Camshaft specs... The next project!

[Hellgate]

Here's my FZ6 plot on a Factory Pro dyno. The red trace is with a DynoJet map, the blue trace is with the tuned map.

Note the very bottom traces are % CO, note how fat the bike was prior to the tune.

The only mods on the bike are an Akrapovic slip-on, the Power Commander, and the tune.

As they say, "Lean is mean!"

Note: For you numbers guys add 17% to get typical DynoJet result numbers.

Marthy FZ6R. First start up with FZ6 cams swap! - YouTube

You def have to set up to stay in the DC area for a day or two while you're are passing through the next time.

Sounds awesome and glad she fired up the first time!

Well, first impression... I started with Avgear RebB and it went good but felt like the bike was running fat a bit. I loaded the zero map for a quick spin around the block and much better! I'll do few phone call around... I might just get it done on the dyno this time. I'll give it few days... so far so good.

idle to 4K feel like it pull like a BMX then 4-8K is better than stock. Over 8K need more tuning... I'll get there.

Something I have seen on cammed cars and trucks , it smells richer but it is actually is leaner be careful (especially without CATs)
Without a wide-band it can be deceptive , of course with your extensive racing history you already knew that .
For others benefit .

For the stock FZ6 its fat. After a good tune, "leaning" it picks up about 5 to 7 on top, and about 8 in the mid-range.

Check out the tuning centers in Florida listed on the Factory Pro site.

Factory Pro: Producers of the EC997 Low Inertia Eddy Current Dynamometer Series and Quality MC performance products

They list Full Spectrum Racing, Atlantic Cycle Service, Two Boys Racing and Phoenix Motorcycles.

Have fun!

Thanks! 2Boys are the closest to me. I'll give them a call next week. The hard part is to tune the A/F ratio and the cams at the same time. So I need to rough in a map that work good enough to get a base line on the dyno. Once I know the HP/Torque curves I might need to move things around to adjust the curve where I need it. I'll be very surprise that I hit the sweet spot on the first try...

As of right now the mid range seams much better, definitely where the gain is the most noticeable. (4K to 8K) Pass that it still respectable but I need to figure out if I'm falling off the cams or it's fuel related. I can't feel that on a 15 minutes ride in traffic...

I'll go for a nice ride over the weekend with the laptop in the top case... lol

I have the PCV with Autotune. This is actually a Wide Band sensor in the exhaust... You put the A/F Ratio that you want and it gives you the correction. But in real world, it's a POS! Work alright at 80% and 100% but as soon as you coast or rev down it tell you to lean the crap out of it...

Yeah data logging is fun .

Yeah a BEN MAP is much better for AFR (EQ , Lambda) tuning , it logs acceleration and deceleration all in one MAP , plus PE (power enrichment) and you can filter transient throttle movement .

Do you think you can make enough compensation in the ECU MAP to make up for the rest ? Is there anyway to load a new MAP into the ECU , I know the PC just does fueling (injectors) . Thinking out loud .

You can get the ignition PC for another $300 or so. It connect with the existing PCV then you can tune fuel and ignition together. Not quite sure I want to get there... but if I have too, I will. Since I barely spend $130 for the cams mod... (Cams $50, Cams gear about $50 and machine the cams gear $40)

Something like this ; Motorcycles | MotorSport ECU Tuning | Flashing | Remapping | Chip Tuning – ECUnleashed Tuning Technology: The Go To…To Go Fast Company
But I want to see the MAPs and be able to change data for myself .

Did a bit of riding tonight. Running really good. I'm impress with the mid range and still pull really good all the way to the rev limiter. I'll try to swing back at the dyno for a quick run like I did last year at the stealership. I went very conservative on the cams timing and try not to kill the mid range... maybe I went too strong? I need the dyno run before anything. The Map look like ok for now. To be honest, an exhaust and cams mod without PCV will not be that bad... Autotune is barely correcting the zero map...

And one thing I did notice tonight... no popping at all. I try hard, still no popping.

Roughly how many horses u reckon you will get out of her??

I think everyone is waiting for that bit of info .
I didn't see Marthy saying anything like ; Holly Crap ! Or , it pulls the front wheel off the ground with just a twist of the throttle , yet .

Marthy I have seen it with cars and I a sure you have as well , AFR that the PC commands is just injector pulse width so I doubt that changed that much with cam install , larger injectors , yes it would then .

Of course using E10 you would be better off tuning at 14.12 AFR (middle of the road so if pumps are not exactly E10 , which is a likelihood) or even 13.89 AFR (exact) more real world numbers for E10 .

The PC is just doing fuel and not cylinder mass , timing or other things that influence the engine tuning , limited resources trying to gain from a single tool , not that it is a bad thing , just need more than the PC I would think to get full potential .

14.12 would be safe for cruising, but way to lean for WOT conditions. Most engines tuned on pump gas shoot for 11.7-12.5 afr under WOT where you will see max hp.

I'm local and stock, almost broke in, (another 400 miles till I feel broke in.) I can't say I'm an excellent rider, but if you feel like setting a day for PBIR, (after you get 100% dialed in,) we can see how you do compared to a completely stock FZ6r, that's added a few pounds, (180 pound rider,) with an added sw motech center stand.

I figured he would know that was not in WOT conditions.
Actually 12.8 to 13.2 for NA , you are in boost with that rich , 11.7 , unless you are compensating for the E10 , 3 to 4 percent difference.

To rich kills power just as to lean will.
Seen it time after time lean makes more power.

To Marthy,
I'm still sitting on those YSR R6 throttle bodies and the offer still stands. Yours for the cost of shipping. I kept them just in case you ever needed them as I've been following this thread.

Think a lot of people are following this thread to see where he can take the FZ6R

The Auto tune is set from 13.8 to 13.0...

I bought a set of FZ6 TB also. But I don't think I will install them. The intake port is not any bigger and I will need to do a lot of "match port" to get it to work right.

Just an update for the ones that are interested.

The MAP is getting close enough for a good base line on the Dyno now. I can tell right away that I might need to move the cams around a tinny bit. As soon as I hit 4K the bike comes alive. The mid range is just amazing! It still pull all the way to 12500... but doesn't have the top end rush that I was expecting. I did time the cams on the conservative side, since the 6R is short of 2K RPM compare to the FZ6. I could move the cams right away, but I want to check how it ends up first. I'm more interested in overall performance than peak HP.

So as of right now if it was the best I could do I will still be very happy with this mod. If you are mechanically up to the task, this is the best HP mod per $ by far! I'm planning the Dyno run Thursday or Friday...

Can't wait to see it!
