Frequently Asked Questions
What's the difference between a "real world" tune and a dyno tune?
As many may know, our focus is on maximizing the performance of a motorcycle through efficiency. A Dyno ultimately is designed to do the very best to duplicate real world engine load in a more controlled environment. However, its very best isn’t very good. The problem is the Dyno just can not duplicate real world ram air and engine load parameters to properly dial in fueling. So you may get a great tune on a Dyno that has perfect Air/Fuel ratio and the bike is putting out maximum power. Then once you take it out into the real world, everything has changed because the environment has changed and that perfect tune on the Dyno is no longer perfect. This is where Real World Tuning comes into play.
We tune the motorcycle in its actual operating environment. This results in a more efficient, powerful running engine as well as a much superior partial throttle experience as it is almost impossible to dial in throttle transitions on the Dyno. The down side to a Real World Tune is that we can’t produce a visable HP number on a graph. But this is where your decision making skills come into play.
Do you prefer to go faster? Or have a Dyno number to brag about? You decide!
What is ecu flashing? is it safe?
The short answer? Yes it is absolutely safe if you choose us! We have a philosophy here at EJR Performance and that is, a safe tune is the only tune. There has been this trendy way of thinking that you can push a motor harder and harder and it will keep making more and more power. Unfortunately that is not the case. An engine will not make power past MBT (maximum brake torque). So there is no reason to push it harder than it needs to be pushed. All you are doing is shortening its life. A safe, reliable, tune or flash will results in maximum performance AND maximum life.
which sprockets should i use?
This is the most commonly asked question and unfortunately, there is no perfect sprocket combo. Its the cherry on the cake. The best answer that can be given is whatever combo gets you to go A to B the quickest/fastest for your desired race of choice. Rider weight, motorcycle weight, power, aero, tire size, etc all factor into that final desired sprocket combo.
