a professional for installation and tuning to ensure optimal performance and safety.

Injector duty cycle
The duty cycle is the ratio between the pulse width required for the proper air-fuel ratio (AFR) and the length of time available to inject that amount of fuel. It is dictated by the RPM and the Otto cycle. For instance, a 20ms pulse width at 3000 RPM is a 50% duty cycle because the "window of opportunity" is 40ms. However, the same 20ms pulse width at 6000 RPM is a 100% duty cycle, as the "window of opportunity" is now 20ms.
It is important to note that the maximum available time for the injector to be open decreases with increasing RPM, which means that even if the injector open pulse width remains constant, the duty cycle will increase with RPM. For example, at 6000 RPM, the cycle time is 20ms, resulting in a duty cycle of just over 50%. At 8000 RPM, the cycle time decreases to 15ms, and if the injectors are open for the same duration, the duty cycle increases to 93.3%.
Upgrading to higher-capacity fuel injectors can help lower the duty cycle back to an optimal range, such as 75% to 80%, and provide more power.

Fuel pressure
The stock injectors on a 2017 Can-Am X3 with a stock pump have 58psi of fuel pressure, and at 18psi of boost, the available pressure drops to 40psi. The 2018 model has a slightly higher fuel pressure of 65psi. This difference in fuel pressure between the two model years results in only a small gain in fuel flow per cylinder, with the 2018 model having injectors of roughly 500cc compared to the calculated size of the 2017 injectors at 470cc.
To address the static fuel pressure issue and improve performance, some Can-Am X3 owners may consider upgrading to larger injectors, such as the Agency Power Big Injector Upgrade. These injectors are 1065cc at 3bar fuel pressure and are designed to be used with standard unleaded fuel. It is important to note that tuning is required to maximise the performance of these larger injectors.
Additionally, the fuel pressure regulator plays a crucial role in maintaining the desired fuel pressure. It is recommended to orient the fuel pressure regulator with the outlet pointing straight down and tighten the lock nut to the regulator housing. This ensures that the fuel pressure is properly regulated and maintained.
