2015 mustang gt auto gear change ?

[jrs01]

Leaving stock tune just to see the difference between gears
But in the tune there are three ratios to change
Ratio 3.15 to 3.73
Max ratio 3.57 to ???
Min ratio 3.13 to ???

What to change min and max

[rkrebs27]

change the max number to something like 4.13 I believe.

Flip the switch, set the ratio, and adjust the min max if the value is outside the range.

[jrs01]

Do you mean enable final ratio

[Eric@HPTuners]

Yes

Just wondering if this works or not. Had a friend say his tuner and Kelly at BMR both say the switch does not work. They say the gear ratio is held in the BCM and not the ECM?

this is supposed to take the BCM out of the equation and as far as I can tell, it works on my car.

Flipping that switch is what tells the car to use whats in the ECM vs whats in the BCM. on the 11-14 coyotes the switch refers to whether you want to use the VID block, or whats in the tune;

i have recently tuned one, and i did not adjust the switch only ration and set min and max which is just above and just below actual gear ratio
