With SimCommander (SC4), you can use the AutoTune feature to set a custom profile for each title and/or car & track combination. Or you can manually tune but, initially, try some AutoTune profiles to get you started until you are familiar with how things should feel.
The main point to remember is using the game-FFB output to regulate the force strength in order to avoid clipping (especially in AC). If / when you notice a lack of detail and springy feeling FFB during hard cornering, it's usually due to soft-clipping (game-FFB output). Try using 90-100% FFB Intensity in SC4 and set AC-FFB gain around 35-50% to insure there is no clipping occurring. (You can also use the SC4 clipping meter to monitor the actual signal output).
Be aware there are very simple ways to manually tune SC4 by reducing the number of effects you utilize initially. Switch most of the effects off and start by focusing on the basics; Force Intensity and Game-FFB is pretty much all you need to get started in SC4 (Enable Gyro in AC). The FFB is very likely to feel raw and grainy until you turn up the smoothing. If the wheel feels too loose around center, add a small amount of friction (a little goes a long way). The smoothing scale range is quite broad so it's not unusual to run that pretty high, especially in AC / ACC.
With the AccuForce set to Default Mode, you will generally get the best balance of detail and forces but, once you learn how to tune in SC4, you can try other modes. Foundation FFB is another way of producing FFB based on game-telemetry but, save that for later, after you are familiar with how the systems feels and you know what to expect. Some titles that work really great with Foundation-FFB are the Dirt series. I find it much easier to tune SC4-FFB than I do CodeMasters' settings; and imo, with better results.
Tuning can be fun and the best way to learn what each effect does is to experiment but, just make sure you are not running with high torque settings when doing so. You may want to read this guide before tuning manually:

There are other useful guides about AccuForce tuning as well and it's a good idea to learn as much as you can before the DD-system arrives so the settings don't overwhelm you. It can be pretty daunting when you first access all of the possible settings but, it doesn't have to be complex if you understand the basic fundamental settings to focus on. The rest are more about fine-tuning things.
