BMW S1000 XR Brentune Stage 1-3 flash

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.

 

Back in the saddle

After a massive retina detachment in July of 2021, the rest of the year was pretty somber as far as riding goes. No riding for 6-7 months. Eye is back to almost normal, with some different correction that worked extremely good. Having a very talented eye surgeon helped as well. Can’t thank the surgeons and nurses at Carolina Eye Associates enough for what they did. Outstanding.

She didn’t complain at all when I took her out to stretch her legs. Awesome bike.

Microphone test with GoPro Hero 6

Trying out a new mike for a GoPro Hero 6 (I know, I need a Hero 9). Have tried a few different mikes, and all of them distort (clips) the input into the camera at higher speeds. This mike will probably be a keeper (Giant Squid lapel mike). Sounds pretty good, even at higher speeds, without any cracking or distortion. It’s a keeper.

Left the house in SC at 6am. Interstate all the way for 460 miles. Raining off an on. Arrived around 2PM, and set up camp at Shawnee State Park campground.

Shawnee State Park, OH

Went for a group ride Friday. Very nice roads in Southern OH. The rain just would not quit.

Group Ride again Saturday. Nice weather. Shot some video with my GoPro Hero 6. We had around 15 riders in the group, using the “drop and sweep” system, which works very good.

 

Great weekend.Met a lot of old friends, along with a few new ones as well.

Returned home Sunday 6/13. 

New shoes on the GSA

New shoes on the GSA

Mounted the second set of Pirelli Scorpion Trail II on the R1200 GSA. Great touring tire. Had a plug in the old rear, and was also starting to wear down quite a bit.

Pirelli took it a step further with the II designation, redesigning the tires to better suit road-focused adventure touring bikes. As a touring / sport-touring tire, the Trail II offers ample confidence-inspiring grip and predictability. This is not surprising since the Trail IIs are derived from the Angel GT. Compared to the old Scorpion Trail the new tire features a rounder profile that creates a contact patch 6 percent shorter and 10 percent wider. The new tread pattern does away with the intersecting grooves and the big block tread pattern of the old Trails in favor of a more street-bred, continuous block pattern that delivers improved lateral stability with less road noise and vibration. Pirelli claims the new profile and tread reduces heat and increases longevity by 50 percent without the need for a harder compound.

Deep, steeply angled grooves promise to discharge water more effectively, and new compounds will improve both wet and dry weather performance. The front tire has a single, 100 percent silica compound while the dual-compound rear tire features a 100 percent silica shoulder and 70 percent silica center that balances corner grip with longevity. Pirelli’s super-secret compound cocktail is concocted using a unique process of continuously mixing polymers and resins with silica that chemically bonds to carbon black for more consistent wear and performance
