PCV Map for TTS-100 cams?

[Dr. Joe]

Got my TTS-100 cams installed the other day, as per Mr, Wiz's tutorial and now I want to re-map my Power Commander-V, only there is no suggested map for this cam. I've got the SE1 air cleaner, de-catted stock exhaust, and Rienhart slip-ons. Any suggestions?

No hurry as I'm still in the "as long as I've got it down this far I might as well.............." stage (service the forks, new handlebars, some powdercoating, new gauge faces, shine up the inner fairing, swap the air temp gauge for an air ride gauge, etc, etc) ................... thanks

How about changing to a TTS master tune?? Versus Power commander

 

[Dr. Joe]

I guess it all boils down to $ and if spending another $450 to replace a tuner that is already capable of achieving the results I'm after makes sense. After all, they are both fuel management devices and capable of getting the right fuel mixture for my riding style. Also, I can get the trike dyno tuned for less than $450 if need be. Thanks for the suggestion though. Once I get the trike back on the road I'll take everything I learn from this forum and decide on the best route to go.

Thanks again for the reply!

Have you tried Jamie at Fuel Motto, I would think he would be able to come up with a map that should be close.

Dr.Joe, this has been one of my negative issues since this cam came on the market - No information at all just a "this is a good cam, trust me"!! I tried to obtain the cam specs when it was first mentioned and was told they were not available unless you purchase one. Don't know about you, but I would not purchase a cam without reading the specs and making sure it was compatible with the rest of my build components!

In any event, good luck with your search. And Jamie at Fuel Moto is where I would start, he is very helpful and extremely knowledgeable. First rate vendor!!!

[Dr. Joe]

Thanks all for the great replies! Contacting Jamie sounds like a great plan. And for FuzzyWuzHe, the Power commander has an Auto Tune add-on option for about $240. I don't mind the learning process with all this "new fangled stuff" as it's helps to keep the ol' grey matter active. One foot in front of the other and eventually you wind up where you want to be...

Thanks again y'all!!

Good Info on this thread too..

 

[Dr. Joe]

That's the thread I followed that convinced me to try the 100's in the first place. Here's a link to another forum on the TTS-100 cam and from the looks of it someone figured out a way to come up with the cam specs for the 100. I couldn't open the spec pages for some reason, but maybe someone else can.

Thanks a whole bunch! This is just for the tts-100, right? Can you bring up the 255 for comparison?

There are both on that paste.They are side by side. It may have not come out correctly

[Mr.Wizard]

The cam information you got from HT is incorrect.

Go back to post #28 where TTS tries to tell everyone.

The only place to get a calibration for a TTS100 cam is by purchasing a TTS tuner or you can just download their software and copy the tables OR you can use any calibration for the 255 cam. Not exact but close.

So what if you had the real specifications? How do you think this would help you?

I ask these as serious questions because what most of you do not understand is there are NO standards followed in the HD world of giving specifications on TC camshafts! Another thing one needs to understand too is that just because you see numbers on a piece of paper for opening and closing it has nothing at all to do with when the valve really opens and closes. Proper tuning requires that you know when the vale truely opens and closes not the BS you read on the internet.

Take a look in a HD catalog and look at the specifications they give you, then real the very small foot note down on the bottom of the page too. It says "based on a theoretical rocker ratio of 1.65" for all there Twin Cam camshafts. Only problem is there is NO such rocker ratio that has ever been used on a Twin Cam engine. In this industry some use a ratio of 1.63, 1.64 and 1.65 so comparing the specifications given on a web site or a piece of paper is a waste of time at best. Then, we can move on to lobe design and look at the differences there too, which do not show up on a camcard and will make the engine run completely different.

Just think about putting a point down on a piece of paper and it cannot be moved. Lets call that the opening point on the camcard. Now draw a flat line through that point in any direction you like. You will come up with hundreds if not thousands of lines you can draw and NEVER move the point you started with. Now move on to curves that will go through that point and you begin to get my point.

So with out all the supporting information a camcard set of numbers tells you little to nothing and it's just another old wise tail the way its been done in the HD Twin Cam world, Sad but true.

We've sold hundreds of these camshafts and to date, not one dis-satisfied customer out there, with how they perform. All in all it does just what we said it would do, and many times, more than we claimed! If you have a question about a build and using our camshafts (as there is more than one) just give us a call and we will tell you if it right or wrong for what your looking for.

and there ya go... From the horses mouth to your ear.

 

[Dr. Joe]

Thanks for your explanation Steve. And thanks for all other responses as well... it's all good!

Just curious if you decided what to do. I do have a PCV with auto tune and TTS100 cams. If you get info from Jamie it should get you in the right direction. But I couldn't get any info except from Steve Cole, which I am running much better, but it was trial and error. To do all over again I would have the TTS Mastertune. I had it dynoed several times. Wasn't happy with it, after Steve's comments I changed the timing on the PCV to what I thought run better. My engine is not stock. The auto tune shows me a chart and gives me a idea how it is running. Just so you know I had the PCV with auto tune to start with. Good Luck!

If you will run & record a log file then send the tune file & the log file to Jamie at FM he can make the changes that will get you much closer to what you are looking for. This is of course if you purchased your PCV from FM.
The TTS & the Power Vision are both much better than the PCV.

 

[Steve Cole]

The PV unit, regardless of model, does nothing much to help you with timing. Adjusting the fuel is only on part of the bigger picture when it comes to how a engine runs. People need to be aware that any engine modification requires you to have some understanding of what's involved in the tuning side of things and just having a cam card isn't going to help that at all. There needs to be a balance and we're here to answer any questions we can to help you get there even when it's not our tuning device being used.

You say you had your trike dynoed several times without being happy with it? Was the operator a DynoJet tech? Reason I ask is I am planning on doing a Dyno tune with on a DynoJet rig with a DynoJet trained tech. I was under the impression that having an engine Dyno tuned is the ultimate way to get EVERYTHING right the first time. Could you elaborate on your Dyno issues?

Steve... So should a good Dyno tune be the BEST solution for anyone without your Mastertune? A buddy of mine is waiting for my impression of the TTS-100 cam and he has a PC-V as well and I want to make sure I can steer him in a direction that doesn't involve the research that I, and others, have had in regards to this cam.

LOVE the cam, by the way!!!!! Tons of torque at the lower RPMs and it keeps cranking right up to the limiter, and this is even without the fine tuning!!! But I can tell there is even more to this cam than what I'm experiencing so am looking forward to getting it tweaked very soon.

 

[T.P.]

Dr Joe,

I don't think the dyno people that dynoed mine took the time to do a good job. When reading other posts, I think it takes much more time than they put into it. I do think a good dyno is the way to go. In my case it just didn't happen. My trike is a CSC which is wider than most, and nobody had a wide enough dyno. The dealer I went to removed the side plates and changed tires to make it fit. But I wasn't happy with it. I played with the fuel ratio until it was running better. This is where Steve Cole helped. To do it over again with the PCV and auto tune wouldn't happen. This is just my experience, you may have much better luck with a good dyno.
