I just installed the ZARD UpMap Suite—which includes the T800+ control unit, diagnostic cable, and UpMap app—on my 2025 Yamaha XSR 900 GS, right after upgrading to a ZARD exhaust. Let me tell you, from the very first ride, the transformation was crystal clear.

The installation was ridiculously straightforward: I plugged the T800+ into the diagnostic port, fired up the UpMap app, selected the optimized map for XSR 900 GS, and uploaded it—all within 25 minutes in my home garage. No mechanic, no specialized tools—just smart, DIY-friendly engineering.
Out on the road, the difference is striking. Throttle response is smoother and more precise, especially through the mid-range. It now feels like the bike responds to every twist of the wrist with more intent—without being twitchy. The overall ride feels upgraded, more confident and refined in every scenario.

Best of all? That annoying “CAT” warning light is completely gone. The UpMap ECU remap is specifically designed to work with E5+ fuel and ZARD exhaust setups, preventing that nagging emission sensor warning from ever popping up.

I just completed installing the ZARD UpMap Suite on my 2025 Yamaha XSR 900 GS—after pairing it with a ZARD exhaust—and the ride is completely transformed. From my first roll, throttle response is smoother and more precise, especially through the mid‑range where I previously noticed a bit of flatness.

Getting it installed was surprisingly simple: just plug the T800+ unit into the diagnostic port, fire up the UpMap app, and upload the optimized map—it took me just about 25 minutes in my garage. No shop visits, no headaches.
Once I hit the road, the difference was unmistakable. The power delivery feels much more linear and refined, yet bolder when opening the throttle. Maneuvering through traffic or stretching out on faster roads, the bike feels more alive and responsive—without ever feeling twitchy.

Best of all? That frustrating “CAT” warning light that used to appear after installing the aftermarket exhaust is totally gone. The ECU remap smartly compensates for the absence of the catalytic converter, ensuring smooth performance in E5+ setups—no warning-light distractions.
Why this upgrade rocked:

Fast, DIY-friendly install—done in under half an hour, no tools beyond the kit required.

Noticeably smoother power delivery—especially in everyday usable mid-range.

Complete peace of mind—the remap prevents the “CAT” warning light, keeping your dash clean and your focus on the ride.

Bottom line: If you ride a 2024 or 2025 XSR 900 GS and have added a ZARD exhaust or de-catalyst, this UpMap ECU tune is a game-changer. It’s effortless to install and brings out the bike’s potential while keeping diagnostics hassle-free. Highly recommended.
