WHAT THE GL1800 STAGE 1 TUNE INCLUDES

• Tune your bike from stock to BT Moto tuned yourself at home with our proprietary handheld tuner (exclusive). See the handheld tab for more details on how it works
  
• Remove the dullness of the Factory Goldwing calibration and stop being left behind by your friend's Harley Davidson
  
• Add 10+whp with modifications to ignition advance, drive-by-wire adjustments, and fueling tweaks without sacrificing engine life or having to run high octane. See the dyno graph page of our test bike.
  
• 105mph top speed limiter removal (exclusive) 130+mph capable
• Corrected fueling in “IAP" and "TPS" modes for power , throttle response, and fuel economy for a better driving experience. Removes most of the clunky DCT and Manual transmission feel
• Raised RPM limiter to +400 RPM to keep the bike on "power" better on full throttle and make a massive powerband
• Revised throttle limitations to so 100% throttle gives full 100% torque in every gear and every mode for a lively engine experience. This works in a case of emergency, needing to get out of the way of a vehicle and not being stuck in 30% throttle at full 100% twist.
• Smooth throttle modes of Tour/Sport mode to be "parking lot worthy" and remove jumpiness, but give more response and torque in driving situations. ECO/RAIN mode is left intact and stock for economy and rain riding
• On-off throttle transitions are sorted for better performance around town and traffic with electronic throttle adjustments
• Ignition timing adjustments for increased power and torque for 87-91+ fuels
  
• 20-100MPH times reduced from 10.6 seconds to 9.2 seconds, verified on GPS ( SEE REVIEW VIDEO )

PLEASE NOTE : FOR TOP SPEED TESTING, PLEASE USE FULL MANUAL MODE ON YOUR GOLDWING.
