Vacuum Reservoir or Not on Audiovox CCS-100

[skidgillen]

I am currently installing the Audiovox CCS-100 on my ST1300. Should I install a vacuum reservoir or not? If I do, what's works the best? I made one like GitSum's but cannot see how he routed the vacuum lines completely.

I’ve installed 2 of these, and used vacuum reservoirs on both. I put the servo on the left, in the area behind the “grill” in the dash. The reservoir went in the same location, on the right side.

I have installed 4 and did not do a reservoir on any. Does it hold speed, yes. Does it loose going up a hill, yes, but so does my car. About 3 MPH is what I see. I guess to see if it does make a difference would be to get 2 bikes side by side and do a real world comparison with the exact same conditions.

It does not hurt to add one, if you so desire.

I used a reservoir on my installation and it would maintain speed perfectly on hills, even when at high altitudes. Before I installed the reservoir it would slowly loose speed on hills. The longer the hill or the higher the altitude the more speed it would loose.

Reservoir hear it maintain speed up hill no problem plus one on the reservoir

I've done 7 installs and all had reservoir. In the midst of installing the electronic Rosta cruise.

I'd say reservoir on an ST, but it doesn't have to be too big. I used a metal fuel filter (just because I didn't like the idea of plastic, just me) and it was maybe 1.5" dia by 2+", very compact. Alternately, you can coil up a bunch of vacuum hose....

1 with and 1 without. didn't notice much of a difference..

I did notice a a positive difference when I changed the dip switch setting from light vehicle to heavy vehicle .

 

[Stew1300]

+1 on the reservoir, no loss of speed on hills

 

[skidgillen]

I'll probably do the reservoir. Thanks for the feedback everyone. Now I gotta tackle the brass stud on the throttle that I stripped a couple threads off right when I was using threadlocker and finally getting it where I wanted it. Ain't life grand?

 

[skidgillen]

Got throttle fixed. Now back to vacuum. So........Servo to Vacuum reservoir to Domed side of check valve, and the 2 other sides of check valve to Map sensor and throttle bodies??????????????

why dont you go with the rostra electronic cruise. No vacuum cannister needed.

Because I found an Audiovox one on ebay for $100, new in box.

Rostra kit is about 250. So not too much more and the overall install is a lot simpler. Fully electronic. Just a thought.

Here's some more reference material if you need to trouble shoot. http://www.st-riders.net/index.php?topic=8170.0
I have 3 vacuum points that are teed together with one way valves.(mines an 1100)
I found this too to be of great help in setting the dip switches. http://www.valkyrieriders.com/shoptalk/cruise-control.htm again it's a carbureted bike, but some of the install applies. I would stay away from any of the scotch connectors that are provided and use positap ones instead or solder and heatshrink.
A very good price at $100 and well worth the effort to install.

Went for a test drive today before putting the cowls back on and the cruise will not set. Electrics all check out. It is either a vacuum problem or binding of the cable system against the airbox snorkel which I shaved down as much as possible. I'm thinking the 3 way check valve because it will let me blow air on all three ends without restriction. I was really hoping to have this project done by now. Oh well, supposed to get at least 2 inches of snow tonight anyway!

the cruise will not set

Do you by chance have LED brake lights? If so, it will not set without a relay modification to simulate an incandescent bulb. This Relay wiring diagram can be found on Murph's web site. He is marketing the CCS100 under his brand.

If you are thinking the check valve, do you have enough hose to go direct from the canister to where you tapped into the vacuum line. Bypass the canister and check valve to test the function of your wiring and unit.

 

[RaYzerman]

To add, there is a cover on the servo unit which has indicator lights so you can test the switch functions......

I pulled the led bulbs out before hand and replaced them with regular incandescent. I do have LED hyperlites tied in as supplemental but I don't think that's it. I pulled the cover off of the bottom of the servo and checked the led for all the functions, i.e. tach input, brake light disengage, and set and accel switch inputs.

I too have this set up on the 03 that I am selling and the 07 that I bought and installed the CCS100 on. You are correct that LED's tapped into the brake wiring to operate them should have NO effect on the unit setting.

The next step? Aren't these things fun.
