THE DETAILS ON ALL FEATURES

• FUELING -  With custom tuning we can target better AFR (air/fuel ratio) plots to enhance not only racing performance, but also cruising and partial throttle inputs.
• IGNITION - Optimized to make the most power while still being safe and reliable.
• THROTTLE DERESTRICTION - Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has a “dead spot” on the top end that kills the bike's power curve when it should be making the most. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline.
• QUICK SHIFTER - We all know how slow the QS is stock. Our flash provides 50% shorter quick shifter up and down. Our tuning reduces "kill" times to make the quick shifter much faster than stock, and a better overall riding experience.
• LOWER FAN-ON TEMP - Let’s face it, this bike rides a little on the hot side. To help not only the rider's enjoyment but also to keep the engine slightly cooler, we've lowered the fan-on temps.
• INCREASED RPM LIMITER (at customer request) - The stock RPM limiter is set to 13,800 RPM. We have been testing 14,200 RPM with zero negative side effects. We set the RPM limiter for 14,200 RPM in all gears. This helps you stay in the powerband longer and reduces the need to shift at the track.
• INCREASED TOP SPEED LIMITER - Removed so you can let the bike run free in any track environment.
• EXHAUST VALVE MANAGEMENT - Improved and optimized for peak performance and sound
• RACE FEATURES - Minor features unlocked for the purpose of track use
• FUEL CUT - Optimized for better limiter feel and decel throttle response
• IMMO OFF - Immobilizer off (AT YOUR REQUEST)
• MODE BASED MAPPING - High power mode (F) will be a pump gas map and medium power mode  M) will have changed ignition and fuel mapping for racing fuel. +8-10hp on demand
• INJECTOR BALANCING - More power found through injector balancing
• RAM AIR / Intake flap open at all speeds - Changes to ram air mapping to maximize power and top end racing at high speed/circuit racing so the bike has enrichment in extreme environments

PLEASE NOTE

• (2026+) YOUR BIKE MUST HAVE ONE OF THESE ECU NUMBERS FOR THE HANDHELD TUNER, IF YOU ARE MAILING IN, YOU CAN SKIP THIS VERIFICATION: (21175-2385, 21175-2160, 21175-2113, 21175-2328, 21175-2378, 21175-2384, 21175-1656, 21175-1702, 21175-1704, 21175-1732, 21175-2160, 21175-2113, 21175-2328, 21175-2374, 21175-2378, 21175-2384 as of 4/6).
• If your bike has a different ECU number EMAIL US BEFORE PURCHASE. Your ECU number can be found on the ECU itself in the tail of the bike. We found the ECU numbers listed cover almost all 2021 ZX-10R's. We will be working to add more and will update this page when we do.
• Due to the sensitive nature of the ZX-10R's AFR (air/fuel ratio) and the platforms almost endless aftermarket options, the file we deliver you may need the fueling to be adjusted to meet the bike's individual needs. In this instance we recommend a piggyback fuel controller and dyno time, or an "auto-tuner" that can aid you in correcting your fuel maps (if needed).
  
• Stage 2 should be ran on 93 octane Shell V power pump gas or better to achieve best results

**Testing performed with California ACN 91 octane pump gas. Usage of a lower octane will yield smaller power gains. Higher octane larger gains**

THE BT MOTO HANDHELD TUNER

• NO DOWNTIME - No need to send in your ECU or remove it from your bike at all. You order the handheld, it get's delivered to you, you flash your bike. You never miss a day of riding and no effort removing the ECU.
• STORE MULTIPLE MAPS - When you send in your ECU, you only get one map. You might be thinking, "why would I need more than one map?". Storing multiple maps means you're able to flash for different fuels. If you're a serious track competitor, we can work with you to get you different mapping for different tracks. If, for example, you're add an exhaust to your stock bike, we can email you a file that takes the new exhaust into account with the changes you need to optimize your bike's new modifications.
• GO BACK TO STOCK ANYTIME - Not only can you store multiple race maps, you can also flash the original, stock file back into the bike at any time and for any reason.
