Does Quaife change Gear Ratios?

Hey Steve i'm edging closer to the quaife.
BTW guys the mkd diff is like 4900 euros! wow i didn't remember it being this much.
Question, why would changing the ring/pinion affect the TC or ECU?
Since this is after the transmission,
Any change in differential ratio will set a gear ratio error code, placing the transmission in limp mode. The only way to correct, coding TCM and ECM with the new ratio.

Differentials DO NOT change gear ratios, only a ring and pinion swap will do that. Keep in mind that a very small change, ie 10%, will really NOT be noticed. A gear swap, say from 3:55 to 3:73, will really show little difference.
You need to jump at least 0.50 of a gear ratio to notice a real world change. That being said, you really CAN'T do it with a simple tire change. You will need to drop the overall diameter more than 2" do accomplish this. At that point the car would be dragging on the ground, okay, almost dragging.
See yeah

$2877 installed +$26 gear oil. Drives BEAUTIFUL. Right turns feels like I'm in a Go-Kart. Pulling out of driveways quickly to merge into traffic no longer causes ESP lights and engine cut-off. BEST MOD of all with PSS9s running a close 2nd place.
