Dyno tune with CO adjustment Leo Vince

[krid80]

Just ran the FZ on the dyno for the first time with the Leo Vince exhaust.

Here's the setup: 2006 Yamaha FZ6 with Leo Vince exhaust with cat eliminator, db killers out.

Previous run totally stock 89.10hp
Today's runs:

Run 1 (stock tune) - 93.20hp

Run 2 (+4 C1 and C2) - 93.82hp

Run 3 (+9 C1 and C2) - 94.77hp

Run 4 (+14 C1 and C2) - 95.11hp

Run 5 (+19 C1 and C2) - 95.60hp

Run 6 (+24 C1 and C2) - 95.79hp

Run 7 (+29 C1 and C2) - 95.68


so there it is. Leo Vince with stock tune will give you 4hp but there is extra power to be had by using your CO adjustment.

Overall, I ended up with a 7hp gain with only exhaust added. I am still running a stock airbox and filter. The bike has 4200 miles.

thats good to see,,,i really am curious what would happen to add a filter and pc3 to the combination...please let us know if you do

Thanks for the post. How did you make the adjustments???

[krid80]

You have to jump a wire under the tank to a ground and then it unlocks the CO adjustment available through the gauge cluster in diagnostic mode. There are a few posts out there about how to do it. I used a Radioshack DB9 pin on a wire to a ring terminal under a bolt on the rear master cylinder. I just left it in there and all is well.

Very cool...nice to know you can hot rod computers from the factory

What type of rolling road are the results from? Over here we have a lot of tuners using inaccurate rolling roads so have to ensure we use the Aussies Dyno Dynamics for accurate figures!

Actually, Europian model can access into CO adjustment without making short circuit but, your report helps us a lot that CO adjustment will influence from idling to 14k rpm.

Thank you,

we use a dynojet brand dynamometer.

seat of the pants i really can feel a difference. it definately wants to wheelie under full throttle and certainly feels more responsive. i suppose a 7hp gain is noticable; when you look at percentages, it is almost 10 percent up!

How do you find the noise of the exhaust as is too? I fitted mine last night, and it seems a bit loud. I'm hoping it's going to quieten down, otherwise it might need the cat putting back in! With db killers out, it sounds possessed!

I was quite suprised to find the frint lifting a bit more in both first and second today. Last night when I took the baffles out, it feeled more sluggish though (totally standard, no map adjustments).

they are loud but I like their sound. Granted, if I am near a cop I upshift as to not tick him off, but if I am in someone's blind spot, I need to appeal to one of their other four senses or they will not know I am there.
