When I decide to go all in and start building my own exhaust for the FZ6R I got myself the PCV and the AutoTune. It wasn't too hard to convince myself that spending the extra $$$ to get the AT and be able to fine tune my bike for my custom exhaust would be a better option than running it on the dyno, and it was about the same cost. I end up with a very solid map. Considering that most of the FZ6R Forum member use my map... I think I got the job done right.

Since then I got into more serious modding, since I can afford a bigger bike right now (Wife full time student for the next 2 years) I did the FZ6 cams swap (first and only one!) and re-design the airbox with different stack.

I did that early this year and I never got the tune perfect as I did for the first map. In a desperate move I went on the dyno and get the bike tune. But like probably any dyno tech. He got the bike tune at 100% throttle and pretty much dump more fuel until the bike start loosing power then go back one step. So I end up with a very good result at top end WOT but pretty much suck everywhere else. At + 30-40% fuel in the mid range it wasn't going anywhere when I was pinning the throttle at 6K.

Then I meet Beast here on the forum. He then convince me to get the PLX MAP sensor and explain me that it will fix a lot of my issues under 15% throttle since the MAP sensor is much more accurate. So that did fix and greatly improve the bottom end. So now I was at a point where I had a good bottom end and top end the the mid range (what we all use 95% of the time) did suck big time. I had 2 choices. 1- going back on the dyno and hoping by some miracle that the dyno tech can find and fix the mid range or I go the next step with Beast recommendation and take the plunge for the LCD-200. Since Beast was 1-0 with the dyno tech LOL, I got the LCD-200.

Beast was there to get me up to speed and was a great help to get me started. After a little over a week and about 2 tank of gas the bike run as good as it never been. The amount of information is just insane. Having the screen itself on the handlebar is already a great help to know what's going on in real life. But been able to log data as you ride give you the opportunity to fine tune for best ponies and fuel economy! I still have a bit of "massage" to do here and there. Mostly because I can and I'm on the anal side too. LOL

The way I was able to tune it is use the TPS map at cruising range (no pressure map compensation) so both map don't fight each other... and as I get on the throttle (roughly over 80psi) the pressure map give me more fuel for an extra woop. (13.8-14.2 at cruising speed, steady throttle and 12.8-13.2 for more power)

There many ways to do it but this is the route I took and it's been working well for me so far. I would more than likely give it another shot on the dyno just to compare some numbers just for fun. There's a few bike night around here with dyno run (for tips) I might use it to tune the top end with 4th gear pull with data...lol

Thanks a lot Beast for your help! :sport12:

This place is a great resource, ain't it? It's great to have all these smart and clever and wise people around in one place :)

So after all that time & money, what kind of power numbers are you seeing from the FZ6R now?

Not quite sure. I gotta be getting close to a bone stock FZ6. All I can say is with the front end drop 1/2" and the rear spring crank at the way to 7 (rode with the wife and forgot/lasy to put it back to 5) I can't keep the front end down in 1st gear. I'll try to make it to the dyno at bike night next Tuesday... If I can make it int he upper mid 80 HP I'll be happy. Bone stock the bike is 65-70 Hp. That should be enough for my stupid me...lol

I have some sort of behavior issues with anything that go fast... : oops:

But the most important thing is... the bike run great with no burp or flat spot. Oh, no more popping on deceleration too. Just that worth the $250.00 I spend on the LCD-200!
 
I look forward to hearing the numbers, Marthy. I'd like to see how it compares to my SV650 which I had on the dyno last year. They are direct competiton so it would be interesting

That was the last run when I went on the dyno early this year. On that run the engine temp were 210F or so...

78HP @ 10200 RPM & 43 ft.lb @ 8400 RPM

But you can see on the graph the big dip from 5-8K. It's all fix now!!! :woot:
 
Glad to here the tune is coming along.

The real advantages of doing this type of tuning is all of the buttery smooth midrange and throttle transitions. Almost none of this will show up as more power on a dyno. It almost always shows up as a very happy owner.

Seems like pretty good torque numbers for an inline four! My stock SV dynoed at 70 hp/43 lb-ft. I don't have the sheet any more so I can't show you the graph.

The 6R end up to be a very nice everyday machine. It got juice right at 4K all the way to 12K (limit at 12500) It's a fun bike to ride... and still get in the mid 40 MPG. (need to confirm that on my next long ride... with the latest tune)
 
I wish they can reincarnate that bike and reuse that beautiful frame, underseat exhaust design and beef up the current FZ6R. IMHO, they should have just slapped the FZ6R fairings on the old FZ6, kept the dual headlight, swingarm, retuned the motor for more midrange. I just didn't get the point of discontinuing a successful motorcycle (outside USA atleast).
 
Why didn't you get a used one? I've seen clean, stock FZ6s asking under $3000. Low mileage, poser owned, etc

Because it was one of those Saturday afternoon where I stop by the stealershio with my wife just to show her he bike (went to get a battery for one of my boss bike) I had to act fast before she change her mind... lol Budget were a little tight... so I couldn't pull the plug on a FZ1...
