I remember those early threads, many guys did hit that magical torque limit and their clutches started slipping and going into limp mode. Those were indeed iffy times .

One of the first guys to slap a FP Red turbo (I forget who, was on here though) on was met with, "Your trans is going to explode. Have fun replacing it!" However, I was mainly referring to mildly modded and close to stock situations where the SST **** the bed early on and needed replacing, not upgraded clutches or an upgraded cooler.

 

Oh I gottcha.

I wouldn't say I was going easy on the car when I developed heat issues, but the car was 100% bone stock. Second transmission was fine, never even got close to developing that much heat, which leads me to think it was a real defect with the original transmission.

When it really started giving me problems, revs, clutch's opening, limp mode, the transmission was already gone at that point. I did have to limp around in the car for a week while I waited for the new transmission to be shipped in from Japan.

 

There is a bit of clarification needed in the last several posts. Don't want people to get the wrong impression:

This was all tuning related issues. There were so many built in limits (torque, load, airflow, cpru, etc, etc) that is was impossible NOT to over do it.
Additionally, first gen everything has glitches, hence the importance of early adopters to ferret them out.
Amazing how far we've come in 3-4 years

It's a lot more than possible, it's virtually guaranteed at this point. Limp wrist driving has been the cause of MOST SST issues in the last several years. It's the nature of a "saving gas" mode rarely operating in the correct temp and/or rpm/load range.

While "beating" on anything technology is never good, aggressive driving is just what the doctored ordered. We still hear about "SST OVERHEATING" issues on track, but that is not an actual issue, it's a preemptive warning system (despite the owners cursing about it). Hell, I even had a friend KEEP pushing past that point intentionally until the SST literally disconnected from the engine. After 10 mins of cooling the car was back to normal. Half a dozen track days later his only problem has been frying his wiring harness due to ex mani bolts backing out.
This SST is just about the toughest thing I ever driven. Coming up on 40,000 miles and I can honestly say it drives better now than it did at any time in the past.

 

^Well said, sir. Couldn't agree more.

 

The following are two very different things...


Exhibit A: An SST that is just plain dog's breakfast wrong, even with fresh fluid, with ECU tune right back to stock. We can choose whether or not to include dead clutches in that... but let's leave that can of worms unopened, eh...

Exhibit B: An SST (due to TCU or ECU action) doing stuff in response to an altered ECU tune... whether for self-protection, because of increased torque, or weirdie side-effects... sometimes all of the above!


It's not common to go off to a trackday/dragstrip/canyon run with a working SST, and come home a sad panda with "Exhibit A".

But... it's been totally, utterly, groundhog-day common to wave EcuFlash around like a giddy schoolgirl and end up with "Exhibit B". Ask me how I know! But we're getting a lot better at SST-related tuning, honest.


Some final food for thought...

With all the tuning sins and beta testing we've inflicted on our SSTs, how many have failed? AFAIK, zero. That's pretty cool, when you think about it. How tough are these things, that they can withstand US?

EDIT:
By the way, I zeroed out RRI-A, the more throttle I give it the faster it accelerates off the line (1 to 2 and 2 to 3 feel like all subsequent gear shifts, fast to the point of almost being rough)

 

RRI-A? Details lol

 

Ramp Rate Interval-A
All the good SSt stuff is on X

 

Hmmm Looking at my SST table for the RA and I dont see that in the menu... =(

 

Download a new XML from goldenevo.com - I added the defs earlier this week!

New SST tuning tables are...

SST Throttle Requested Torque Ramp Rate Interval A
SST Throttle Requested Torque Ramp Rate Interval B

Details here.

If memory serves, I tweaked the latest base map betas and copied the USDM ROMs' tables (which were nice) to the non-USDM ROMs (which were sloppy-throttle central).

sstevojr is going totally off the reservation, of course, and has just set his 'A' table to all zeroes... presumably to find out if his RA asplodes.

Do NOT go setting both A and B to all zeroes. In fact, just sit back and let the insane people do their thing. Not mentioning any names. sstevojr.


But sstevojr, I honestly don't think those tables do anything unless throttle is in the process of being increased by your right foot. The code says... it's not involved in upshift feel. It's a brief ramp-up of SST torque calc stuff as you stab at the throttle... not when gears shift.

Anyway, derail alert! This thread is officially at risk!

In reply your reffering the the 4's and 7's Correct? I'll test it out myself tonight and see what changes.

 

I'm running my AUS-EDM rom on 4s and 7s now, and love it. USDM owners always had these numbers - it's so much more responsive that way.

If you want a safer test than zeroing stuff out, try using the ADM values in "Interval A". See how crap my RA was until recently, lol.

My stock table was... 4/4/4/4/4/8/8/12.
