Brentuning Moto 2020+ BMW S1000RR Stage 2 w/ IAT Relocation Kit and Intake Flapper Kit

TYPE: ECU Tuning / Programming.

DESCRIPTION:

Stage 2

Following the release of our wildly popular Stage 1 Flash we needed to sit down and really start to look at what the 2020 truly has to offer.  Anyone with our Stage 1 Flash will tell you how much it improved acceleration, got rid of the now infamous “dead spot”, fixed the OEM idle issues, and made the motorcycle feel better and more smooth overall.  Stage 2 has months of research and development behind it as well as datalogging and dyno testing.  The new 2020 S1000RR is familiar to us but also completely changed.  To that end we were able define new ECU strategies that we can help make this already impressive bike even more impressive.   Stage 2 is a feature map making the bike more consistent, more reliable, and smoother and combined with our IAT Relocation and flap delete kit results in a much improved motorcycle!

Includes all benefits of Stage 1, with these added features:

• Octane adjustments
• Corrected cold/warm start idle
• Re-calibrated timing
• Lower max lambda, leaner high RPM Target
• Higher RPM limit without throttle cut for roll racers
• 30% faster up and downshifts
• Includes our IAT extension kit and intake flapper removal kit

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 the multiple ignition maps and factory widebands, we are able to increase performance based on knock detection. This also means if you have some bad fuel, the motorcycle will still compensate and put the bike into safety mapping just like the OEM ECU would. This ensures your bike stays consistent and reliable.

Corrected cold/warm start idle to 2015 RR levels, finer tuning beyond Stage 1. Stage 1 did a lot to correct the startup issues the 2020 S1000RR 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 lean popping, idle hunting or stalling (see comparison video below).

Re-calibrated timing for higher octanes to make use of race fuels on same tune. The 2020 S1000RR has multiple ignition maps and based on knock feedback, the bike will start to adjust to different timing maps. 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 Target for a few more horsepower. AFR (air/fuel ratio) adjustments have been made to Stage 2 to be more aggressive to get a little more power out of the bike while remaining safe.

Higher RPM limit without throttle cut for roll racers (optional) With Stage 2 we are able to raise the RPM limiter to 15,000 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 now.

30% faster up and downshifts over Stage 1 and now allows the use of fast shift sensor products on the market if desired.

BT MOTO IAT RELOCATION AND FLAPPER KIT

PLEASE NOTE: UPON REQUEST WE CAN COMMAND THE INTAKE FLAPPERS OPEN THROUGH FLASHING ONLY. THIS IS FOR CUSTOMERS THAT WOULD PREFER NOT TO REMOVE THE INTAKE FLAPPERS FROM THEIR MOTORCYCLES.

WHAT DOES THIS KIT DO?

• Relocates the Intake Air Temp (IAT) sensor and removes the airbox “flappers”.
• Moves the IAT sensor from the factory location near the cylinder head to the front of the bike to get a true ambient reading.
• Removes factory airbox flappers to allow fresh air to enter the airbox at any speed, RPM or gear.
• A true ambient reading means more power but also means consistent power.
• Noticeable improvements in stop-and-go traffic, starting a race from a stop and exiting the pit.
• Even distribution of air to all cylinders without any cylinder bias.
• More air to the engine with plastic flappers removed.
• No downside and dyno proven gains across the powerband (see dyno chart below).
