Went ahead and pushed up stage 1-3 Brentune flash for my S1000 XR. This something I had been wanting to do for a while. Wow, big difference in every way. More torque, horsepower, smoother quick shift, and a lot more. You load down your original ECU flash down to the handheld, send it to Brentune Moto, and they send back a modified file that is pushed to the bike, again, using the handheld. Good stuff.
Stage 1:
- Full exhaust flap control for valved exhausts
- Full recalculation of the ASC torque control for straight line and cornering performance
- Per-cylinder fuel tuning designed around aftermarket exhaust systems
- Remapped throttle angles for increased power through the entire RPM range
- Better power on all fuels leading to higher trap/lap times in testing
- Smoother idle speeds and fueling for full exhaust
- Fully recalibrated UP and DOWN shifts for faster quick shifter timing (30% faster over Stage 2)
- Better cooling and engine prevention in staging lanes idling for drag strip or circuit
- Early fan-on for better cooling
- More aggressive and stronger launch control with no launch limit
- Each cylinder tuned individually for maximum power and reliability
- Recalibrated knock control to rule out “false knock” caused by engine vibration
- Recalibrated torque control for all traction control modes (sport, race, slick)
- Adjustable tire size and TC/ABS per customer request
- Full AlphaN fueling conversion
- Secondary air control (block off plate not needed)
- Transmission gear box limiters raised
- Factory exhaust control over exhaust valves for more power and better sound
- Recalibrated intake air temp and coolant temp compensation tables for max performance in all weather conditions
- Raised load torque limits for additional power
- Air mass, idle, part/full throttle and Lambda correction maps for all exhausts
- Ignition mapping optimized for more power
- Removed 80% WOT (wide open throttle) limiter
- Adjusted torque model to align with new power of bike and limiter removal
- Shorter up and downshift dead times for maximum driveability and acceleration
- Ignition/fuel calculation for maximum performance and response for almost all fuels and race gas
That’s a lot of changes and improvements. and you can certainly feel it when riding. Should have done this long time ago.
