How Recurve PWG4 Modules Work

Recurve PWG4 modules are plug-and-play tuning devices that store preloaded tune profiles for your specific vehicle. You activate the profile you want for the driving conditions ahead, switching between Stock, Balance, Towing, Power and Valet as your needs change.

At checkout you choose how many tunes are loaded onto your module. The options are 2 tunes, 3 tunes or 5 tunes. The Stock file is always included so you can reset to factory settings at any time, which is important before dealer services or warranty claims.

The PWG4 sits in Recurve's current module range alongside the IXI (USB module) and PWG3 (touchscreen module). Installation guides and training videos for each are available through the support portal.

Frequently Asked Questions

Is an ECU remap safe for my engine?

Recurve tunes are developed for specific diesel 4x4 makes and models, and the PWG4 is designed for safe and easy use by the vehicle owner. Always follow the installation guide carefully, as interruptions during ECU writing can cause permanent damage.

Will an ECU remap void my warranty?

The Recurve module stores your original factory file and lets you reset to factory settings at any time. This allows for performance enhancements without voiding your warranty, as long as you return the vehicle to stock before dealer services or warranty claims. For specific warranty advice on your vehicle, check with your dealer.

Do I need to tell my insurance company?

Yes. ECU remapping is a vehicle modification and most Australian insurers require disclosure. Failing to notify your insurer can leave you uninsured in the event of a claim. It's worth a quick call to your insurer before fitting the module.

How many tunes do I get with a Recurve module?

You choose at checkout. The PWG4 comes in three options. You can have 2 tunes, 3 tunes or 5 tunes loaded onto the module. The Stock tune is always included, plus your selection of mod files from Balance, Towing, Power and Valet. The 5-tune option includes all four mod files.

What does each tune do?

Stock keeps your original factory settings. The mod files (Balance, Towing, Power and Valet) are tuned for different driving needs, from everyday use through to heavy towing. Recurve customers report improvements like smoother power delivery, better throttle response, increased torque under load and improved fuel economy depending on the tune selected. Specific gains depend on your vehicle.

Is the installation hard?

No. The PWG4 is plug-and-play and designed for the vehicle owner to install at home. Recurve provides written guides and training videos through the support portal, and phone support is available if you need help.

Can I reset back to factory settings?

Yes. Your original factory file is stored on the module from the moment you buy it. You can reset to factory settings at any time, which is important before dealer services, warranty claims or selling the vehicle.

What's covered by the warranty?

Each Recurve module includes a manufacturer warranty for defects. Damage caused by voltage drops during tuning, improper use or ECU overwrite from a dealer update is not covered. For specific warranty terms on your module, contact the Recurve team or check the support portal.
