Detailed description

Injection & Ignition (K4x)

Improved in V2020!

  • Optimized torque curve for race exhaust systems and fuel >= 98 ROZ
    In "S" Stock-variant for stock exhaust systems, standard fuel is possible, >=95 ROZ recommended.
  • Softer throttle response and power delivery through full partial load optimization
  • Power increase from 3 to 7PS* possible (depending on bike hardware)
  • Torque increase from 2 to 5Nm* possible (depending on bike hardware)

AFR control (only BMS-O ECU)

  • O2 sensors before CAT stays used for broadband air-fuel-ratia (AFR) control
  • Faster adjustment after speed and / or load change (see schematic diagram)
  • Performance-optimized target in the upper engine speed range
  • Optimized rideability / throttle response in the low load range
  • Reduced constant ride jerking

e-Gas, S1000RR 2019+ (Race Map + Power Map)

  • Prepared for usage of short throttle grips (min. ≥54 ° rotation angle)
  • Maximum torque and power delivery in all riding modes
  • Remove any existing specific restrictions due to noise or emission regulations
  • Constant throttle response in all modes
  • Optimized behaviour for racing use
  • Increased robustness against unnecessary safety shutdown (eGas monitoring)

e-Gas, S1000 (R/XR Power Map)

Improved in V2020!

  • Optimized throttle response in ROAD, DYNAMIC & DYNAMIC PRO mode
  • Max. torque and power available in ROAD, DYNAMIC & DYNAMIC PRO mode (100% throttle valve opening)
  • Rider mode "RAIN" remain untouched
  • Remove any existing gear-dependent restrictions

e-Gas, S1000 (Race Map + RR Power Map)

  • Ready for short twist grips ≥54° (not available for BMS-K ECU)
  • Programming of same E-GAS setup - according to twist grip and engine rpm - in all riding modes
  • same - race track optimized - throttle response in all riding modes
  • max. torque and power is also available in "RAIN" (max. 60% throttle in stock ECU)
  • Remove any existing gear-dependent restrictions

Engine speed limiter

  • Programming a soft start of limiter action by cylinder blank out
  • Reduced risk of bike nervousness while reaching limiter speed
  • Slight Increase of engine speed limit up to 500rpm, because "soft limiter" prevents from over-rev

Shift assistant (SASS), quick shifter

Improved in V2020!

  • Faster upshifts (mainly in high rpm) through reduction of ignition cuts
  • More dynamic downshifts through increased throttle punch in low and mid rpm range
  • Increase of diagnostics tolerances to prevent safety shutdown during usage of race shifter (e.g. MCT-Lohmann)

Exhaust flaps (in S-variant)

  • Acoustic flap always open while riding, stock behavior in idle speed
  • Optimized Sound and torque during lower and mid rpm range
  • Better audibility of the bike while braking through open exhaust flap
  • Intake flap (e.g. at S1000RR 2019, K67) always open

Prepared for common race conversions (only in "R" version)

  • Exhaust flaps and servos can be removed
  • O2 Sensors 
    (from 2019: Broadband sensor before CAT must remain, after CAT can be removed)
  • knock control sensors can be removed
  • secondary air system can be removed
  • radiator fan can be removed (function stays enabled as long as connected)
  • 2017+: fuel tank venting valve including activated carbon filter can be removed
  • 2019+: intake flaps stays always open and can be removed
  • 2019+: CAT heating inactive (no increase of idle speed in cold start conditions)
