Keep in mind that rub's do not necessarily require sugar, other than to help balance the salt/savory content. If you cut back on sugar, you can probably cut back a little on the salt as well to maintain balance. Try using use your favorite recipe and just delete the sugar, You'll probably never notice the difference. If it seems just a little too salty just reduce the salt as well next time.
Here is a collection of sugar-free, low salt (some salt free), or alternatively sweetened rubs previously posted on The BBQ-Brethren.

http://www.bbq-brethren.com/forum/showpost.php?p=2946414&postcount=9
"A smooth blend of spices with no sugar. A tablespoon of cayenne gives this rub a good wallup".
1/3 cup salt
1/4 cup paprika
3 tablespoon chili powder
2 tablespoon black pepper
1 tablespoon ground cumin
1 tablespoon garlic powder
1 tablespoon cayenne
Combine all the ingredients in a sifter, and sift to blend well. Store in an airtight jar in the refrigerator for 2 to 3 weeks or in the freezer for up to 6 months.
How to use it
Sprinkle this rub very heavy on your brisket, ribs, pork, chicken or fish. This rub can be used on both grilled meats and barbecue cooked over indirect heat because of the absence of sugar in the rub.

http://www.bbq-brethren.com/forum/showpost.php?p=2095320&postcount=8
2 T butter
1 clove garlic or 1 t garlic powder
1/4 c. finely chopped onion or 1 T dried minced onion
1 T lemon juice
1 c. tomato sauce
1/3 c. Splenda
1 T molasses
2 T Worcestershire sauce
1 T chili powder
1 T vinegar
1 t coarse ground black pepper
1/4 t salt
Combine all ingredients in a sauce pan and bring to a boil; reduce heat and simmer for 5 -10 minutes, stirring occasionally; remove from heat and let stand. I usually double the batch and keep some in a pint canning jar with lid in the fridge - it will keep for a couple of months if you can sty out of the jar.

Low-sugar Central Virginia Barbecue Sauce by Boshizzle's
1/2 Cup Shack Sauce
1/2 Cup Balsamic Vinaigrette
1/4 Cup Low-sugar or No-sugar Ketchup
3 Tablespoons of Worcestershire Sauce
Juice of 1/2 a Lemon
Stevia to taste (optional)
Add all ingredients to a saucepan except the lemon juice. Whisk while heating over low heat. Do not boil. Heat the sauce while whisking it, long enough for the jelly to melt. When the jelly has melted into the sauce, remove from the heat. Add the lemon juice and mix well. If you use artificial sweeteners, optionally you can add Stevia (or your favorite artificial sweetener) to taste.

Famous SHACK barbeque sauce recipe (Little Rock, Arkansas): - BBQ, tasty, tangy, and unforgettable.
https://www.bbq-brethren.com/forum/showpost.php?p=2159787&postcount=3
Wet Stuff
Mix in a large bowl:
3 - 24 ounce bottle of ketchup (catsup)
Use the plastic ones, we will refill after making sauce.
Fill with hot water, swoosh around and dump contents into bowl.
Folks have asked: HOW MUCH WATER? Fill all three bottles, and dump all into 'Wet Stuff'
(For original recipe use Grapette from Wal Mart- see 'additional notes').
Pour in plain ole cheap vinegar. "THE" recipe calls for just less than a quart, do not sweat this. use anywhere from a pint to a quart, strangely, this amount has scant effect on final product.
Put "wet stuff' in a LARGE pan, put heat on "high"
by the time it is approaching a boil, you will have "dry stuff' prepared.
Dry Stuff:
Since you dumped wet stuff out of bowl, why not use for 'dry'?
Into bowl, dump:
1 - 4 ounce can of chili powder
1 - 4 ounce can of black pepper
1 - 4 ounce can of garlic salt (SALT, NOT garlic powder!!!)
1/2 cup - sugar (is the ORIGINAL amount, why not TRY that, and adjust to your very own taste after 'brewing' mess up...likewise with Tabasco. See below)
1 - small Tabasco (anywhere from 1 to 4 ounces..start with about 1 oz...you can 'play' to taste after whole mess is completed.
1 - small mustard (size of an apple, just regular ole smear on a hotdog yeller mustard)
Stir
...btw, easier to put the mustard in last, and just swirl around till it looks like chocolaty brown tar.
Simmer
Dump all this stuff into pan on stove now approaching a simmer if you have been quick, and if you rinsed out the catsup with HOT water;-)
stir enough to make it evenly liquid...bring to a boil and immediately lower heat to a simmer.
30 minutes, (stir fairly often to avoid sticking).. during which the vinegar will bring sweat to your forehead, and tears to your eyes...think ventilation here.
Finish
That is it.
Remove from heat, pour back into bottles you saved, unfortunately, you will have an excess of sauce. Improvise, all life has dry rot.
You now have a LOT of sauce. I always do, and find it MOST welcome as a gift.
BTW, there is no need to refrigerate your sauce supply, even if you inhabit hot and humid southern climes! Apparently mischievous microbes refrain from causing problems in gratitude for being immersed in this tomato based necter, or are immobilized by the ingredients rendering them deliciously inert.
Additional Notes
Do it this way the first time, later, you may substitute Grapette, for the water (seriously) SHACK DID for several decades ... for total authenticity you can obtain Grapette from Wal Mart
I add about a cup of sugar to my sauce, but this is heresy, and practice has strong adherents and detractors.
Likewise minced onions, NOT authentic, but can be pleasant.
Do NOT futz with the amount of black pepper. I KNOW it sounds like a lot. Trust me on this.
Also remember garlic SALT, not garlic powder!! several folks got this wrong, actually the sauce wasn't bad, but they were not fit as shipmates for WEEKS.
Do NOT judge 'heat', as in taste, by sipping off spoon from pot, even if you were stingy with the Tabasco. Dunk a piece of bread into sauce and sample that way.
