"I suggest first to look for the part number of the the stock controller, who knows, maybe it might be same part number as Hellcat?"

Yes, I do think it is a hint as to see if the TH and HC cars use the same OEM suspension controller part number from the factory.

Kind of a backwards hint though as even if the OEM controllers had the same software for TH and HC doesn't automatically mean the aftermarket DS and DSC controllers have the same software tuning. But we know that answer already. 馃槒

I have been thinking about this, I am no engineer but I like to take a logic a approach to problems. I really like the way DCS sets up their controller compared to DS. I understand though the hellcats have 4 level sensors? And I think the TH has 3, I will be looking later this evening at my TH to confirm.

Why would there be different profile files if they all depend on the sensors of the vehicle? Also why have different profiles if they are tunable to each owns preference? Why does the mass of the vehicle matter if the controller is reading the G鈥檚, inclination, speed and whatever else it is reading? I mean creating a general graph where the suspension must be according to the sensor readings, kind of like engine map tuning.

The most limiting factor will be our tires for all cases of acceleration, lateral G鈥檚 and braking. The most that can happen is the controller can out perform the level of grip or create a super harsh ride to keep the TH level. But, again we can program the level of intervention.

Launch Control: a theory
I鈥檓 aware that the majority on this subject are not interested in going to the track, but for the couple of us that are, here鈥檚 my thoughts.

In looking at the Launch table (provided by Speedracer333) there is TPS Rate and it is set at 25. I am 鈥渁ssuming鈥 that represents 25%. (on page 2)

When using the Launch Control button, our Hawks are at 100% TPS when 鈥渦p on the 2 step鈥. Hence, when launched the DS controller will do it鈥檚 launch control thing. See pic number 1

When launched from the foot brake, I do not believe we are anywhere near 25% TPS, and therefore the DS controller does NOT do it鈥檚 launch control thing. See pic # 2 (pic鈥檚 were done using performance pages on the street)

鈥淚f鈥 my assumptions are correct then for a good dig, Launch control must be enabled - OR 鈥 one needs to go into the software and lower the TPS Rate. I鈥檓 not sure to 鈥渨hat鈥 but a scan tool should be able to tell what TPS is at 1500 rpm or wherever you prefer to launch at.
All the above is conjecture on my part due to the BIG differences (60 foot) between Launch Control shown on pic 1, and foot brake on pic 2. Same day, same temp., same section of roadway, minutes apart, using the Diablo Sport controller.

Lowered suspension should not affect the performance of a suspension controller as the TrackHawk does not have ride height sensors at all 4 corners. It will just run the shocks in a more compressed operating range of the shocks available travel but not affect the shocks damping so you should be fine.

What I don't know is if Swift springs are a linear or progressive rate set of springs. That will have more effect on the ride quality than anything.

Did you order a Diablosport or DSC suspention controller?

Diablosport - I'll be throwing it in sat. Reviews to come

That has been a problem a can鈥檛 get my head wrapped around. How well does the suspension controller work actively without sensors on every corner? If the controller works better with 4 sensors, how are the senors wired? Are they directly to the control unit or communicate through other controllers on the hellcat? If they go directly to the suspension controller than it might be wise to install the extra sensors to get the best out of the controller.

Hey Rolly, this work stuff is really getting in the way of playing with my hawk!
Nice testing! So you got your module back and all is good I see? What did they say about the lock-ups?

So what DS told me was that the "suspension" launch works with the Launch Control. They said the other way to enable it is to give the throttle a hard stab or blip (which should easily reach the 25% trigger). So if you prefer foot-braking it, hold the brake then give the throttle a quick stab.

I'm still confused on if the cars have the level sensors or not? It sounds like the Demon has it based on their claim that they are adjusting rebound and compression individually for the factory launch control feature.

The only thing our controller can do is react based on g-force sensors and firm-up compression and rebound combined. It would be cool to be able to customize the launch with separate rebound/compression settings. Then there is also shock velocity tuning based on the travel sensors, like rough roads/rail-road track crossings, and such... But we still only have 3 modes on our shocks and street is as soft as its gonna get.

Custom settings and performance pages are back! MY only complaint is that I would prefer all suspension settings to be as firmer under 40 mph (worse than with oem module) vs over 40 mph. Is there a way to do this with their software application? Should I send it back to DS for a revision? Remember I'm riding on Swift springs. Thanks

I found that in the SPEED table, under Speed G-limit Threshold (street mode) - if you lower the 0.30 for all 4 corners (f/r/l/r) down to 0.25, it will firm things up at ALL speeds, including under 60 mph. Found it too harsh for my tastes. If you wanted Sport and Track the same way, you would have to go to their table and do the same change. Try it in Street mode first to see if it meets your needs.

All I need to do is plug in the usb from the module to computer to this? Thanks
