Speedometer Calibration...
Hello All,[sm=helpout.gif]
Wondering how would you go about calibrating speedo....................I have read where you can change setting on a tuner for gear change...........I am changing to 373's and going to a 255/45/18...........what would be the method of calibrating your speedo.......I went to a shop that calibrates speedo's and he said upward around $550.00....................I think this guy was smokin something.................anyway any knowledge would be appreciated!!!
Have a nice Holiday and hopewives and girlfriends pop for mods on the wonderful day!!!!
Cheers!
Eddie

RE: Speedometer Calibration...
Hello gents. I thought I knew the answer but maybe I am wrong. I thought that all you had to dowas find out the diference between standard calibration of rear gear to tireO.D.ratio and your customized rear gear to tire O.D.ratio. This allows you to find the difference in drive line rotaions, per every one turn of the rear tires, and the distance achieved by the rear tires, per rotation. Once you have the twonumerical values of the rotations per distance of the rear tires to driveline rotaion.You can properly change the vehicle speed sensor gear to adjust for the difference, it would make cpu reprograming unnecessary. If I remember correctly a new speedo gear runs about 12 dollars and takes a 3/8 ths wrench to change. If I am right it would only take a simple calculation and cost 12 dollars fora gear. If this doesn't make sense or I am totally wrong let me know.
