About the Product
The BMW R18 is the new motorcycle for those wanting a unique heritage cruiser, so we received two test bikes to dial in to put our twist on. Both in completely different weather climates to test in cold, hot and moderate weather. We made sure both bikes behaved the same and yielded the same results, without issues.
STAGE 1 BENEFITS
Perfect fueling, all the time! The BMW R18 comes equipped with wideband oxygen sensors stock which fully target fuel at every throttle position. Once setup, the bike is running an “auto” tuner all the time! Never needing custom adjustments for aftermarket parts, etc. The bike will adjust itself for the new parts! With the options below we have a full on unleashed and aural riding experience to enjoy this motorcycle to it’s best possible potential.Here's a list of everything we did with Stage 1:
- Full-Time Closed Loop (FTCL) Fueling Adjustments
- Removed RPM "Soft" Limiter
- Rough Idle Fix - Cold and Warm
- Increased Torque Limits
- Increased Throttle Limiter To 100%
- Sharper Throttle Response
- More Aggressive "Rock" Mode Rumble
- Increased Ignition Timing
- Fixed Bucking and Rev Hang
- Removed Top Speed Limiter
HOW WE ACCOMPLISH THIS WITH STAGE 1
RESTRICTIONS REMOVED. The OEM throttle model has "soft" and "hard" limits. The soft limits are where the R18 will start to close the throttle and limit torque by itself near the RPM limiter. We removed the soft limiter that comes in 600RPM before the factory RPM limiter.
MODIFIED FUELING FOR FULL-TIME CLOSED LOOP AND WILL TARGET FOR BEST FUELING AND PERFORMANCE. Full-time closed loop tuning means your R18 can be programmed to always target a perfect AFR (air/fuel ratio). This new technology was just introduced by BMW and we utilize it to work at all times for you with Stage 1. Want to change parts on your bike and worried it may change your fueling? Worry no more with Stage 1.
MODIFIED IGNITION FOR ENHANCED PERFORMANCE. Stage 1 optimizes the ignition tables for performance and reliability. The R18 has multiple ignition tables. Depending on fuel quality, the bike will either choose more aggressive or less aggressive ignition map.
IDLE AND STARTUP FIXES. Complaints of idle and startup issues are common. Stage 1 fixes these issues and ensures your bike starts up and idles right the first time, every time.
INCREASED TORQUE LIMITS. Torque limits removed to give you more torque in the midrange and low end (see dyno graphs below).
THROTTLE INCREASED TO 100%. Factory throttle limits are common these days. Our Stage 1 flash removes all throttle limiters and gives you the power your bike should have had right from the factory. The factory R18 throttle limiters are at 3500RPM.
SHARPER THROTTLE RESPONSE. Throttle response sharpened to give you a more lively and responsive feel on the road.
INCREASED "ROCK" MODE RUMBLE. Ready to Rock? "Rock" mode idle gives you slightly more rumble and shake, while "Roll" mode still retains its functions with no shake.
INCREASED IGNITION TIMING. Ignition timing carefully increased to yield optimized power while still giving you OEM reliability and ridability.
FIXED BUCKING AND REV HANG. Low RPM bucking and throttle lift "rev hang" have been reduced with Stage 1.
REMOVED TOP SPEED LIMITER. Top speed limiter of 110MPH had been removed with Stage 1
