I'm not really sure what you're asking, but the above is all I got. It represents changes made to the original 718 GT4 file (from 09-02-2020) found on the DSC Sport website. Start with that, then slowly make all the changes written out above.

Good luck!

I really really really wish there was a feature to compare maps in DSC Sport: it would make map review and tuning so much easier...... I tried a few different software to compare to no avail.

Here's the file with what colnagoG60 and mgordon18 have discussed based on their tweaking: this is the 718 file from DSC Sport repository modified as discussed in post #146

colnagoG60

When making changes from the stock file, its recommended to save the changes under a new file name (e.g. "settings.v2", "settings.v3", etc). As far as comparing, you could just open a 2nd instance of the tuning software, and open the respective files:

For those who want to learn more about tuning settings, and using the software, DSC has turorial videos available...this one being a little more informative:

Luca Paindelli

Yes, that's what I've been doing, but it's not as straight forward as you need to find the difference. What would be helpful is to export the numerical settings in a TXT format and then use something like notepad++ to do a an automatic side by side comparison that highlights the differences... Otherwise when comparing say two maps like the 981 and the 781 you'll have to go thought all the individuals settings and compare each individual one which is quite time consuming...

colnagoG60

Fair enough. For those new to the settings, most changes are going to happen on the "GForce", "Shock Calibration", and "Velocity" tabs.

"GForce": I'd focus on the values in the "G Comfort Parameters" section

"Shock Calibration": Focus on the starting and ending values of the Front and rear...software will automatically fill in 1-99%. You will only need to enter the starting and ending values at 0% and 100%.

"Velocity": Here you will need to check the values in the shaded area for Comp and Rebound, for the "front and rear", but "Left and Right" are going to be the same. Historically, the "Travel Stops" section has always been "0s".

DR.S

What I mean is to post ALL the values of the three main tables (like in #122) for both modes.
I guess this is one step before what Luca is intending.
From my POV this would be more convenient to compare differences ...

Larry Cable

@DR.S you are aware that there are two suspension modes, "normal" and "sport" selected by the console button with the "shock damper" logo on the center console.

Each mode has a separate calibration or map, containing the same variables, but with differing values (contained in a single physical .ptds file).

When you are using the DSC app to modify a calibration file you can select which map to work with, "normal" (yellow background in app) or "sport" (red background in app), typically/conventionally
the "normal" map is configured with values that optimize for "comfort" and "sport" is optimized for handling.

DR.S

Thanks Larry, I know this all

As Luca mentioned, a tool which compares all values "at one time", would be very nice...

BTW, what is 9x1 with LNC ?

Luca Paindelli

The LNC stands for "lunch control": this is a lunch control setting of the SUSPENSION, NOT THE CAR

It temporarily changes the setup of the shock to provide for better grip upon take off. You find it in the "Accel" tab with "Lunch start" and "Lunch end"

Larry Cable

Sorry I misunderstood your question; you wanted to know the differences in the values between the maps themselves...

DR.S

YESSS

I looked yesterday once again in the maps and the differences between the modes are still not logic to me...
It would bring light into the dark, if there would be a "stock" map, i.e. a map with values like in the OEM controller.

Thanks Luca, I guess I would have understood "LC" as launch control...

TDT

Lol, you’re going to have to take the time to build that tool yourself.
I extracted the values from my maps from my DSC to excel, and plotted graphs so that I could visualise the rate of change in damping, when making changes to my maps.
Ref OEM controller values, question has been asked before, DSC/TPC will not disclose, which is fair enough.

DR.S

TDT, feel free to share your Excel

For which reason should it be a secret to show the OEM values...

colnagoG60

OK, so I think I'm finally done...at least addressing all "my" issues/needs/wants. Anything different "for me" at this point is just splitting hairs, or slight changes in Shock Calibration (+- 100 at the soft end) to adjust for tire pressures/seasonal changes.

My last main change was in the "Default Rate" in the G-Comfort settings...lowered the stock file value to (10) and it removed that last bit of low speed abrasiveness I was getting in the rear. Car now has reduced accordion/gummy feel I was most recently getting (may or may not be a good thing in keeping tires on the road, but I feel more confident), and now has that firm/taught feel I was going for from the start. Mostly glad I got rid of the cabin jostling I didn't like from stock PASM. I'll probably drive in Sport 99% of the time and would switch to Normal on only "ongoing road construction bad" type roads.

Here are the changes, with my all-seasons at 33lbsF/36lbsR after 20 min ride to dealer on highway, with air at 54F (..and even though firm, still think it could handle some stiffer springs...YMMV):
