So where is the TCU located?
I have read some thread that state that the MR tcu can be installed in a RA for S-Sport. So where would the tcu be located if I to look for one? Thanks!
Dug around on that interwebs and found the service manual. It's inside the side pan of the trans. =)

Don't forget, you have to change the internals of your RA transmission too. The 5/6 gear of the X trans are larger than the RA. Also the MR TCU can't be from an 08/09 MR because the TCU doesn't have 'learning' capabilities.
S sport is over hyped. As a matter of fact, because the launch control on an MR can't be changed, the 'tap' method in Ralliarts works better! Also all super sport does is shift at the redline in automatic mode.
Get you SST RA sport mode tuned for line pressure, slap it in manual sport mode and shift yourself at the redline. Don't waste time/money on an MR TCU swap. It's not worth it at all.

Nah, from the clutch-slip logs I've seen from S-SPORT dyno tests (see EvoX "share the love" thread, lol), I'd be wanting an MR TCU if I had loads of extra torque. It's a really noticeable difference.
If you see clutch-slip bouncing around above zero, you're not in S-SPORT mode.
Beeble and others have logs of some S-SPORT MRs (not all) hitting over 200psi of clutch pressure. Which is a lot.
Yep, if I had some funky big turbo fitted on an RA, I'd be hunting for an MR TCU.
edit: Haha, Jasoob, I just saw your other thread about all the POWAH bolt-ons you're planning. So I guess you'll be neck-deep in all this with your own ride!

I would kill for MR line pressure that the S-Sport mode provides. You currently *cannot* get it with the RA Sport mode, even fooling around with in-direct line pressure tweaks.

Also for the launch off the line without launch control you can place 100% TPS limits at 500 & 1000 rpm and then 1500 set 30%. Then at 2000 rpm + set it back to 100% tps limits with it tapering down past 6000 as needed to allow a clean shift to 2nd. Turns out ths action of going WOT and letting off and back to WOT gets the car off the line much quicker, now simply pinning the gas pedal sends the car forward with authority after less than a second delay and no launch control needed.

Will try.

Is this the 1st Gear TPS Limiter table we are talking about? I don't see 500 and 1500 RPM for my table. It starts off at 1000, 2000, 2500, 3000, 3500, and so on.
Did you rescale your RPM axis?

No, mate - you have!
I'm looking at the stock version 53050009, and a copy of one of your personal 53050109 tunes, and your tune has a rescaled axis.
By the way, this scale is used by a lot more than just this table...
Boost Target Engine Load (x 3)
Reactive Solenoid Base WGDC Map (x 3)
Passive Solenoid Base WGDC Map (x 3)
etc.
