Tip: You can increase your controller's diagonal sensitivity range

As a quick preface, for those who didn't know, awhile back it was discovered that the DualShock 3, of all controllers, has a different driver configuration that gives it more diagonal range in the analogs. To explain this, imagine the full range of the analog represented by a square. With other controllers, the analog stick range is represented by a circle within the square, so when you push the stick to diagonal extremes, it "doesn't reach" the corners of the square. With the DS3, diagonal movement does reach the corners of the square so you get a little bit more range in those directions. This allows you to execute faster diagonal air rolls and other diagonal movements.
Basically, tl;dr the DS3 utilizes the full range of analog movement whereas other controllers don't. There used to be workarounds for this using tools like Durazno's, but somewhat recently Steam added controller configuration support for non-Steam Controllers that also has this functionality so we don't need Durazno's anymore! Here's how to do it:
(As a quick note, I am personally on Steam beta but I don't know whether that is necessary to utilize controller configurations. If you
don't see some of these options described below, try opting into the Steam beta)

Here's how to do it:

• Plug your controller in. Go to Steam settings and click on the Controller tab that should be at the bottom of the list.

• Click the first button here, which should be General Controller Configuration or something like that.

• This should open up a Big Picture window with some settings. Enable the checkbox for your type of controller (it should say something like "Enable Xbox Controller Configuration" or whatever is appropriate for your controller).

• Close this window and go to Rocket League in Steam. On the right-hand side, there should be an button labeled "Controller Configuration" (you can probably also get this option if you right-click the game). Click on that.

• This should open up another Big Picture window, this time displaying all of your control mappings for your controller. Go to the box that represents the left analog stick and click it (should be the left-most box on the bottom).

• Go to Advanced Settings in the bottom right.

• In the left column, there should be a setting labeled "Deadzone Shape" or something like that. It should be set to "Cross" by default. Click on that and from the drop-down menu select "Square."

• Close out of the window and enjoy your new and improved range of motion on the left analog! This should make diagonal air rolls and all diagonal movement noticeably faster.

• Please read the edit at the end of this post to learn how to turn off Big Picture Overlay!

NOTE: If you're skeptical of whether this actually works, it's actually very easy to test. Repeat the same steps above except instead of selecting "Square," select "Circle" for your deadzone shape. This will set your stick's range of motion to the default circle that I was talking about before. Now go in Free Play, and with your car sitting still, hold down a diagonal direction. Keep that stick held down and then push and hold jump. Try this a couple times and notice how your car lands and how many times it rotates. Now go back into the Controller Configuration and change deadzone shape to Square. Do the same thing in Free Play. Your car should land differently and rotate faster and more now when you do the diagonal flip.
NOTE 2: To be clear, it is a bit strange that the "deadzone shape" in Steam controller configs also affects the overall sensitivity range and shape. What we are trying to change here is not actually the deadzone but the range. But oh well, it works so I won't complain.
Hope this was helpful.

Solutions to common problems:

• I can't open Steam overlay without it being a weird Big Picture controller thing, what do I do?!

-Go to Steam settings.
-Click on In-Game tab.
-Uncheck "Use Big Picture Overlay with Steam Controller."

• This isn't working with my DS4!

People have reported problems using this with DS4. I hear that you can use http://ds4windows.com/ as a custom driver to make your computer recognize it as an Xbox controller.

• It screwed up my rumble!

Open Steam in Big Picture mode, go to Rocket League > Manage Game > Controller Options > turn Steam Controller Rumble Emulation OFF and enjoy!

• It increased my deadzone!

Open Controller Configuration for Rocket League, go to your left analog, Additional Settings, go to Output Anti-Deadzone and increase it to the very first notch instead of 0. For some reason, without an Anti-Deadzone Steam will add extra deadzone to your in-game setting in Rocket League. Weird!

Is this the kind of tweak that would improve driving performance, as in get my car to turn more sharply in game? Here's my issue, that I've just started researching for a fix...

I'm playing a racing game and I've a vehicle that understeers (swings wide). I'm wondering if there's a way to increase the range of motion on the stick of my controller that would... could... might ... deliver more input/signal to the car's steering and get me through some sharper turns. If that's even possible! Thanks!

Any other suggestions would be appreciated cuz nope, I'm not gonna switch cars. lol

Hey there! The option for the dead zone is in "additional settings" now instead of advanced settings. Not sure if or when this was changed. But if you can edit that for future people checking this out, that would be great. :)
