Is it necessary to have the cam specs on when doing a dyno. I recently installed a upgraded cam on my M8 and took to place for tuning. The tech said he needed the cam specs. I called the place and where I purchased cam and the person wouldn’t give me the required info. Cam came with some info on a card but didn’t have the IVO specs or IVC. Using a TTS tuner. The guy said if tuner knew how to tune he wouldn’t need the specs.

The cam specs should be online.

Nope not for this particular cam it isn’t. Bought it from Jim’s VTwin performance. It’s a Maxcell 821H. Called the guy and won’t give me the specs. What an A hole
-
Put the cam you need specs for on a online search and you will find what is needed... Or what cam and I will give you specs.... The tuner should know how to find this information.....
-
Disregard my post!!!!!
-
Cam specs are helpful but certainly not required to tune the bike.

OK kinda figured but the tuner wanted some more info on cam than what came with it...I'am gonna find someone else now.

All he has to do is do the cam timing in the DATA collection. Using the cam specs in the software only gets you close.....the Data collection still has to be done.

Can i just use the cam tune in TTS to get specs. Can it be done just idling??

The Cam Tune will not give you specs, it will tell you when the valve leaves the seat and when the valve closes by graphing the Cam Tune in Data Collection. You will be shown on the cam graph where the line breaks.....either 1,2,3,4,5,6, or 7. After you find what number the cam tune breaks you slide the bar to that number and down load to map. Do the same for valve closing.....read the instructions in the PDF Tuning files.

Jim won't share any information about his cams specially the M8 cams also you will not find any information online, as stated by Doc1 your tuner can do timing in the data collection.
anyway, this is the best cam that I have seen for 114 & 117 as direct bolt in, hp&tq curve are flat with right pipes you should see 120/130

I'm running a D&D header pipe & stock CVO mufflers with 2" fullsac baffles. Guess his cams are so much better than anyone else's he can't publish specs. Oh well guess that's his right to do so...

Have seen Jim's and the TTS cams where mftr refuses to share information. Mftr can keep proprietary what they choose. It's their right. It's enough to keep me from buying from them though. I want to know what's going in my engine. I admit I don't need to know and that a good tuner doesn't need the data to make a good tune. It's probably just me being a bitch. If I buy the product it's not too much to know what it is. We're not talking special proprietary materials or methods here that the rest of an industry couldn't replicate. It's just lift and duration and they (the companies) just aren't as special as they seem to think they are.
I was always the same way with dyno shops that wouldn't supply a copy of the tune. If that's their position they don't get my work. But, then again, at least three people in the world have said that I'm an asshole.
-
If you just gotta have the data send the cams to someone with a cam doctor and plot the cams. Then you have all the info
-
If the seller refuses me the data, I find another seller. The cam guy has nothing special, he just wants you to think he does and not be able to learn it yourself by comparison. if another Cam company wants to duplicate they would buy a cam and do it. But I want the specs. They cam specs mean something to me, always study them extensively before buying and compare with similar, may be incorrect in the final decision but it is my decision not some big headed cam grinder.
This opinion has resulted in TTS loosing more than one sale that I know of, and I am not talking cams here. But like Twolane said at least three...

I have a turner that knows my expectations and my riding style.
He’s done my bikes for years and I’ve never been disappointed.
My engine builder I’ve used since the 80’s and he knows what I want, never disappointed there either.
I hope they both outlive me!
The cams can be made of wood, I don’t care. The end results are what I’m interested in.

TTS175 can be considered as well both cams has flat curves, TTS wins in the TQ and Jims in the HP..

Here’s my take on no releasing this information. So let’s backup a step and let’s plan an engine build using this cylinder and these high dome pistons and OH! Let’s stroke the motor to throw in some real craziness. You NEED this cam information to know how the timing and compression is going to end up! When your planning cam timing and air flow and exhaust restrictions needed to get a certain amount of air into the cylinder, you need this info to plan a build. To not give this to you precludes you from using their cams in this example.
Just my two cents.

My experience was to set my goals first and what size of engine would get me there.
Went to 124” on my M8
Called TTS and talked to Steve C with the kit I was interested in, what bike it was on, my riding style and load.
He made a few suggestions on parts, recommended a cam AND local tuner nearby.
Tuner guy said it was easy to tune and came in nicely. Chart reflects the same.
Got my goals, bike runs verrrry nice.
We checked fitment, installed the package of parts, went by recommendation from the 2 suppliers that have done hundreds of packages like this, I’ll let the pros suggest parts as long as they understand MY goals.
I was on the fence with a tts250 or 200 cam, settling on the 200 to fit my style. Couldn’t be happier.
Completely different from my hot rod bike but what I needed for the long rides.

I know it rubs people the wrong way. This is why we have choices. If you don't want to buy a TTS cam then its ok there are many that publish specs. I did a build with a tts 250. I knew the compression needed, best fit as far as engine size, and lift gross and tdc after a call to Steve. This is a 126, was a 107. I just followed Steve's lead. Blip near 2000 is the tire slipping on the drum. Hitting 140tq right off idle does that.

Yup, there ya go!
Nice flat torque curve also.
