Interesting. I find it to be very underdamped in all three modes on a stock 2014. The amount of rebound motion over medium to large bumps is quite disconcerting to me.

It seems very biased toward a cushy ride. Even in R mode the rear moves way too much compared to stock over bumps. It feels nice on a flat road but undulating pavement upsets the car too much.

I played with the software and think it will take a lot of trial and error to dial in the suspension the way I want it given the number of parameters that can be adjusted. The software seems oriented toward a race team crew chief and not so much toward a hobbiest / enthusiast. I’ve tuned my suspension on several cars for street and track and have learned from books and suspension tuners so not a nube.

Kinda disappointed...

I'm sure you can return the pcb and get your money back. I ran Big Willow last month with the oem suspension computer, and I'm running it again in a couple weeks with the DSC suspension computer, so I'll be able to better compare apples to apples over the same terrain. From a layman's perspective, simply driving the car around town is nicer and more pleasant with the DSC comfort program verses the OEM comfort program. I bought the car to serve two purposes: fun to drive around town, yet capable of track duty at a recreational level. Hard to make a car that's all things to all people, and particularly hard to make a car both comfortable and a fully weaponized track monster. The reality is that most cars see mostly street and little (if any) track. I drive 175 miles to get to the track, do 50 laps, then 175 miles home. The idea of having a car that can be soft(ish) around town and tight at the push of a button is very attractive. Nissan did an okay job and I think the guys at DSC bettered it, and the beauty of it is if it's not to your liking, you can tweak it via trial and error which is how all suspensions get modified.

To those who have tuned their DSC controller's. what is the step by step tuning procedure? Where do you start and what is the most important stuff to adjust?

The first thing is to set the range of current on the Shock Calibration tab. This range affects all of the other tables within a given map, so if you just want R mode to be stiffer across the board, go to Shock Calibration and lower the mA values throughout the table.

The next thing is adjusting the G table. I’m still playing around with that, and I had a good head start from my tuner. He didn’t like the settings they ship with, it took awhile to customize it and come up with a good map for the GT-R.

If you have specific questions just PM me.

The controller is not refundable. But, they said they’ll replace the broken faceplate under warranty; nice.

We are also discussing whether or not the controller is able to address the undulating pavement without sacrificing comfort too much.

I’ll report back after I have more info.

Installed on MY17.

Thanks to all that advised on how much of a pain it is to install. Switching boards was the best advise. Practiced on the DSC unit then did the same for the stock unit in place. Probably took about 20 minutes or less to do.

Observations:
Comfort is not any more soft. Still have that wobble feeling from the MP4S 345 tires on the freeway transitions. Was hoping this would get rid of it.
Switch remembers last setting.
R mode does not trigger exhaust to open like stock.
Takes longer to flip between settings. Any way to change it to react the same as stock?
R seems to feel more planted during spirited driving.

It’s only been 2 weeks. All street driving.

Is Comfort at least as comfortable as stock?  My concern is losing the Comfort mode on my '15.

Yes, comfort feels the same. From what I read, MY17+ are the softest. So you may experience an even softer feel.

Side note. Just had my 2nd year POS done.

If taking your car to the dealership for service, the ECU will read an error that it cannot communicate with the suspension computer (DSC).

Tech was cool with that when he understood what was done.

It's more comfortable than stock. 

 

DSC Comfort is OEM comfort plus 20% softer.

DSC Normal is  OEM comfort

DSC Sport is OEM sport but more planted.

 

IMO, for what it's worth.

Just a heads’ up - if anyone would like help tuning the DSC or creating new maps from scratch please PM me. I’ve been working with mine for about a year and have done several custom maps that work very well at the racetrack.

Cheers,
Wes

Do you have a comfy street map that doesn’t float like a Cadillac?

My current comfort setting is still a track setting but for bumpy tracks haha. I should be pretty easy to come up with something that is soft when going straight at low G’s, but firms right up when cornering, braking, or accelerating.
