STAGE 2 ECU CALIBRATION:
Our Stage 2 is the next step beyond Stage 1, designed for riders who want maximum performance, sharper response, and more aggressive behavior for track use and high-performance riding.
This calibration builds on the solid OEM-level foundation of Stage 1 and introduces advanced strategies focused on airflow, fueling, ignition, ShiftCam control, and race-oriented logic.
Stage 2 is recommended for riders with aftermarket exhaust systems or those looking for the highest possible performance without compromising engine safety.
WHAT CHANGES FROM STAGE 1
• More aggressive throttle and torque delivery
• Advanced ShiftCam high-lift strategy at high RPM
• Race-oriented quickshifter logic
• Expanded fueling and ignition control
• Higher RPM operating logic
• Flames in neutral functionality available upon customer request
• Track and aggressive street behavior
PERFORMANCE GAINS
- +15-20 HP to the rear wheel
- +12-15 ft-lbs torque across the powerband
- Crisp throttle response with zero lag
- Smoother power delivery in all riding modes
- Optimized fuel mapping for aftermarket exhausts
STAGE 1 VS STAGE 2 - WHICH IS RIGHT FOR YOU?
| Feature | Stage 1 | Stage 2 |
|---|---|---|
|
HP Gains Across the entire RPM range |
+10-15 WHP | +15-20 WHP |
| Torque Gains | +6-8 ft-lbs | +12-15 ft-lbs |
| Exhaust Required | Stock OK | Aftermarket recommended |
| Best For | Street riding | Track & aggressive street |
| Price | $939 | $1238 |
Our Recommendation: If you have an aftermarket exhaust or plan to get one, Stage 2 is the clear choice for maximum performance.
REQUIREMENTS:
• Stage 1 calibration required
• Carita handheld tuner required
• Aftermarket exhaust recommended for best results
Technical Features & Adjustments
1. Throttle & Torque Limiters Removed
Factory ECU limits throttle opening by gear and RPM.
Please refer to the table below, which represents one of the throttle valve management maps. As shown, second and third gears are significantly more restricted than the other gears, and above 13,750 RPM the throttle is electronically reduced to 87% opening.
With our flash, all of these restrictions are eliminated, allowing 100% throttle opening in every gear and across the entire RPM range, with no electronic limitations.
2. Fueling Optimization
• Revised fuel maps for a target AFR of 13.1 under load, ensuring ideal combustion and maximum power output.
• Closed-loop corrections adjusted for smoother transitions between part-throttle and wide-open throttle. Perfect Fuel Adjustment Full Time
• Automatic octane adjustments
• Self Autotune for Pump Gas 89, 90, 91, 93, 95, 100 Or Vp Mr12
• You can mix or use different octane and our flash in conjunction with the ecu will make the necessary adjustments
• Control and Adjustment Of Fuel Per Cylinder. (Only Carita)
• Option To Upgrade For E85 Fuel
3. Ignition Timing Adjustments
• Optimized ignition advance across the rev range for increased torque and horsepower while maintaining safe knock margins.
• Ignition Timing Maps Calibrated For Faster Acceleration
• Adjustments To Knock Control
4. Intake ShiftCam Configuration:
In the image below, it can be observed that above 14,300 RPM, the factory calibration commands the ShiftCam system to revert back to the low-lift cam profile.
With our flash, ShiftCam is programmed to remain in the high-lift cam profile, sustaining maximum airflow and power delivery at high RPM.
This advanced calibration capability is exclusive to Carita, and is not available through standard aftermarket tuning platforms.
5. Quickshifter & Auto-Blipper Refinement
• Improved downshift blip timing
• 45% Faster Up and Downshifts
• Race-style ignition cut logic inspired by 2025-2026 BMW M calibration
6. RPM
• RPM limiter raised for extended top-end power (within safe engine operating limits)
7. Exhaust Valve, Intake Flap & Emissions Controls
• Exhaust valve behavior reprogrammed for consistent flow and reduced heat buildup.
• Removal of unnecessary emissions-based restrictions that hinder performance.
• Exhaust and Intake Flap Open 100% In All Gears
It can be seen in the image below that with the OEM software, the Ram Air flap remains closed up to 7,500 RPM, preventing proper airflow from entering the intake system.
With our calibration, the Ram Air flap remains fully open at all times, or it can be completely removed without triggering any check engine light.
• Exup, Evap and Pair valves DTC off. If you remove these valves it will not turn on any DTC code but if you leave them on, they will continue to function with the modifications included with stage 2
8. Fan & Temperature Management
• Revised cooling fan activation temperatures for better heat management in street and track conditions.
• Fan On From 215F To 186F.
9. Speed Limiters
• 170MPH limiter (due to torque) removed
• Speed Limiter Off
Measured Results (Typical Gains on Pump Gas)
• +15–20 whp increase in the midrange (6,000–10,000 rpm).
• +8–10 whp increase at peak power.
• Noticeably stronger torque delivery in lower gears.
• Sharper throttle response and improved acceleration times.
Velocity Stacks:
Aftermarket Velocity Stacks Not Required
Based on extensive testing and data analysis: The stock M-series intake system is highly efficient; current aftermarket velocity stacks do not provide a increase in horsepower or torque.
Performance Benchmarking: To date, no aftermarket intake accessory has outperformed the M factory configuration.
Recommendation: We recommend retaining the original M Airbox & stacks setup for optimal pressure waves and throttle response across the entire RPM range.
DRAGY TEST:
Bike with ONLY full Akrapovic exhaust, sprint filter, our IAT relocation and our Flap Delete Kit. NO LOWERED
DYNO TESTING:
Our Flash Was Created On a 2025 M1000RR At Our Dyno In Miami After Several Days Of Testing.
