Per my copy of the Owner Manual:
TracDSC is an alternative setting of DSC, with
reduced system interventions. With TracDSC
engaged, traction may be increased, although
stability may be reduced compared to normal
DSC. TracDSC is intended for use only on dry
tarmac, by suitably experienced drivers.
TracDSC should not be selected for other
surfaces or by drivers with insufficient skill and
training to operate the vehicle safely with the
TracDSC function engaged.
Press and hold the DSC switch for 1 second
and then release.
SWITCHING BETWEEN DSC AND
TRACDSC
Press and hold the DSC switch for less than 3
seconds. The Message centre will temporarily
display either TracDSC or DSC On.
The DSC Off warning lamp will illuminate when
TracDSC is active.
Note: Cruise control will automatically be
disengaged.
And:
Press and hold the DSC switch for more than
3 seconds.
• The Message centre will display DSC Off
and a short warning chime will sound.
• The DSC Off warning lamp in the Instrument
panel will illuminate. See 40, DYNAMIC
STABILITY CONTROL (DSC) (AMBER).
SWITCHING DSC ON
Press the DSC switch for 1 second and then
release.
The DSC system will switch on, the Message
centre will temporarily display DSC On.
Note: Switching the engine off and then on
again, will always revert DSC status to DSC On,
regardless of which mode is selected.
So if starting with the default setting of DSC On you press the DSC button for one second to get TracDSC and for three seconds to turn DSC off.

Hi, please is this a "limit" what cars can be flashed? Recently I read that TCU is limited only to non-flexray cars? Is this true and does this also apply for ECU? Can I somewhat spot what the car is equipped with?
Currently in a process buying a car and I want to get the tunes! Thanks

Well, Stuart did say "We can flash any model year of Supercharged V6 or V8." so that seems to answer your first question. Flexray seems to only affect the transmission flash.
#1326
Yes, I understand, but wondering to what degree (still up to 605 HP?) or if there are any other constraints or considerations based upon the baseline of lower spec'd engine...

No constraints, the engines are mechanically identical, the difference between 450 and 605 is purely in the tune.
#1328
Yes, they can be flashed, the power output is the same with any tune, or pulley combination. The P450 isn't lower spec, it's just de-tuned with software.

I guess it is not possible with VAP tune to "reverse" the dealers update that change the exhaust valve operation aka muted exhaust problem? I know VAP can reverse burbles but can it reverse the valve and cold start?
Or put more simply, can VAP make 2020 cars behave like OEM originals?

On the topic of the P450 and how far it is detuned, mine (a UK MY21 RWD model) was put on the rollers a couple of weeks ago and came out as just over 500hp and 510ft/lb of torque (calculated crank power, not at the wheels). The torque was absolutely flat, with a few wobbles, from 2400-4900rpm. Apparently it isn't all that unusual to see quite a bit over the official figures on these from the factory, so don't take the '450' figure as gospel.
I wish I'd got a copy of the run with the ATW figures, rather than the calculated crank numbers.

I don't even need you to hold my beer, I can do this with 1 hand. If you want the pre dealer pops update sound, that's easy..

And with pops, do you have the "original" OEM map for that, or yours that behave differently? Basically my goals is to have 2020 silenced car after K309 to sound like Jaguar wanted in the first place.
Thanks

Well the sound silencing from K309 update was not only pops, but also RPM limit in normal/dynamic modes to open valves and I think also cold start behavior. Is this reversible by you?

The K309 was ONLY to cut the delay of the fuel overrun in half, nothing more, nothing less..
There's many calibrations per JLR vehicles, take a F-Type 5.0, there's about 8 calibration worldwide per model year. Up until the K309 release, a simple 2016 F-Type 5.0 North American Spec already had GX53-14C204-BAC, GX53-14C204-BAD, GX53-14C204-BAE, and then K309 for that calibration was GX53-14C204-BAF.
Do I have all of those, Yes.
Was there a change to the RPM limit in normal/dynamic modes to open valves and cold start behavior?
Nope, not a single thing related to any of that..it's ONLY the amount of "time" for fuel on overrun and it was cut in half. For example, what was 2 seconds would become 1 second in K309 update.
Fyi, you cannot put a 2016 calibration that was pre K309 into your planned 2020MY. The main reason being, it's not even the same ecu type, it's a completely different ecu that is run on the flexray comms system. The mapping is also different for a 2020MY to a much older 2016MY. Yes, I can make them pop and bang just the same, but this would also require you doing work on your own end to disable the GPF hardware.

With GPF fitted, it just reduces noise or it will be destroyed with pops like before?

That change occurred at an earlier update (H28x?). On my MY18 pre-update the valves opened from tickover in dynamic mode and in non-dynamic if the exhaust switch was activated. After the update the "non-dynamic exhaust switch on" behaviour changed to only open from about 1500 rpm. Dynamic mode valve behaviour seems unchanged - valves open from tickover. 4k rpm is the "standard" valve opening for non-dynamic mode with exhaust switch off.

Thank you for your time to explain this to more detail. Yeah the amount of versions complicate things a bit. Do you thing there might be a region difference with this? People on UK forums (I am located in europe) swear that the new cars open exhaust valves around 4k rpm, while older cars it was about 1,5k rpm. Then they have to pull out the exhaust valve fuse to get the proper noise. They distinguish quite clearly that exhaust valve operation and pops were both altered during time and software updates...

The new facelift F-Type's, they have electric bypass valves and can be manipulated without engine vacuum. So, JLR can keep them open or closed at any rpm via a duty cycle. The "loud" bypass mapping will hold valves open at idle to make it sound aggressive, then close the valves a all the way OR a partial amount, till the higher rpm's which the valves need to open to release excesses backpressure
Nonetheless, we have the ability to change all that. For example, the loud mapping or any others can be set to stay open 100% of the time...etc.
