rweakley Posted December 16, 2017 Author Share Posted December 16, 2017 Will do. I don't know, it may be all in my head, but it does feel a bit sluggish now on the butt duno since the install. Looking forward to getting this FTECU in. I'll remove the snorkel as well. So do I need to have both in or both out? I have only done both out or one in. I liked 1 or none, but I'd have to take the pipe off to do the second baffle to test that. We'll see...I'm hoping to be able to work on the bike this weekend.

stickshift Posted December 16, 2017 Share Posted December 16, 2017 Use the Yoshi map if you use just one baffle (or none), use the Akra map if you fit both baffles. Link to comment Share on other sites More sharing options...

rweakley Posted December 19, 2017 Author Share Posted December 19, 2017 (edited) @Beemer Um cuz it sounds way awesomer. My deciding factor is how it treats me on a 45 minute commute. I've done a few trips with dB killer in, and you can still hear it just fine (and I ride with earplugs). But the deep threaty rumble with it out is insane! Just need to see if its gonna drive me nuts on a long drive. That said, I think I wanna take off the muffler and install the pre muffler dB killer and see how it sounds with that one in and the tip one out. I think it's nice having two to experiment with to get the best sound. Edited December 19, 2017 by rweakley Link to comment Share on other sites More sharing options...

I agree an R77 Yosh pipe sounds good being all deep and throaty and maybe he should use both db's if the thought of it bothering neighbors bothers him, that's all I was saying. I hope you're happy with your pipe. Beemer Link to comment Share on other sites More sharing options...

It didn’t really do all that much for sound deadening. Which is fine because it sounds great without the tip db killer in, but I can throw it in if I’m feeling passive aggressive. I have it in right now and remapped for the Akrapovic. I’m having a hard time noticing if it is doing anything, but it has started getting way more popping on decel ever since the first flash (R77 with no db killer). Still doing with both killers in and Akra fuel map. Plus the injector cut on decel disable is hard to assess as well. Still seems to do a whole lot of engine braking. This is my first bike, so I’m relatively new to all this. Link to comment Share on other sites More sharing options...

I think you should talk to the people that gave you the fuel map. Sorry, I can't help. Beemer Link to comment Share on other sites More sharing options...

Someone made a comment alluding to the Yosh having 2...So I was asking about the Yosh, but talking about my own Mivv. I got the maps off the power commander website. 1 Link to comment Share on other sites More sharing options...

US oem spec bikes run like shyt compared to EU oem bikes... gotta love the cancer known as EPA Many many of these EU brand exhaust, MIVV, Black Widow, Leo Vince to name a few are built off the EU spec fueling, yes they say you may not need tuning but you will see more performance with a tune ( this a statement to convince you to buy it but also covering thy ass by saying you will see improved performance with a tune if potentially it ends up on a US bike) ... The Truth is just the opposite the new European Emissions standards are like CA CARB Standards.. the new Sport bikes like Yamaha R-6 and R-1 are down a few HP from older models with less strict emissions standards.. Stock they all run too lean .. Also this fancy talk about a tune All you have to do is increase the fuel say 5% richer and they will run way stronger.. As far as engine braking goes.. The fuel is shut off during deceleration thus you have strong engine braking and no backfires.. FZ-07 does not have a slipper clutch and hard deceleration could upset the bike on a race track entering a corner.. most guys like it to be able to free wheel better.. In a Snowmobile I live the engine braking to set up a slide in the corner on my Yamaha Apex sled uses an R-1 engine the new 3 Cylinder Yamaha has an air valve that opens and lets raw air into the intake to help it to free wheel like a two stroke Link to comment Share on other sites More sharing options...
