Hey guys I bought a sigma last week and I am so glad I bought it.  It only cost like 25 bucks before shipping but it was worth every penny.  It was an easy install.  All i needed was some EARTH MAGNETS from Radio shack.  They are so strong they wont leave my rim even thoug only 2 are glued on , a total of 4 were used.

Anyway here are some pics

the sigma sensor under the front fender, the rust is the magnets.  U can only have less than 1/2 cm of space between the two.

http://www.bikepics.com/pictures/402323/  I noticed the Sigma didnt have a light and couldnt use it at night.  I bought a book light from CVS for 5.99 and mounted in on the gas tank with double sided tape.  Now if I want light I just flip it up and close it to turn it off.  It works great and is adjustable, plus wind doesnt bother it.

this is a pic of my bike with new tool bag.  check out my funky filter..  I am thinking of putting some white led's in my saddle bags so at night I can see whats inside before I put stuff in there and ect.

Nope it isnt.  I heard wireless wont work becuase of interference with the alternator.  It makes sense too.

hey,

So what does this sigma do?

also, in one of the pics i see a helmet in the back with a netting.  Is this some way of securing it in place for driving, so that you have a passenger helmet?  Where did u get it and how does it work?

thanks,

Weez

what kind of a net was it and how is it attached to the bike?

I just installed a Sigma computer too. It is a nice toy. Here are some speed comparisons.

Savage Speedo              Sigma
    KPH                                      KPH
     
                     
    50                                 50
    60                                 62
    70                                 74
    80                                 84
    90                                 95
    100                               106
    110                               118
    120                               130

These comparisons are not what I was expecting. Later tonight when my wife comes home, we will go onto the divided highway and do a speed syncro with her new CR-V. I am not sure what this will prove, in fact it may just confuse the issue. This reminds me of a Confucianism. " Man with two watches never knows correct  time."

The CR-V at 100 KPH registered 104 on the Sigma, and at 120 the Sigma was 124. These speeds are probably more realistic.

I Just received my Sigma Meter and seem to be having a problem setting it up. The install was easy enough. I used Jim's idea of the rare earth magnets. My problem is I cant seem to get the wheel numbers right. I measures the circumferance and came up with 80 inches (2033mm) but when i enter the number i am reading 30mph at 20. Does anyone know the actually number used for a new S40 that is all stock?

yeah I would use my number or remeasure.    If it was too big then the sigmas readings would be lower then the speedo which i am guessin is what it is happening

My reading was 2054 which is really close to Bentwheels.  Mine is a 1995 tho.  Check your speed at 60 mph.If bentwheel lowers his WS by fourty (2116)his 60mph should be pretty close to dead on. You have to increase ur WS by twenty for every mph increase or lower it in Bentwheels case.

Try my 2054 or 2116 and see if that works for u.  U might have to tweak it, but check ur speedo at 60 and see how much the sigma is at.  good luck

BTW which one is the sigma reading and which is the speedo.  Is the sigma reading 20 while the stock speedo is 30mph?
