Question on edge evolution
trying to program the gear ratio and tire size on my 06 f150 4wd with 37x13.50 tires and 22x12 wheels so i can get my speedo back on track as well as my shift points.
on my edge it has the stock gearing on there which is 3.73.
Wouldnt i need to input my final drive ratio that the tires decreased the gearing down to, into the programmer? i used a calculator and it says since ive added the tires my effective gear ratio is now 3.23. should i input 3.23 for my gear ratio, and then input the 37" tire size into the programmer?
i have tried leaving the 3.73 on there and input my 37" circumference for the tire, which i was guessing was the correct way to do it and the speedo is off by like 10mph compared to my gps. can someone enlighten me here?
