Not anywhere near the screaming bleeding edge performance of a gahtdayum r1, but I love my nine hundo.
#ECU FLASH R1 FULL#
And I’m giving this advice because what did I do when I got out of training and for the first time in my life had some toy money? Bought a new bike and slapped a full exhaust on it without having a clue what I was doing haha. If I was fortunate enough to have an r1, I would never alter the fuel mixture without having a near optimal solution like a dyno tune.Īnyway, your bike, you worked hard for the money to buy it, enjoy it YOUR way, since you asked this is my advice: enjoy your amazing top tier bike stock until you are more familiar with how it works and more options for fuel management are available. I’d suggest you hold off on the exhaust until a better solution is available, and at MINIMUM until you can at a glance tell the difference between a full system and a partial exhaust, and know all the implications of fuel/air mixture alterations. I lost a bit of power midrange (which unlike a real deal race replica sportbike is where a lot of the power is on a z900) but also had a small but noticeable input lag on the throttle. I had a power commander on my z900, but sold it within a week and got an ecu flash. An ecu flash or dyno tune (which may not as you say be available yet) allows changes to ignition timing, engine braking and lots of other parameters. All they do is change the duration of the fuel squirts. Power commanders will work to a degree, but they are passable yet suboptimal solutions. This is not intended to be offensive or an attack, but the nature of your question suggests you don’t have that education yet. My recommendation (the advice of an Internet stranger, so take it for the very little it’s worth) is to not make big changes to the core functioning of your nearly $20,000 rocket ship until you are very educated on all aspects of the changes you are making. You will almost certainly lose some performance by altering the mix without adjusting fueling. In addition, as mentioned this is a finely tuned system. Significant alterations to the airflow and the thus the air/fuel mixture may not make your bike blow up tomorrow, but you will almost certainly make it run lean and thus run hotter than spec, and will cause significant extra valve wear.
You basically have to go to motogp bikes to get more performance than a new r1. Just off the top, you have a bad mofo of a super ultra finely tuned high performance machine.
The r1 has a “breadbox” and a cat under the bike, the breadbox helps with sound mitigation for regulations and also is a significant impediment to airflow. This is a significant change to your airflow system even if it’s the only change.
