Polaris RZR Ranger 570 800 900 1000 Turbo Pro XP ECU ECM Premium Tune Service

Description

APEXSPORT PRECISION TUNING

Most tuning companies sell preloaded “canned” maps — one-size-fits-all junk that runs rich, knocks timing, and leaves power on the table. APEXSPORT doesn’t do that. Every APEXSPORT ECU tune starts from your actual stock ECU file, then gets rebuilt line by line to match your specific machine, setup, and riding style.

This is true calibration — not a copy-paste job. Our tuning engineers use the same principles we apply in our engine building division, where we’ve built some of the strongest UTV and ATV engines in the country. The result is smooth, predictable power, massive throttle response gains, and real-world reliability.

When you purchase a tune please send the following information to our SUPPORT so that we can ensure your custom tune is the best it can be:

• Full Name
• email and Phone Number
• Your Year, Make and Model
• Which Tune Stage you Want
• List all Current Upgrades You’re Currently Running on Your Machine

HOW IT WORKS

1. Order Your Tune.

2. We ship you an APEXSPORT TDN Device + Link Cable.

3. Plug into your machine and download the TDN App.

4. Hit “Read Vehicle.” The app automatically sends your stock file to our tuning department.

5. Within 24–48 hours, we’ll send your custom tune back.

6. Flash your ECU, start it up, and feel the power.

APEXSPORT PRICING

WHAT MAKES APEXSPORT DIFFERENT

• True Custom Files – We don’t modify generic templates; we rebuild your ECU file using HP Tuners’ latest software.

• Performance + Reliability – Our calibrations deliver power you can actually use — without risking detonation, lean spots, or overheat issues.

• Factory-Level Control – Throttle, torque, fuel, timing, cooling, limiters, and idle logic are all rewritten from scratch.

• Fast Turnaround – Tunes are built and returned within 24–48 hours.

• Backed by Engine Builders – Nobody knows Polaris, Can-Am, and Yamaha calibration limits better than the people who build and warranty them.

STAGE OPTIONS

STAGE 1 — +5–10 HP

For: Stock or lightly modified machines

Ideal Use: Trail / Utility / Everyday Riding

Includes:

• Sharpened throttle response

• Cooler fan activation temps

• Increased speed & rev limiters

• Raised torque limits

• Optimized fuel and ignition maps

• Smoothed throttle transitions

Result: Instant throttle feel, stronger midrange pull, cooler temps, and better drivability — without stressing the engine.

STAGE 2 — +10–20 HP

For: Machines with a slip-on or full exhaust system

Ideal Use: Performance Trail / Dune / Desert

Includes:

• All Stage 1 features

• Lower cooling fan temps

• Removed seatbelt & speed limiters

• Adjusted misfire detection for smoother decel

• Enhanced timing & fueling for high-flow exhaust systems

Result: Aggressive throttle response, stronger top-end, no more factory restrictions — it feels like a completely different machine.

STAGE 3 — 20+ HP (Build-Dependent)

For: Big bore kits, cams, turbo systems, or full engine builds

Ideal Use: Race / High Performance

Includes:

• Fully custom tune built from your ECU data

• Optimized fuel, timing, and torque tables

• Boost-safe ignition calibration (for turbo builds)

• Custom AFR targets & injector scaling

• Individualized torque model tuning for each build

• Optional data-log review and fine adjustment

Result: Peak power and precision that matches your exact build. Built for real race power, not dyno hype.
