Electronic Stability Control

[Cpunlamd]

Hey guys. New to the forum. I’m a new owner of a Gen V 2013 BASE SRT. I have been searching for my next modification and landed in the DSC electronic stability control module that supposed to be a plug-n-play system. I uncovered my rear hatch to find the factory module absent. Harness is there, but the module is not. Is this something to worry about? My previous 2013 GTS was equipped with the module.

The base SRT doesn't have 2 mode shocks. The DSC unit is said to still work but if you want to have the ability to switch between two settings on the fly you'll need to get the panel/buttons in the interior. If you don't care about being able to switch like that I believe you can still plug everything in and it will work, just changing the settings will require a laptop.

Another point after I re-read your post. If you're referring to JUST the DSC module it won't work at all since your shocks are not 2 mode. That module is advertised to 'work' with the 2 mode shocks but in reality it doesn't do much at all. To get the real benefit of the DSC system you have to go with their $8k (or whatever) setup that includes shocks.

Thank you for your input. I didn’t know how stripped the BASe SRT was until I started digging into it. There were a lot more doodads involved on my previous 13 GTS. I like the DSC package, but their MSRP is inflated. I can get the factory ACR Bilstein, Moton, and JRZ suspension at that price range.

Echoing what Voice of Reason said:

1. You don't have the bi-mode suspension so it will not work and you don't have the dash panel with the buttons needed to control it.
2. It was concluded in this thread here https://driveviper.com/forums/thread...ory-OEM-shocks that the DSC controller wouldn't do much even if you have the GTS or TA bi-mode suspension, mainly because they are a simple system that uses a fluid reservoir and a valve that is only bi-mode which means either opened or closed. There is no evidence that the valve in the factory shocks can be manipulated to manage the fluid in the reservoir in different amounts or if it can even move fast enough to be adjusted at the rate advertised.

What is your goal? Is it improved ride quality or more adjustability for the track?

[Cpunlamd]

Best of all worlds I guess. I was under the impression that the DSC system would help the car drive better around town and would know when to get in attack mode when it was time. Apparently it is a smart system that would adjust real time.

In conjunction with their own coilovers, yes it's supposed to be that way within a given programmed mode. With the stock shocks, you'll see limited improvements as mentioned above by solely replacing the controller.

For a simple example:
The smart system it has only allows it to alter the damping within the programmed range, which can't exceed the range for the stock shocks, so it will never be overtly better. It may make subtle changes within that range, but can't work beyond it. So if street mode is set from a 0-3, it can actively dampen anywhere in a 0-3 range. Whereas race mode may be set for a 2-5, in which case it'll actively work between 2-5, but not 1 or 0 as they're outside the programmed range. If the stock shocks can only manage a 1-4 range, then the active system would only be able to operate at 1-3 on street, and 2-4 on track modes.

On top of that min/max capability our stock suspension is an open/closed valve system, meaning it's either running 1 or 4, nothing between and is a smart system - in that it monitors inputs (throttle %, brake %, speed, rpm, abs, esc, tc, etc). It will stiffen to 4 from 1 under certain conditions established by those inputs, then back. So all the new active module can do differently is monitor more frequently, have different thresholds on the input table, and add inputs from other sensors that the stock unit doesn't monitor [ie: g-force]. All this can do is alter the conditions dictating when and how frequently to change the suspension from 1 to 4 and back. This may smooth out some of the bumps it detects by stiffening to 4 and allowing a plush ride by dumping to 1 when 4 isn't needed, but doesn't effectively control the damping like what most think of as a "true" active system in between these factors.

The street/race mode button options allow 2 programs to be set in which the monitored inputs have different thresholds dictating moving between 1 and 4. So one can be set for a stricter set of parameters dictating change to 4, so it stays in 1 under more conditions allowing a softer ride. The other can have the parameters set much lower, dictating it changes to 4 under much lighter conditions, providing a stiffer ride.

The bang for your buck is up to you to determine if it's worth it, but the gain is isn't going to exceed a seat-of-the-pants only hp gain. No discerning differences that can be chalked up to much beyond placebo effect.
