air suspension, turbo lag

[audi12345678]

Hi,

Does anybody know, can you make ( program ) the S6, S7 air suspension little stiffer, harder, it feels too soft and there is very much body roll, even in dynamic. Also the turbo lag bothers me, does apr ecu flash remove it?

Can't really answer all your questions but a lower stance will reduce body roll and a stiffer suspension will as well

It's important with the S6 to keep the tire pressure at the upper limit. This helps with the handling. I run 46 in the front and 44 in the rear. In the future, if I keep the S6, I'm thinking about upgrading the sway bars.

Re the turbo lag, more likely throttle lag, what model/year do you have? There are TSB's for earlier models and in the MY16 model, this is a lot better.

What's your baseline for body roll and stiffness? Turbo lag is not exactly a turbo lag but rather throttle lag that is implemented intentionally since S6/7 is a luxury car before sport car so they don't want it to be too snappy.

You can lower S6/7 and install sway bars and end links to combat body roll but it will not go away. It's a physic that C7 is a big car so the mass is there to be transferred. I'm telling you that even a supposedly ultimate car for C7 body like RS7 will still give you a feeling of driving a big car though it feels smaller than its size.

I would say if you want a more snappy throttle, stiffer, and less body roll, you may want to check the cars with smaller body.

I drove Panamera GTS, its even bigger than s6 and s7, but it feels small and does not have body roll because the suspension is just so good.

The size of both cars are almost identical. I don't know what kind of suspension in the panamera gts you drove but if it's spring setup and you are in Europe so maybe you can ask if the DRC is available in S6/7. That will give you a better handling but I can't say if it will be good enough for your liking. Anyway, it's not that surprising for Porsche to drive better since they are well known for making sport cars so they would give priority for their cars to be sporty.

Maybe if you can get over the look, Panamera will make you happier to drive every day.

The way the headers and intake are designed on this car, you literally can't have any LESS lag from a physical design standpoint. It's more a function of the turbo itself spooling with the factory tune, which is controlled by the ECU (lower boost at lower RPMs).

Yes, the tune helps this A LOT, as it increases the boost pressure much lower in the RPM range, which DRAMATICALLY increases the torque in the low RPMs. It's quite a significant difference.

Like other said, sway bars apparently make a huge difference in body roll... I haven't done that myself, but am thinking about it!

Panamera GTS rides on air suspension, but the sport + setup makes the car very agile and direct like some hard core sport coupe, but on the s6/s7 there is not much difference between comfort and dynamic, it feels like floaty boat all the time.
DRC is not available for some reasons. Maybe a stupid question but is it possible to replace the air suspension with coilovers?

[VeryBadman]

I wouldn't say it's impossible to do so but the cost will be incredibly expensive. That's why I said you may want to consider getting a panny instead if you can get over the look.
