However by wiring the resistor into the harness you could get a US ECU to work on an EU harness.įor what it is worth the only difference between the two ECUs software some of the Secondary throttle and Exhaust servo maps are slightly different. If you you use the US ECU you will need the lock with the resistor in it. So if you use an EU ECU you will need an RFID lock/harness and the matching key. The ECU measures this voltage and if the ratio is not correct the bike will not start. The US bikes have a resistor in the ignition lock that makes the voltage on one of the power wires coming out of the lock to the ECU a fraction of the battery voltage. The number in the key needs to match the number in the ECU or the bike won't start. The keys have little RF identification (RFID) chips in them that broadcast their unique number when they detect the query from the ECU. The "immobilizer" on the EU version has a little antenna around the lock that broadcasts an Radio Frequency (RF) signal. The Part numbers are.īoth the US and EU have anti-theft that will immobilize the bike but they are different. The long systems do make more power than the shorty systems that seem to be a fad now-a-days.Found this posted by RidgeRacer on this site: Tweaking your ECU means removing things like low RPM power. No clearance issues, everything fits perfectly, and tucks up completely out of the way. ECU tuning is the art and science of cracking the code that the factory installs in your motorcycles brain and giving it an upgrade. The rigorous standard we use to determine what products we should sell reflects Brock’s competitive spirit on the racetrack. The system is very affordable, and the quality is impeccable. We design our products to reignite the motorcycle enthusiast’s soul, and our team goes to great lengths to ensure every product’s quality. The difference in power with the full exhaust is more than substantial, not to mention the weight savings. I was worried, but now my fears are at rest. And with the optional baffle, no worry about it being too loud. I see why they are being used by the pro's. It doesn't matter what gear I'm in, this bike is doing over a hundred, and with the ECU unrestricted, the power up to 14000 rpm is so intense, that I just have to concentrate on being smooth. This bike is so fast for normal riding, that whatever minor loss in power created by the baffle is just not noticeable. Big plus for street riding, or for areas where excess sound can be a invitation for a ticket. I put in the optional baffle, and it sounds like any other normal full exhaust. Tuned it with the stock open exhaust, extremely loud, which may be a concern for many for the street, or for a track that has noise restriction. Really worked on midrange torque, and smooth power delivery throughout the power band. He spend 2 days fine tuning it, and we got it right on. ANYWAYS, Im trying to remove the ECU for a flash tune and am just staring at whats under my seat. The bike has been transformed into a beast. Ive done a search on here and on google and couldnt find anything, which is actually a bad sign for me, as that usually means Im missing something incredibly easy. Lolįinally got the bike back from my dyno guy and got a chance to ride it. Don't be the guy who couldn't keep riding because the exhaust was too loud, cus then it won't matter how much power it makes if they won't let you ride. Some tracks have the noise limit, some don't. My old track I used to go to had a dB limit, and honestly I like my bike to be not loud, helps me focus on track if someone isn't able to shout in my ears through my ear plugs. Not sure what the go-to slip on cans for your exact bike are, but just stay away from 'shorty' pipes or other 'mufflers' that are hardly a piece of pipe, and it should be fine for street driving and track. Perfect volume on the TRS as well for me, loud when you get on it, and very quiet and peaceful when you're just cruising. Runs better in every way, and is now better for street and track. Had ECU flashed and dyno tuned for fueling, remove the fuel cut on decel, and she's a whole new bike again. Found a good shape stock header, and bought a Yoshi TRS can. My bike needed a whole exhaust, and I almost did the full system but didn't on this premise.
