DSC Suspension Controller - tuning and talk

[rayzazoo]

What settings did you need to change?

Looks like a progressive front suspension rebound control.

Great summary @rayzazoo. I really CAN feel the independent shock control just driving down the street. That is one of its big differences that I have enjoyed.

The one item that looks interesting is the comfort numbers, and the most easy to change. Less is softer as the default or at no input from driver. Sport rides more soft than street! I am going to drive it a bit today and see if I can feel the ride difference btw Street and Sport. I’ll start there.

Let’s hear more about the acceleration deal. Ray says 1500ms, I may just change it and see if I can perceive something there too. It can accelerate if I want it to.

I think it'll be dependent on the setup. Once you hit 60mph or the threshold timer, the acceleration table is done.

So let's say est. 0-60mph - threshold timer = time not in accel table
Hellcat 3.7 s - 1.5 s = 2.2
Redeye 3.4 s - 1.5 s = 1.9
SS 3.25 s - 1.5 s = 1.75

Diablosport only spent 1 second in the accel table while DSC had 2 seconds. When Mike from DSC was made aware of the DS controller, the feedback was 1.5 seconds might be the sweet spot, but that was also for a 2015 Hellcat. Once the timer is done, it goes back to the GForce table and %.

Another thing to consider is actual 60ft times. If these are <2 seconds, then it helps explain why DiabloSport elected for only 1 second vs DSC 2 seconds.

I think a more accurate measurement is log personal 0-60 ft times. Then tweak the threshold timer.

Next, tweak the acceleration table % on the the desired amount of front soft rebound and firm rear.

This would match how the Demon is getting their launch suspension strategy: "Bilstein adaptive dampers are set to firm up compression and rebound in the rear while softening front rebound, letting the front end rise freely as weight shifts entirely to the back wheels "

So firm rear shown by 10% rear and soft front shown by 100%.
