I have started playing with TTS and just looking at the cam analyser.  I have set it at 4, which looks like it is where it should be.  But also there is a slight inflection at 3 as well.  I have run it on 3 and there is a definate difference in idle.  What could be the effect of running it at 3 rather than 4.  Or is 3 the correct setting.  Being it is only a very slight inflection.

 

When I put the cam info into the analyser and loaded the map, it gave me the settings of 5/2.  But running the datamaster cam recording it gives me the this.

 

 

It's 3. Cam estimator gave me 4 with Andrews 54H but analyser said 2 so estimator can be well out.

Loaded it up, so I will see how it runs this week.

My apologies to TTS, to be more accurate, it's the specs provided by the cam makers that cam be well out, not the estimator.

Ok just rode the bike to work. Starts well, runs well by ear and feel. Gear changes seem not so clunky. I will stick with this and V tune and see how things pan out. Also made some adjustments to the Closed Throttle Spark Table. After reading a bit about it in another forum I dropped the advance from 25 to 22 degrees, and to 19 degrees in some of the other columns, I will post a copy of the table when I get a chance. I was reading on another forum about the closed spark table and the consensus is that 25 degrees to way to much. it could be something to do with HD having a very lean mixture but not so sure about that..

Like you Hilly I am learning every time I pull this thing out. Read and read and look at other posts in other forums. Google is great for that... However there are so many differing opinions of what should be done. Try something out and if it is not to your liking then change it back.

Might have to chime in on this one, some of you may be aware of my heat issue so i started looking at all my settings again, I had originaly left the out setting the same as the map stated and dropped the in to make it change from 4 to 3 (as per my cam graph. 

looking further into it I believe the Se255 should be 25 in and 48 out I had it set to 23 and 40 (first one on the in to change it to a 3 and left the out as stock) reading on a few other forums I believe we are suppose to set it one prior on the in and one after on the out, so i set mine to 26 in and 49 out, its 10pm so i dont thing the neighbors would want me running the cam tune or testing (not with my baffles as loud as they are) so tomorrow will tell.

Anyone able to offer some advice (I may be slow so this may have been my issue to start with? still its all good I am learning slowly.)

Still freaking a bit about the temps every time i stop tonight it went into single cylinder mode(heat management).

What you are doing with the cam selector is telling the ECM when the intake valve is open. There are limited adjustment so you need to live with what there is there. So if the graph looks like th eone in this post I would start with 3 as the valve has opened somewhere after 3 but before 4 and that is why you see the change. My guess would be it is just starting to open at very near 4 but is already open some at 4.

not to high jack but this was my cam run,

Am i correct in thinking i need my in as 26 and out as 49? SE255 stock motor
 

You should set the IVO to 3 for the above graph.

Shadow's bike went to a dealer for a set 255 cams and came back running like a dog. The bike is running hot cutting off one cylinder when ever he stops from excessive heat. The 255 cams build a lot of heat but a few of us on this forum are thinking he has a sumping problem causing the bike to run like shit and overheat.
The dealer apparently done a comp test and got 180-185 so the cams must be timed correctly but the CCP seems low to me. Whats your call on these symptoms.

If you look in the service manual I believe it gives you the test amount of oil to check for sumping. I would do that first as that will play hell with everything else. Once that's out of the way we can move on. There were some early 255 cams that were ground wrong but unless those ended up down there and sat on a shelf for a few years that should not be a problem.

he is going to pull it apart next week so heres hoping we will get it sorted, and no they were a new order not off the shelf, I will post an up after next week.
