4.10's (Speed cal box)

[ALkYuLA]

Hey can anyone help me out--my speedo is still off after installing the Speed cal box. What RPM's are you guys with 4.10's turn at 70 mph with stock size 17's and the T-45? DM told me i need to check for a 19 tooth speedo gear or the box wont work. Thanks.

your rpm's at 70 would depend on what gear you are in

ALkYuLA, you dont need to change out the driven gear to get it to work. Driven at least 10 miles against another car and record both odometer readings to the tenth mile and your current switch settings. Email them to me and I can send you another set of codes to try.

I really need those switch settings for this method. I sent you PM reply with the same thing in it. Just pull the settings and PM me (or post here), leave the cover off, and I'll give you a reply this evening.
