DSC Sport Controller Suspension Module

[Djseto]

My unit is arriving today. I'm looking forward to seeing how it compares to the DE5 module I currently have in my FL5. I won't be back at VIR until spring/summer (def will be a Type R meetup). I didn't see this video linked in this thread but I found this VERY useful. It's long but good for the people who want to DIY tune or at least understand fundamentally what it can do. Based on this video, the thing that is most interesting to me is the braking/anti-dive table.

At VIR, coming down the front (and back) straight pushing 130-140 mph , I am a very late and heavy braker. The weight transfer is so much that my rear comes up and moves around. @PointByPatrol even caught this on camera in one his videos. In theory, this should increase the front stiffness so I have less dive, less upset chassis, and better braking because I'll have the load spread across all 4 tires, allowing better grip and letting the rear brakes do more work as well. Being able to "electronically revalve" and adjust rebound/compression a shock is interesting but i think requires a ton of trial and error and is more art than science.

This looks perfect for my use (street, very occasional HPDE).

Just thought I'd share a similar thread going in the Integra forums for this same DSC Sport controller, as there seems to be more activity going on there. Hoping to get more input on these maps and fully unlocking the potential for these cars just on the stock dampers.

Got my DSC installed and did some driving today. I previously had the DE5 controller. Initial impressions:

• Biggest difference is in comfort mode. It's more compliant over bumps without being too soft in corners. I just spent 30 min driving my usual roads in my individual settings but with comfort instead of sport and I really liked it. Went over some train tracks and it's def. noticeable there. I could probably use it as my every day settings. If the FL5 Module was a setting of 3, the DE5 is a setting of 2, and the DSC is setting of 1 (or maybe even .5) if I had to put it on scale.
• Sport mode was a litte bumpier than the DE5. I could feel more imperfections and bumps in the road. I didn't spend a ton of time in this mode, but when I switched over to it, I found myself going back to comfort. I couldn't really push it but for this to be a setting I use, I'd have to tweak it in software to be a tad softer/compliant. Could also just be cause I was used to the DE5 and didn't have any real issues with it as my every day driving mode. On a scale, if the DE5 was a 3, DSC is probably a 3.75-4.
• Type R mode seemed similar to the DE5 in that it was usuable on the street compared to the FL5. I only use Type R on the track so I won't have a judgement on it until track season opens back up but I know the turns at VIR where I want my suspension to react differently.
• For all settings I found the front didn't dive as much under hard breaking. Cant wait to try this at VIR because I brake deep and hard and I can get the rear to lift and get squirely on the front strait into turn 1.

Overall, my first impression is very positive.

I just skimmed this. Def more people active but also looks like some of revisions are people running non stock springs. I see that Maya from DSC is active over there. I pointed her via email to this thread. Would be great if DSC was involved in this forum too. I even invited DSC to join our Type R track day. They could get a ton of tuning data since a few of us going have a 1000+ miles there under our belt.

I've read that the CTR uses a more sophisticated "adaptive" suspension range in the individual modes ie, if driven harder in comfort it actual adapts within the comfort setting. Have you noticed a change in damping depending on cornering speeds in comfort?

I'm curious whether you were able to notice the roll and push characteristics in Sport setting?

Thanks for sharing!

Not sure where you read this, but as far as I've seen, Individual simply lets you define a combination of settings, but isn't doing anything more than that. Given the Icepocalypse in my area, I won't be driving the car in the next 3-4 days.

That being said, if you watch the video I linked in an earlier post, the DSC allows you to configure suspension settings based on the detected Gs. The OEM does the same but with different settings based on this article: https://www.motor1.com/features/711587/type-r-engineering-deep-dive/

In my opinion, the DSC lets you tune it but I don't think it's adding more functionality than what was already there.

I'm trapped in the same weather storm (TN), so CTR is tucked away for the next 5-7 days.

I received my DSC last month and haven't had a chance to install and test it. I drove one installed in a Porsche 911 and it made a huge difference in the overall car. I tested one on my Focus RS and felt the standard off the shelf programing was overly soft and pushy in the normal suspension mode....ok in the sport suspension mode....but really took the "sharp edges" off of potholes. I wasnt into software tuning at the time so reverted to traditional mechanical suspension upgrades.

The reason for my question was that I saw a DSC video where they discuss the difference btwn factory and DSC capabilities. Their example was that if the range of damping capability for the strut was 1 to 10 (soft to hard) Honda limited their Comfort usable damping range from 1 to 3, Sport from 3 to 6 and R from 7 to 10. But DSC would allow the Comfort range to extend into the Sport range depending on how aggressive it was driven in the Comfort mode.

I've also read that some people claimed that the factory suspension setup in Comfort setting did the samething...getting much stiffer the faster it is drive .

My CTR was a very recent purchase so I'm still in the process of break-in and getting familiar with its capabilities...including suspension setup.

If I can restate your initial observations they seemed to indicate the following when compared to the DE5 module:

DSC Comfort mode rode better than DE5 module and damped the rough edges on impacts. (More streetable than CTR Comfort), DSC Sport mode was stiffer than DE5 Sport mode (assume slightly softer than CTR Sport) based on limited testing. You indicated that you hadn't really done much in DSC R mode but your early thoughts in was similar to CTR R.

If this is in the ball park then it would seem to be set up as a more well-rounded setup btwn the options for street use, but with a track capable R mode....perfect!

Type R mode is closer to DE5 than FL5. The FL5 would rattle your teeth out. The DSC doesn’t do that nor does the DE5 module. I really need to drive the car at limit to test Type R. This not the season or place to do it.

Summer down here in Oz (and 45 degrees Celcius tomorrow...113F!). I've been in the R this week and yes it's very marginally "floaty" in comfort but when you're commuting in traffic who cares! As soon as I'm on an empty back road I'm into sport or +R and its great. Waiting for Autumn before I track it. Too hot right now!

To me the DSC is a jailbroken ADS module preloaded with 3 different mapped settings.

For the new FL5 owner. Welcome. I’d suggest driving the FL5 a bit longer before installing the DSC so you can get to experience the difference.

Exactly, going to get a few 1000 mi on before dropping in DSC and engine tune. Overall, really impressed with the drive train and suspension from Honda, looking to selectively enhance the car with tweaks that suit my driving style and enviornment......aggressive street/ mountain and rural backroads (heaven for driving - 30 min from Tail of the Dragon).

Can you only purchase the DSC from them directly, if not, who has the best deal? Thanks

DSC only sells direct in North America. Just go to their site. They rarely do any discounting, but the usual Memorial Day , July 4th, Thanksgiving and Christmas holidays are psossible from time to time.

I believe these are still available at $995 vs their $1395 std pricing.

 

[JBO]

I got it at the presale price which is fair. Grab one before the price goes up.
