(25-27) BMW S1000R Stage 2 ECU Flash Upgrade

STAGE 2 IS A MAP UPGRADE ABOVE AND BEYOND OUR STAGE 1 MAP. STAGE 2 IS DESIGNED AROUND FULLY MODIFIED BIKES, THAT MEANS YOU SHOULD HAVE AN EXHAUST, FILTER, IAT RELOCATION, FLAPPER AND OUR VELOCITY STACKS. THE MOST COST EFFECTIVE WAY TO GET ALL THESE PARTS IS TO ORDER OUR INDUCTION KIT HERE

Following the release of our popular Stage 1 Flash we needed to sit down and really start to look at what the 2025 S1000R truly has to offer. Anyone with our Stage 1 Flash will tell you how much it improved acceleration, fixed the OEM idle issues, and made the motorcycle smoother while also added power and response.  

Stage 2 has months of research and development behind it as well as additional datalogging and dyno testing. The revised 2025 S1000R is familiar to us but also completely changed. To that end we were able define new ECU strategies that help make this already impressive bike even more robust. Stage 2 is a feature upgrade map making the bike more consistent, smoother, while also keeping the bike factory reliable. Combined with our IAT Relocation and intake flapper delete kits result in a noticeably improved riding experience!

BENEFITS OVER STAGE 1

Stage 2 includes all benefits of Stage 1, along with these additional features:

(CLICK HERE TO SEE STAGE 1 DETAILS)

• Octane adjustments based on optimized ignition and knock feedback changes
• Corrected cold/warm start idle
• Recalibrated ignition timing tables
• Lower max lambda, leaner high RPM Target to optimize power
• Higher RPM limit without throttle cut for roll racers
• Faster up and downshifts
• Can utilize our optional IAT relocation kit and intake flapper removal kit
• Designed to work with our velocity stack kit linked below
  
  

HOW DO WE ACCOMPLISH THIS WITH STAGE 2?

• Octane adjustments for auto adaptation on pump gas for US and international fuels 91-94 octane 95-100 RON. Utilizing multiple ignition maps and factory widebands, we are able to increase performance based on knock detection. This also means even if you have some bad fuel, the motorcycle will still compensate and put the bike into safety mapping just like the OEM ECU tuning would. This ensures your bike stays consistent and reliable while making the most power possible.
• Corrected cold/warm start idle for finer tuning beyond Stage 1. Stage 1 did a lot to correct the startup issues the S1000R was having. Stage 2 goes a step further. There is no longer a high idle that transitions into a lower idle. The idle remains static without any high idle, lean popping, idle hunting or stalling.
• Recalibrated timing for higher octanes to make use of race fuels on same tune. The 2025 S1000R has multiple ignition maps and they're based on knock feedback. The bike will start to adjust to different timing maps given the feedback it gets from its sensors. This means if you have a high octane fuel in the bike or race fuel and knock isn’t present, the bike will transition to a more aggressive timing map automatically. A more aggressive timing map will safely allow the bike to make more power. No more flashing every time you want to use race gas, although we can still provide specific race fuel mapping designed to be used on ONLY race gas. This feature is most beneficial when you are on the track or street and don’t have your handheld available to swap maps.
• Lower max lambda, leaner high RPM Targets for more horsepower. AFR (air/fuel ratio) adjustments have been made to Stage 2 to be more aggressive remaining safe.
• Higher RPM limit without throttle cut for roll racers (optional). With Stage 2 we are able to raise the RPM limiter to 12,500 RPM while also making sure the raised RPM event is not stored in the ECU. We have also adjusted the spark and fuel cuts so when the rev limit is hit, the bike doesn’t feel like you slammed on the brakes, it’s more gentle.
• Faster up and downshifts over Stage 1 and now allows the use of fast shift sensor products on the market if desired.
