Tune Question

[Uncle Buck]

Is setting axle ratio part of a custom tune?

If it is and I don't have the tune file updated, can I simply overwrite it manually with my SCT X3

I don't know if it's axle ratio but there is a revolutions per mile setting, as long as your tune file is unlocked you should be able change it. I've played around with compensating for my eyes streets which are 26 vs 27"
Or if you still use Lito he can change for you

Been a while since I did this but if the tune allows for that to be modified (which it should) you can change it from your handheld.

Go to program vehicle, select the tune you have been using, then select "adjust options", scroll down to axle ratio, enter your new gear ratio. Rev's per mile is to adjust tire size, my SCT has a separate option for axle ratio.
