Calibration file is different to Firmware file....the Bilstein is a calibration file....
Firmware version used to be published on the website - but both this and the firmware uploader don't appear to be available for download any longer.

Ok. I guess I got the two mixed up in my head. Is there an easy way to check the calibration file?

I don't believe the controller saves settings as "files", as it only saves what is set for every parameter. Once you finish "Writing All", just be sure to click on "Reset Board", before disconnecting. You can always close the software, re-open it, and then do a "Read All" to see if changes from the new file are there.

For whatever reason it was in my head that it was firmware. In one of their videos it shows loading a pdst file and then checking the firmware right afterwards...derp on my part. Thanks for the help!

The software writes the values of the table to the controller - so there isn't a file stored on the controller as such.
Do you know what file you were running before?, do you have a copy of the file? if so you can open 2 instances of the configuration software... load the old file... then in the second instance... do a read from the DSC...
you can then compare max and min shock values - as this looks to be the primary change in the new Bilstein file.

I think the "Velocity" values changed (in Sport Mode) from the "Roll Center" settings...if not, FWIW, I'm now running the current "Bilstein" file, but changed Shock Calibration to:

1200-200 Front
1200-500 Rear

However I may be changing that to 1300-500 Rear, to give it a tad more comfort for casual driving...change makes it feel a little more "sporty" than the Normal mode, when switching between the two, at around town speeds, while still allowing for daily driving.

Still tweaking the "Bilstein" file. I like it overall, as it seemed to reduce some of the "extra bounces" after hitting a single bump, but felt like it was a tad "gummy" feeling. Also felt like the rear was lifting up more than the front when hitting a bump. Now using the following changes from stock "Bilstein":

Sport Mode:

Shock Calibration: Front 1200 - 300, Rear 1300 - 600

Velocity: Rear Compression H-M-L 5%-5%-0%

These settings make the car feel a little firmer than the stock file, and as if the struts are moving a little faster, all while still keeping the tires on the road. Changes from the "Normal" mode are not drastic, but enough to feel a difference "around town".

Ive been playing with the DSC velocity settings.just so i understand if i decrease the compression setting by -10.0% im softening the compression and softening the impact?
. If i increase the rebound by 10.0% the wheel will drop faster, and by decreasing it -10.0% will make the wheel drop more slowly?
I think that's correct ? Or do i have it backwards ?? Not fun getting old!!
please advise thanks carl

Minus on compression = softer on compression.

Plus on rebound = slower wheel drop, and slower rise.

4carl

So -10 on compression and +20 on rebound will slow down wheel movement? thanks carl

I believe TPC has mentioned that 10% is pushing the upper limit of the "Velocity" values for the OEM shocks.

I thought i read in a post from Tom that 25% was the limit? Maybe that was for MagRide? carl

colnagoG60

I stand corrected...Tom mentioned 25% level earlier in the thread. I may have been remembering/mis-remembering 10% on one of their videos. Apologies...been mired in Microsoft Virtual Host issues past few days.

I thought i had a fairly good understanding of suspension tuning. I had triple adjustable Nitrons on a lotus that i tracked for 7 years.
Did all my own set ups(still do) inc corner balance and alignments. But I do have to admit this can get confusing?
Basically from what i understand, when you increase or decrease velocity you are actually changing the dampening force in a specific situation.I.E High,med,low impacts
Increasing it makes the piston move slower(stiffer), decreasing it makes the piston the piston move faster (softer)...Correct?

Of the two calibration files on DSC's site, does anyone know if the non bilstein one is the same as the one prior to the 2-12-20 date listed? The Bilstein file does not work (for me) in autocross. The car feels floaty, twitchy, just not connected like it did before. I saved the file that was on my controller, but the hard drive it was on is no longer.
