Overview




The 2023 ZX-4R / RR is one of the most requested products we've had this year. Customers are very excited to see this bike unlocked and we were the first to finish this project for the community. Being the first to unlock the 2021 ZX10is never enough for us. We want to make sure that people are not only satisfied with our flashes, we want them to be amazed with the results. After taking some time to develop our mapping, we think we have something everyone will be happy with.




 WHAT'S INCLUDED WITH STAGE 1 ZX-4R / RR FLASH


  • Fueling Adjusted (per gear)
  • Ignition Adjusted (per gear)
  • Throttle De-restricted (per gear) +15hp
  • Lower Fan-On Temp
  • Increased RPM Limiter
  • Removed Top Speed Limiter




THE DETAILS


  • FUELING -  With custom tuning we can target better AFR (air/fuel ratio) plots to enhance not only racing performance, but also cruising and partial throttle inputs. On the ZX4 there is a lot of extra unnecessary fuel to limit the bikes performance. On the same front, better fuel economy can be retained.
  • IGNITION - Optimized to make the most power while still being safe and reliable.
  • THROTTLE DE-RESTRICTION - Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has a “dead spot” on the top end that kills the bikes power curve when it should be making the most. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline.
  • LOWER FAN-ON TEMP - Let’s face it, this bike rides a little on the hot side. To help not only the riders enjoyment but also keep the engine slightly cooler, we've lowered the fan-on temps.
  • INCREASED RPM LIMITER (at customer request) - We can raise the factory limiter by 500 rpms safely at your request.
  • INCREASED TOP SPEED LIMITER - Removed so you can let the bike run free in any track environment.




PLEASE NOTE


  • YOUR BIKE MUST HAVE ONE OF THESE ECU NUMBERS: (21175-1861, 21175-1855, 21175-1876, 21175-1867, 21175-1873, 21175-1874, 21175-1866, 21175-1862, 21175-1863, 21175-1865, 21175-1875).
  • If your bike has a different ECU number EMAIL US BEFORE PURCHASE. Your ECU number can be found on the ECU itself in the tail of the bike.  We will be working to add more and will update this page when we do.

+20whp gains on these models by flashing the ecu, which is insane for this small engine!







 

THE BT MOTO HANDHELD TUNER


 

WHAT IS A "FLASH AT HOME" HANDHELD PERFORMANCE TUNER AND WHAT ARE THE BENEFITS OF HAVING ONE?

 

Custom tuning at your finger tips on your schedule. Read and write your own motorcycles ecu in the comfort of your home. No longer need to bring your bike to a shop, buying a $1000 hardware kit + time + dyno then paying for time of a technician one time deal. You now have a virtual custom personal tuner at your finger tips. This is a for life purchase with full flexibility to transfer to other motorcycles in the future. Thoroughly tested by our own engineers, not just for its function but also durability.

 

CAN I JUST SEND IN MY ECU FOR FLASHING AND SPEND LESS? LET'S SEE THE BREAKDOWN.

 

  • NO DOWNTIME - No need to send in your ECU or remove it from your bike at all. You order the handheld, it get's delivered to you nearly instantly, and you flash your bike on your time easily. You never miss a day of riding and no effort removing the ECU. Any issues, you can revert back to the full stock state.
  • READ AND CLEAR CHECK ENGINE LIGHTS - Full diagnostic of the ecu including the device.
  • STORE MULTIPLE MAPS - When you send in your ECU, you only get one map. You might be thinking, "why would I need more than one map?". Storing multiple maps means you're able to flash for different configurations. If you're a serious track competitor, we can work with you to get you different mapping for different tracks. If, for example, you're add modifications to your stock bike, we can email you a file that takes the new exhaust into account with the changes you need to optimize your bike's new modifications with no mailing needed.
  • GO BACK TO STOCK ANYTIME - Not only can you store multiple files, you can also flash the original, stock file back into the bike at any time and for any reason for service, sales, and more.
  • ABILITY TO TUNE FUTURE BIKES - Customers swap bikes all the time! With our handheld tuner, you are able to put the first bike back to stock, then reset the device and use the same device on your next bike, with a simple and low cost transfer fee.
  • ANY ISSUES? We can resolve nearly anything remotely really quick with our engineering staff.
