This video explains it all: Diablosport suspension controllerRayzazoo,
Thanks for the post and for digging into the numbers.
This sounds like we're getting somewhere - listing distinctions in OEM settings for starters.
Do the DSC/DiabloSport controllers similarly ramp up base starting firmness for the three selectable modes? Is that all it does, or is there additional tuning for anticipated standing start launches and braking forces?
One consistent observation is that when braking the controller senses weight transfer towards the front and firms up the front shocks. That has to be a matter of enabling the controller to sense longitudinal G forces and if it can do that then programming it to do the opposite - allow more rear shock compression and perhaps more front shock extension too - during hard launches or rolling launches - would be a great way to get more wheel downforce on the rear wheels to help avoid spinning the tires.
For initially turning, is there a customized for the Challenger's weight, springs and shocks (predicted body roll), change in individual wheel shock firmness?
It sounds like, since you used Track as your straight ahead example, that the DSC controller in Track mode would be in firmest base ride 100mA in all four corners (like OEM), then sense a bump in one wheel so quickly it could go into OEM Street mode's 400mA softer ride response to absorb the bump and keep the wheel in ground contact, then quickly go back into 100mA in all four corners past the bump. Is this correct? If so, this is a big improvement over OEM Track mode.
But, if the above IS true for Track, and perhaps Sport mode as well with its base 200mA setting, why would anyone ever want to drive in anything other than Track suspension mode? You are essentially saying the controller can sense bumps so well that it will automatically briefly shift into softer ride modes for those wheels affected by road imperfections? If that is true wouldn't the ride over suddenly bumpy roads simply feel like Street?
It also sounds like, again using Track for your turning example, that the DSC/DiabloSport controller in Track mode would be in firmest base ride 100mA in all four corners, then as the turn is entered sense a difference in G forces between the inner and outer wheels (primarily more downforce on the outer wheels, less downforce on the inner wheels as the body weight rolls towards the outside of the turn) and go into Street mode settings of 400mA for the inner wheels, then go back into 100mA in all four corners as the car straightens out. Is this correct? If so, is the controller's switching to the softer inner wheel shock setting allowing greater inner wheel shock extension, and perhaps doing it quicker, than the 100mA Track setting would allow for? If so, it would keep more inner wheel downforce (and tire rubber downforce) on the ground. More inner wheel friction on the ground in a turn would improve handling (and safety) - maybe by a lot.
What happens if you start out in Street going straight and hit a bump or depression in the road? Does the controller go even softer than 400mA? If not, what would be the benefit of ever being in other than Track? If indeed Track handles sudden bumps like the two lesser firmness modes? There would seem to be no advantage, or reason, to not being in Track.
What happens if you start out in Street and start a turn? Does the controller change the outer wheels to Track settings - to 100mA - while keeping Street's 400mA on the inner wheels? If so that would be pretty great - better handling avoiding Uncle Jed's refrigerator or just carving turns always equals better safety - and it is more fun. But again, why ever select Street or Sport suspension mode if all the above is actually true? Or even mostly true?
I hope it is true. Replacing the three OEM selectable suspension modes into one super can-handle-all-ride-conditions individual wheel sensing and shock response Track mode sounds fantastic to me. Base handling in turns like Track, straight ahead ride like Street, sensing longitudinal weight shifts for better friction starts and less front end droop stops. Sign me up.
If you, or anyone else on the forum, can answer these questions we'll really be getting somewhere in understanding how this works.
You will need to datalog the individual sensors to gauge where/when you want to make changes.
DSC likely dyno'd the shocks, made a preliminary baseline tune, and fine tuned the controller in a car. Tuning a car to individual driving styles is very subjective. This is a 90% solution for 99% of buyers out of the box.
At best folks can sharpen up the response times sooner or delay them for more weight transfer relative to the G's seen. Assuming they have the tools and knowledge to know how. But, most people who venture into tuning this will probably end up ruining things or seeing little return or end up claiming a false positive/placebo effect.
You are over thinking this and over complicating it and muddying the waters. This box takes a linear system and makes it parabolic.
