R6 Exhaust Marthy Edition

[Marthy]

I just like to drop a line here for the one of you with PCV. AutoTune worth every penny. This is the coolest and best learning tool for your bike. If you have a good basic knowledge of what an engine need and can do, this is for you.

I started with the TB/full exhaust MAP with the Autotune generic map. Was better but a bit "fat" on the bottom for my liking. Who need a 13.2:1 fuel ratio at 2000 rpm? Now i'm still working on it. AT can correct only 20% at a time. (safety thing, it can be change...)

what year of an R6 did you take the headers off of? I am interested in doing this mod for mine.

Accordingly to the marker on the headers, 2003-05

How much bending did you have to do on it? I am really interested in this mod. I do my own welding, so this one looks like I could do it...but the bending of the headers has me a bit confused. Is this the closest year model that will fit the best?

I have to admit that bending the headers is a B&*^! It took me longer to bend the headers than building the whole thing. The way I did it is gentely wedging a piceof wood between the oil pan and the pipe. As you heat up the headers after the bend (lower part, parallele to the floor) keep bending it down until you have about 1/2" to 3/4" clearance. Leave the piece of wood there so it can cool down in place without creating too much stress in the material. Don't try to "bend it" just put pressure down and let the heat do the job...

Just got back from the dino... 74.3 screeming ponies. I was hoping a bit better but I'm happy with that. The engine pull strong..er all the way to 12500. I gain a little here and there but the major gain comes from the 8K up.

I will call it the end of HPquest on this bike. Not a big gain but very respectable. The good point about it is for 1/3 of the price of a TB exhaust I hit pretty much the same numbers. Maybe if I got the map done on a dino it would have been better by a few hair... Ah well... If one day I decide that 74 hp is not enough I will fix that the old school way.... Cubic inches!

Accordingly to TB website dino chart:

Stock = 68.8HP Full Exhaust = 74.1HP (Gain of 5.3HP)

Marthy dino chart:

Stock = 70.8HP R6/Supertrapp (no PCV) = 68.8HP R6/Supertrapp (with PCV) = 74.3HP

I let you do the math to find out $$$ per HP difference.... SOLD!

SO basically 100 bucks per 1 horsepower . Bikes are expensive to get ponies out of , a car or truck you can get 1 hp for about $10 .

 

[Marthy]

Agree with you yellowfz. But to have motorcycle technology in a car you looking to spend at least 80-100G. Kind of very amazing to be able to get F1 technology for under 15-20G. Hey, it could have been worst. Imagine if I bought the TB+PCV... I've be looking at $250.00 per pony...

But there's more to it than just peak hp. It respond much better on the bottom end. And that Acceleration pump feature.... sweet! :thumbup:

 

[Marthy]

Here's for the one that are interested...

Acc pump feature setting:
Sensivity 75%
Rev 30
Fuel 20%

Those number have been working good for me... hope it help. :iconbeer:

I can tell you don't really know cars that well .
Just one section of a Automotive ECU is more than the whole ECU MAPs on one of these bikes , and there are 4000 Sections to a ECU in a car , F1 and better .
In fact GM just reentered the F1 circuit and are using the E67/E38 PCM/ECU available in cars and trucks .

First of all with all my respect to you, let me explain. Bike don't need that big of an ECU because they don't use 1/2 the stuff a car need. PCV is just a little piggy back controller that allowed us to adjust fuel curve, nothing else.

I never claim to know everything about cars. Especially in the electronic department. But for all the rest we can definitely sit around a case of beer and have some good talk...

Here's few pics as a resume for now. I restore this March 85-G1 from ground up. Did the whole wiring harness, ecu, lights, signals... from scratch. No diagram at all! All I had is a AEM ecu, wires and switches... I didn't do the mapping or dino stuff to be honest with you. What ever I did on my 6R was the first time I work with an EFI. But I kick ass on carbs... I'm a fast learner...

The Porsche GT3 I help building for the ALMS series, here right before the Sebring 12 hrs race. On the starting grid of the 2009 Indianapolis 500, driver Paul Tracy.

Cheers my friend!

Hey Marthy, any tips on installing and setting up the PCV + Autotune? I took the plunge and bought the whole set, to be used with the Leo Vince Pipe I installed a few months ago. It should arrive in a couple of weeks.

I think my main goal is trying to sort out my crappy fuel mileage (30 MPG give or take) and take full potential of the bike. Right now I feel the bike bogs a little bit under 4 rpm.

 

[clifford_05]

I'd be interested in this setup but don't have the tools and not quite enough knowledge to do this on my own. So kinda sucks for me but good job on the exhaust and the PCV n stuff was def a help. Glad it's working out.

My experience with PCV & AT is a bit limited but here what I learn from it. First from what you are saying, you're lean! Been there... AT is great but it can be a PITA also. It want to lean at the bottom end all the time. Probably cause by coasting with throttle close, not sure. So in a perfect world you need to rev up grab the clutch, close throttle and slow down.

Mark you throttle with a white pen for reference (10%, 15%, 20%, 40%, 60%, 80% and 100%) use your laptop to do it. Don't forget to go in setting and configure your throttle, you should see 0 when close, and 100 when all open.

So from idle (use 2nd gear) open the throttle steady to each of the mark you did up to 12500 rpm, grab the clutch & close throttle immediately. Don't let the engine rev down "engine brake" Plug in your laptop and accept trim in the top menu (tool, AT, accept..)

Not quite sure witch MAP you should use to start. There's 3. Stock pipe, M4 or TBro. None of them was working for me, so I use a blend of M4 & TB. Easy to do. If you know how to use Excel, PCV work the same way... Copy & Paste! So let say by example that you are happy with the bottom end of M4 but AT want to lean the top end. when you accept the AT trim it's for the whole MAP, you can't select just one section. (sucks) So what you need to do is accept the trim, save the MAP on a different name "B". Copy & Paste what you like back in MAP "A", save in MAP "A" (or "C") Send back to PCV. Sound maybe a bit complicated, but after you do it once or twice it's easy!

My MAP is here on a PDF file if you want to give it a try. Don't be afraid to manually change some number to add or lean. It might run like crap but you won't brake anything. If you see any number under -10 or so= Rubish! Like I said AT will go lean on the bottom end.

Hope it help Mate! Let me know if I can help some more on specific question. Just keep one last thing in mind. AT is not a dump proof programmer tool... read between the lines... PM your email I will email you my MAP. Actually if I end up to build a few pipe I might try to post my MAP on the PCV web to download. (Supertrapp)

Hang out here my friend. I'm in the middle of building a second Supertrapp out of the stock headers. I'm still waiting of few goodies from UPS. Since I'm not expecting everyone to like the Supertrapp set up I'm thinking of getting a Viper can for measurement. So you were be able to have 2 options. I'm trying to find another stock pipe for cheap to do the other one. I will go thru the same drill with the Viper Exhaust when I do it... I will double check the MAP with AT to make sure everything work fine.

Don't worry, the PCV is very easy to install. Few connectors, velcro and few zip ties... You have enough tools under the seat to do all the rest. Well, the block off plates sucks... but you can just plug the hose at the airbox, it work just fine.

Anyone interested into a megaphone exhaust? LOL I just can't imagine how loud it would be!

I'm still debating if I want someone with the skills, because I have no tools in this state, to alter a set of 99-02 headers i have to match closely to TBR headers so I can utilize different slips-ons. I also thought about altering my factory headers for the same purpose. One thing you have to remember is that various mufflers have different in-lets to out-lets where they slip on. Most commons are 1-3/4" and 2". A adapter would have to be crafted.

I was going to standerize it at 2" inlet. But it can be customise to your need. I welded mine directly on the pipe for 2 reasons. 1- wasn't crasy about the look of the exhaust clamp, even if it was the nice model. 2- I needed the 1" or so to stick the can all the way underneath. Keeping it clean and underneath was my biggest chalenge. It was one unique feature of the 6R that I wanted to keep.

I am also another one that doesn't have the fabrication skills do to this on my own, but would love an exhaust for my bike. I am not really down for spending a ton of money on a TB, which is why I was looking into the M4, but that is pretty expensive too. Would be interested if the price is right, and the look is what I could be into.

The only two cheap options are Supertrapp and Viper. Unless you want it straith pipe and figure it out yourself... I'm going to order the Viper can today so I can have everything together sometime next week. Kind of hard to put an exact number right now. I think if I have some demand I can get it done at a fair price. Doing it with the stock headers will cut on labor time by a lot. Give and take without shipping I'm looking at somewhere around $375.00 for the Supertrapp and $425.00 for the Viper. (using your own stock pipe) That will include a fairly decent MAP to go with it. I got the MAP pretty all sort out on the Supertrapp. Some of the Viper owner are using the M4 MAP, but since I have the AT all hook up,I will weld an O2 sensor adaptor on the first one I build and double checkto make sure it's as optimal that I can get it. And yes, I'll run it on the dino... the same way I did with the Supertrapp setup.

Just ordered the Viper can and allthe goodies to build a second pipe...

I thought that they Supertrapp looked awesome. Are you saying that we should get the PCV also? That would add to the cost of the whole thing. But I would be interested in that definitely.
