Purchased a 2006 supercharged L322 with 24 inch rims already on her. I am going back to 20 Inch stock rims. Do I need to reset/change anything? Battery disconnect perhaps? Or will the car automatically recalibrate itself? Please help...

No, it has no way of knowing what size wheels are on it. Measure the rolling circumference of the 2 wheel/tire combos with a tape measure. If they did the 24’s right, they should have very close to the same rolling circumferences. The smaller wheels should have fatter tires...the larger wheels thinner tires, so the net rolling sizes are roughly the same. If they are way off, I bet they never calibrated anything for the odd wheels anyway.

Thanks for info. The difference is almost two inches, give or take. Going from 295/35/24 to 275/40/20.

275/40/20 are not stock tires for the 20 inch rims on a L322. They should be 255/50/20 for the standard factory rims. So the difference will not be as much but still a fair amount. (275/40/20 are stock for the Range Rover Sport)
