I have a 0-60 vid. according to the video, I go 0-60 in about 5.6 (zchip)

 

I thought one of the big differences between the RA and MR was that the MR had S-Sport mode and launch control, while the RA had neither (just Sport mode). So DON'T ask the MR guy's what they do, because the launch control system they have doesn't apply to the RA

Just got to 2k miles on my RA and will take it out for a practice of launches. Will let you guys know how the car fairs afterwards. If she breaks after a few launches then it's bad engineering right?

 

^ Not necessarily. Remember, the RA's tranny wasn't designed to launch at all. If you notice, when you stomp on the gas from a dead stop - the car creeps forward at first for a second or so, and THEN will it take off. I wanna say that this was designed into the tranny system to reduce shock to the driveline, which extends life.

As Otter said a couple of posts back, the SST is not like a typical auto tranny that has a torque converter that will allow the engine to rev while the gears sit still. So for us, engine rev = gear spin, even with the brakes applied full-force. Brake-torquing seems like it will be more harmful to the RA's SST...

My question is, if the RA and MR SST's are virtually the same internally (minus 5th and 6th gear ratios), is it possible to do a "software upgrade"? You'd think the RA's SST would have S-Sport in its system - but was just disabled, and a software fix would allow us to toggle to it? Who knows, until someone finds a way to hack the ECU I guess we'll have to wait.

 

They're supposed to be the exact same trans. I imagine one of the companies doing flashes could tell you if the MR's launch control is something they can program into the flash or not. I guess it would depend on whether it's the ECU or something else controlling the trans.

 

I understood it that the primary ECU that has been 'cracked' is not what control's the SST. There was a 2nd ECU-like piece of hardware that was part of the closed-loop system that did all that. IIRC, it shared some data with the ECU, but not a whole lot, so controlling things and flashing of the main ECU won't let you influence the SST very much.

Could someone reverse the 2nd system? Sure, but none of the reputable shops have started messing with the SST control from what I've seen. Asking expert engine tuners to start dabbling in the new world of automated dual-clutch transmission tuning is pretty ambitious. Doable, but the risk is too high for an area where no one really has any experience to lean on.

Lots more info in the X forums.

 

Very annoying indeed. It seems like the car stops to think "do I go or do I NOT go!?!?!?!" annoying... very.

 

Actually I was wondering if we'd be able to hack into S-Sport mode as well. Cause like you said our cars have the same SST as the MR's. It should just be a matter of unlocking it somehow.

 

Just some food for thought. While yes yall do share the same transmission as the Evo X, yall do not, however, have the same drivetrain. Remember, it is, or based off, the Evo IX drivetrain setup. Not sure if the IX's had the S-Sport mode but maybe its something only the X gets cause of it's unique, own drivetrain setup and because of the Ralliart/EvoIX system, it just doesn't/wouldn't support the S-Sport mode. Just my .02

Than again, I may be wrong. Very interested in a Ralliart, if anyone wonders why I'm posting up.

 

Ah, very true. I forgot that the drivetrain setup is from the IX...that might just throw a wrench into the whole idea.

 

We might find an Evo IX owner to find out. Not sure about the IX's drivetrain specifics myself. But I do remember seeing we have it in our RA's.

Foiled by the man again.

 

I'm confused what does the software for the transmission have to do with the bits on the 9? AFAIK the 9 did not come with the 4b11t or the tc-sst. We should have the same rear diff as well as the same center and front diffs. Maybe slight differences.

 

The only difference that I know of between the IX and x awd system is the AYC, this should have nothing to do with adding a s.s. setting (faster shift points) or launch control to a electronic program.

 

Not trying to start a debate but I was just giving what I was thinking. Launch control I can see being added with no problems but what exactly does S-Sport do? Quicker shift points? Mk, well..yea that can easily be done. But is it as simple as just "unlocking" the feature where-ever it hides? No one know's right now. I was just stating the fact that there might be a reason why Mitsubishi didn't put it in the Ralliart. Maybe it does have something to do with the AYC. Than again maybe not. Only time will tell once someone "unlocks" the TCU/ECU and gets further into the "workings" of it.

 

"Super Sport mode boosts performance and quickens shifts yet again. Additionally, it is designed to hold the revs above 4500 at all times. With each sportier mode, the shifts are more noticeable, however still as smooth as the best standard transmission shifts. The super sport mode really shows the liveliness of the transmission and engine."
