Just added 2011

Make sure you take out the ROM start/end tags when you copy paste.

 

Don't go smoothing or changing anything before checking relationships between tables, or working out what it is you're specifically trying to achieve - so you can log before and after, and confirm it is (a) doing something, and (b) did what you wanted it to do.

After any SST change, you then need about 3 hours of "no side effects?" test-driving to do!

Ok, 2008-2011 USDM SST XML in post #2 all updated.

I'll go through my Euro XML when I get some more free time...

 

In my experience this engine prefers smooth tables for any transitional type maps (i.e. flowing in and out of load/rpm/etc). If nothing else smoothing the clutch pressure will help for those odd "what the hell, why did it grab funny at the one rpm" moments (which appears to be those odd little peaks and valleys). Give a nice smoothing over just like a timing table, w/o changing over max/min/shape of the curve.
But I'll wait until I have time to test fully

 

Europe's asleep right now, snooze you loose
Thanks again for everything leading to this moment.

 

If you thought the MAP tables made you want to pull your hair out, wait until you start messing with these.

 

Duly noted, haha

 

Awesome work, was wondering when these would be officialy released. I've tested some of the changes on my 2011 Evo X MR in the Fall and the car ran flawlessly with incredible response out of 1st gear. The snow flew before I could do a good comparison of 0-30 mph times stock tables versus modified but make the right changes and it's night and day. Granted once you up the power delivery you need to watch how the torque hits and keep things realistic but the MR is so much more fun when it can respond closer to real time.

Now I have a few weeks left before I need to tune Dr. Seto's 2008 Evo X MR for the One Lap, plus I'm driving for him this year so I better understand ALL of these tables with as much testing as I can tolerate before it hits the road and track!

 

If your ROM isn't yet covered by Bryan here, you can try an update from goldenevo.com. Some SST tables are now available.

It's not all ROMs, and it's not all the tables... but it's a start.

I'll be solving some of the major "missing table" crimes over the coming days/weeks.


Gimme a shout if there are glaring omissions, inconsistencies, scaling issues, etc. This definition stuff will probably descend into cat-herding chaos for a while... before we collectively get on top of it.

Oh yeah, and if you mix Bryan's manual cut&paste with Golden's SST defs, the ones with the same name can break.

Friends pls mail me any stock 2008 USDM SST ROM to aik_s4@mail.ru.
I need it to make similar xml for EDM EvoX SST ROM's.
I will present it in this tоpic then.

 

Double, sorry.

 

The tables, which named "SST Torque limit 1-3" (and 4 I think) not TPS based, this one Load based. I reflash it on every boost up cars with no problem. For example your car was 360Nm, and becam 520 Nm, you need multiple all the table to 520\360=1.44

 

See here for Bryan's ROM stash...

Those ones definitely aren't load-based!

They are "sort of" accelerator position based... but it's kind of a weird derivation! Definitely not your average axis reference.

Here's a log of me sitting in my car with engine OFF, pressing the accel pedal. I was logging both TPS and the exact variable used as the horizontal table axis...



When you depress the throttle slowly and consistently, it follows TPS.

When you LIFT OFF, though, it gets weird. It will either trail off slowly from its last value, or it will jump up to around the 50% mark and trail off from there.


SST tables are all kinds of insane.

Rich

PS. Thanks for the post - it made me go look really carefully at this. I'd seen it before, but thought I had logged it incorrectly, on account of its weirdness.
