[QUOTE="mwolson, post: 9526346, member: 16006"] That is the correct code for crash's setup, assuming he has an extended range speedcal and stock speedo gears. The best way to test it is to find a place where they have accurately marked out up to 5 miles. If you drive those miles at exactly 60 MPH on the speedo and time yourself, you should take exactly one minute per each mile. Where I grew up, they had a section road every mile so it was easy back there. You guys can all check my math because I posted it on the calculator pages below the calculators. For those of you who are into math, the speedcal switch setting is a 10 bit, fixed-point number with a 3.7 format. The first digit represents 4, the second 2, the third 1, the fourth 0.5, the 5th 0.25, the 6th 0.125, the 7th 0.0625, the 8th 0.03125, the 9th 0.015625 and the tenth 0.0078125. Just add up the numbers corresponding to the bits that are 1, and you have your multiplier. [/QUOTE]
