Sad to say my old Supercharged Phazer blew up. That being said it left Colorado with the GEMS set for 10k altitude and it went to New York.....I can pretty well guess what happened.
If you have a Supercharged Yamaha DO NOT run it if you have not became familiar in how to set the GEMS for altitude.
BOX #2 (6 wires)
1. This control box only controls the altitude compensation.
2. There are 2 Software versions for this Control Box. The early version has 5 modes, the later version
only has 1 Mode. Both versions of software function identically.
3. Older Version with 5 Modes:
a. Mode 1: Green, Mode 2: Yellow and Mode 3: Red have no impact on this control box!
Leave these set at 1 fast blinking.
b. Mode 4 & 5: Green/Blue and Yellow/Blue– These MUST ALWAYS BE SET TO THE
SAME NUMBER. CAREFUL, if you set this too low you may not be able to restart your
snowmobile. If this happens, turn your key and kill switch on, and readjust the setting back
up.
4. Newer Version with 1 Mode:
a. Mode 1: Green/Blue CAREFUL, if you set this too low you may not be able to restart your
snowmobile. If this happens, turn your key and kill switch on, and readjust the setting back
up.
5. Basic Altitude Compensation is Set at 5.0. At 6000 feet try 4, at 10,000 less (like 3), At Sea Level try
more, like 6.
Notes:
1. Radical changes in the controllers’ settings CAN CAUSE SERIOUS DAMAGE TO YOUR
SNOWMOBILE. If the sled does not act correctly and anything seems out of the ordinary compared
to your unit when it was stock (other than it now hauls ***). STOP and seek advice. Advise is free
and motors are expensive
