BT Moto (20-26) Kawasaki Z H2 Stage 2 ECU Flash Upgrade Add-On

STAGE 2 IS WHAT WE CONSIDER THE MAXIMUM LIMIT FOR THE STOCK ENGINE AND CAN ONLY BE RUN ON 93 OCTANE PUMP GAS OR BETTER. DO NOT PURCHASE IF YOU INTEND TO USE 91 PUMP GAS.

WHAT'S INCLUDED IN ADDITION TO OUR STAGE 1 FEATURES

(CLICK HERE TO SEE STAGE 1 FEATURES)

• Modified Quick Shifter (Race Tools)
  
• RPM and Throttle-Based Fixes for instant on 100% throttle power for racers
• Fueling Cut option
• Increased RPM Limiter for higher peak horsepower
• More aggressive ignition for higher peak horsepower
• Cruise control map limit raised from 85 to 135mph
• "M" Mode Based for racing fuels and Ignition maps in medium power mode, on the fly
• More power found through Optimized Injector Balancing at high rpm
• “Ram Air” Map Changes

THE DETAILS OF ALL CHANGES

• 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 "maximum" 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 bikes 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 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 riders enjoyment but also 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 12,700 RPM. We have been testing 13,650 RPM with zero negative side effects. We set the RPM limiter for 13,650 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.
  
• CRUISE CONTROL LIMITER OFF - 80mph isnt enough sometimes.
  
• MODE BASED MAPPING - High power mode will be a pump gas map and medium power mode will have changed ignition and fuel mapping optimized for racing fuel.
• INJECTOR BALANCING - More power found through injector balancing at all rpms
• RAM AIR - Changes to ram air mapping to maximize power and rideability on the limit

STAGE 2 TUNING UPDATES

• Revised tuning across all throttle angles , not just wide-open throttle.

• New files available for:

  • Fuel-only changes

  • Intercooler setups

  • Intercooler + supercharger gear setups

• Improved high-RPM mapping to help the bike rev out cleaner and reduce factory pinging in the upper RPM range.

• Part-throttle areas are fully mapped, especially the 25% throttle range where the bike spends most of its real-world riding time.

• Cruise-control areas are optimized for smoother riding and maximum MPG.

• Factory cruise-control speed limit raised beyond 85 mph.

SUPPORTING MODS AND ENGINE SAFETY

• Airflow testing has shown up to +10 HP with a clean high-flow filter setup.

• The Xtreme Creations intercooler is highly recommended, reducing intake temps by roughly 20–30°F .

• Cooler intake temps are critical for back-to-back racing, long pulls, high-IAT conditions, and engine longevity.

• We avoid unsafe tuning shortcuts like excessive ignition timing, lean air/fuel ratios, and unmapped part-throttle areas.

• Our focus is safe, repeatable power with better drivability, reduced pinging, and long-term reliability.
