WHAT CAN BE ACCOMPLISHED WITH STAGE 1?

MORE RESTRICTIONS REMOVED. The OEM throttle model has “soft” and “hard” limits.  The soft limits are where the 2020 S1000RR will start to close the throttle and limit torque by itself at high speed or high RPM.  We removed the top speed governor and made sure the throttle or torque isn’t limited.

MODIFIED FUELING FOR FULL TIME CLOSED LOOP AND WILL TARGET FOR PERFORMANCE (not just rideability in the //M+ flash).  The //M+ flash focuses on smooth and consistent rideability only.  It does not take peak performance into consideration.  That may sound silly given how much of an improvement the //M+ flash gives the 2020 S1000RR but on Stage 1 we decided to focus purely on performance while still taking rideability into account.  MANY hours, days, months have gone into developing the Stage 1 flash to make sure the bike is not only fast, but also reliable, smooth and consistent.  For safety we adjust the OEM wideband sensors to read +/- 35% at all times.

MODIFIED IGNITION FOR PERFORMANCE ON VARIOUS OCTANES.  The //M+ flash did not touch any of the stock ignition tables.  Stage 1 optimizes the ignition tables for performance and reliability.  The S1000RR has multiple timing tables.  Depending on fuel quality, the bike will choose more aggressive timing tables or less aggressive (if knock is present).

MR12 HORSEPOWER AND OTHER 100 OCTANE FUELING MAPS INCLUDED. One flash does it all.  Because of the adaptive ECU and OEM wideband sensors, the S1000RR is able to switch between fuels without flashing to a new map.  This means if you want to run regular 93 pump gas then switch to MR12, you do not have to change maps.  The adaptive ECU and our Stage 1 flash will account for the new fuel and change automatically to optimize performance.  The only thing the user has to do is pump the gas in the bike and ride.

MODIFIED QUICK SHIFTER TIMES FOR UP/DOWN SHIFTING “KILL” TIMES. Faster and smoother shifting for the OEM quick shifter. We made what was already good, even better.

SPORT MODE LIMITERS ADJUSTED. Sport mode has been adjusted to offer full power with changed traction control settings for smoother riding.

SERVICE BULLETIN UPDATED SAFETY MAPS ADDED. Early S1000RR’s had incorrect ignition timing from the factory.  This was only at high RPM but it could result in knock (pre ignition of fuel in the combustion chamber).  As a result BMW issued a service bulletin and software update to rectify this issue.  We made sure to include this in our mapping while still maintaining a high level of performance and reliability.

WHAT CAN BE ACCOMPLISHED WITH 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!

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.
