Hi Guys,

As promised here are *some* of the results from my SST Dyno testing.

Bryan@GST already posted up some data, but I figured I would post up my findings regarding clutch pressure and slip rates when changing between Normal, Sport and SuperSport transmission modes:

Normal:


Sport:


SSport:



Summary:
SSport really cranks up the clutch pressures over Sport and Normal and this really eliminates clutch slip.

Car:
2008 EvoX MR
TBE
3port
Cosworth Filter
GTX3076R
98RON
All pulls where done in 4th gear on a Mainline Dyno.

Thanks to Cobb for sponsoring my time and thanks to RoadTrackRally for the dyno time

 

I need graph reading 101 for dummies. Can you explain where the torque is or is that not a factor?

 

Now you know why I wish I had, and really need, S-Sport on my RA.

 

So what i got is that S-Sport is less abusive on your clutches? Am I right to get this conclusion form the grahps if so then i should be in S-Sport all the time(manual) as to not be red lining all the time?

 

Very interesting; thanks for posting these!

 

+1. Thats what Im getting from it also

 

I drive in Manual/Sport at times, only cuz I don't have S-Sport
So how about that TCU.....

 

S/Sport lets them slip less, yes that's correct.

but as you also know it makes the shifts more abrupt
If you can live with it, S/Sport will technically look after the clutches better... that's what i get out of this data aswell.

Personally i either drive in Normal/full auto / granma mode , or S/Sport full kill mode
I don't think Sport ever gets engaged, except to switch from one to the other.

 

Thanks for the info
I make my tune on alt map and will switch it on only in s-sport mode,
hope my clutch will live long life!

 

Well I have been able to tune out the slip, but thats info for another day/week/thread

 

It´s GREAT!

Is there a chance to enable selecting S-Sport during driving?

I usually use paddle shifting, but I get really angry when I take off and then realize I did not change the shifting mode and have to stop to change it....

 

Well, the abrupt changes of S-Sport might also be harder on the transmission itself and the rest of the drive-train. So it's a trade-off of clutch linings wearing faster or transmission gears, bearings etc wearing out faster, IMO.

 

Good stuff man. Always one step closer to fully understanding our cars.

 

Could the ECU be hacked and S-sport mode inserted cause that would be really amazing?

 

Or best yet, I would love to tweak the NORMAL mode shift points to occur a little later and the SPORT mode shift points a little earlier. The two just seem a bit too far apart on the docile to agressive scale and I find myself either in NORMAL or MANUAL modes exclussively on the street.
