woot! i just got my sgII yesterday!!
 

its pretty cool & very easy to set up

i got one question, since i don't have the little manual with me

when i let off the gas in gear, it goes to 9999mpg, thats the fuel turning off right?
cuz when i stick it in neutral while coasting, it reads from 160-190mpg

i think i already know the answer, but i just wanted to verify it

You're right about the fuel cut. Congratulations on the purchase!
