Pulse specs question

[arcticbreeze]

My 70lb/28" Pulse is confusing me a little. I have been playing with this thing and I am not sure where to go. I am not to far off but dw is concerning me a little and my DL is Long. Here is what I have:

74.6 lbs peak weight with limbs maxed minus 1/4 turn
14lbs 3oz letoff (approx 81%)
34 7/16 A2A
6 3/32 BH measured from deepest part of the grip to center of the strings diameter
28 9/16 DL with 28" mods

From everything I have read most important would be peak weight, draw length and holding weight. Below is a quote from a post by Armstrong13.

Here is a list of tuning variables, in order of importance, for all the 2011
bows.

1. Peak Weight +2.5 lbs/-0.0 lbs
2. Draw Length +1/16" to 3/8" depending on model and mod
3. Holding Weight - should be no less than 80% and in most cases much
more
4. ATA +/- .125"
5. Brace +/- .125"
6. Speed Rating (taking into account chrono variation)
7. Orientation

Basically, if your cams are synced and numbers 1,2 and 3 are in spec the
bow will be in it's optimal tuned position no matter what the orientation is.

So I am already 5/16" long on A2A and if I take twists out of the cables to reduce peak weight that will lengthen A2A even more or if I add twists to the string my DL which is already 9/16" long will get longer. I have read that most find there sweet spot at about 1/4" long on DL and that would be perfect for me.

For you guys that have tuned a few of the Pulses:

Are you finding peak weight that high after tuning?

On average where are you +/- on DL

Are You finding the A2A to be long and if so how long?

If these were the specs on your bow what would you do?

Thanks in advance from a guy still learning.

I would start by taking a couple twists out of the cables...also I am wonder if you got one of the mods that the draw stop slot is not long enough. The holding weight on my Pulse is 10# 72# DW 28.5in DL.

Twisting the string reduces dl, dw & ata, but also adds to bh which you don't need. I would pull the strings & set them to spec, hopefully that would get you to a better place to start. I'm holding at 8lbs w/ a 60lb pulse 1/8 long.

I have a 28/70 Pulse also. It sounds like you were trying to get the tuning holes in the right spot from the limbs like I did. Don't worry about that.
Put 6-8 twists in the string. This will drop DW and shorten DL and ATA and BH. My Pulse is 1/4" long DL, 72-73 DW. ATA is 34 1/4". My letoff is also 80-81%.
Ulitmately the peak DW at 6-6.5" into the draw is the key to preformance.
Put it on a draw board after you twist the string and check peak.
Chrono is hitting 321fps.

Twisting the string reduces dl, dw & ata, but also adds to bh which you don't need.

I am confused about this also, the tune chart also shows my BH should have gone up but it actually went down. Has anyone else seen this?

Twisting the string will decrease BH.
I thought I taught you better Dave.... LOL!!!

Twisting the string will decrease BH.

That is what I experienced but the "Cam Tuning Basics" from Elite say just the opposite.

After twisting the cables I ended up at 72lbs 2oz peak wt and 13lbs 1oz holding weight. The DL did go up a little but it feels perfect. I am very happy with the results.

Thanks again for your help.

Sounds good. Glad to help.

That's the problem w/ our education system, the kids just don't listen

Wow, I added 6 full twists to the string and this is where I am at now:

71lbs, 4oz peak weight @ 6 3/8" into the draw cycle
15lbs 6oz letoff (approx 78%)
34 3/8" A2A
6" BH exactly measured from deepest part of the grip to center of the strings diameter
28 1/16 DL with 28" mods

It looks like that took it a whole lot closer.

Should I ignore the long A2A and add a twist or 2 to the cable to increase the letoff?

Another question, I hit my lowest holding wt number with the draw stops about 1/32" before touching, this is with them back out all the way. After getting everything just right should I draw the bow on the draw board to the lowest holding weight and move the stops in?

Thanks
