Tuning my 07 sti (manual) 0-100?

[alexeiwoody]

The two are really one and the same, aren't they? I want to prove that my clutch isn't slipping AND causing my speedo to be off by 25km/hr. I think that's bs. I just had the foreman of a Subaru shop - laugh when he heard my clutch might be slipping, after he drove it. He has a 235kw rex.

Rob, you guys asked for a gps video. I'm laughing at how easily matt dismissed it, and no one, not even you said a thing about it.

Anyway I agree, enough of the "he said she said everything is true if it's on the Internet", I'm happy to supply some untuned 1/8 or 1/4 runs. Any suggestions as to where?

in my experience if trannys start slipping they don't magically stop (unless theyre low on oil or have a pressure control issue) they get worse over time

Russia or Greece alexi......that's where drag times on youtube host....since this thread had become an out there battle....might as well suggest out there locations

Justin said there might be a wrx club meet soon, maybe group of us can go. If mine gets sorted I might do a few runs

The more the merrier!

I got more power and better tyres!! plus a pitch stop mount !!! wonder if there are kebabs close by... mmm kebab

My car isn't ready.......I've got clutch slip....

Don't worry. We can tune it out.

It was actually 2 hours on the dyno(I have the start and end dyno times, 6.07pm when I loaded first tune on and 8pm when we got off the dyno, then under 2 hours of road tuning taking into account time to get off the dyno and help Dan shut the factory for a finish time of 10pm, so about 3 and a half hours) which considering I had more 30% more torque@wheels at 2800rpm(388 Vs 475) on my initial tune...

in my experience if trannys start slipping they don't magically stop (unless theyre low on oil or have a pressure control issue) they get worse over time

The transmission actually controls slip, feed it the right numbers and no more slip unless the abuse has been so significant that it is unrecoverable. Everyone goes on about IAM but the TCU has Torque Request Management(TRM) which is the equivalent for transmissions... The ECU will drop line pressure as slip occurs to stop excessive heat/friction. It is possible to 'fix' the slip by tuning the auto correctly and I have proven that on a few cars(around 60 or so) and when the TCU drops TRM, it limits throttle on stalled up launches and the car will barely want to spin the wheels on take off
I know of an MY11 STi Impreza 5EAT with a 20g that previously needed 103% WGDC(lol!) to get it onto boost and end up that the transmission was slipping that badly it was barely driveable, I tuned the DBW properly and had to drop WGDC to 45% as it actually let the turbo spool and make torque. With 4 big blokes in the car it actually had wheelspin.

Everyone just assumes crank up the power and make power on an auto.... look at the boosted V8 Commodore guys or the XR6T's and wonder why the tuners spend so much time getting the transmission to hold the torque.

off course transmission controls slip... that's its job... if the tcu isn't telling the trans its got more torquebeing applied then how the hell would it know how hard to clamp the clutches to make a soft shift or heavy. if a pressure control solenoid plays up you may get flared shifts as I said in my post. its a bit like a shift kit isn't it!! in alexi case how on earth did it magically stop if the tune was the same....

I don't believe u had 4 blokes wheel spinning.. matt you need to stop saying that stuff cause people think youre full of it

[alexeiwoody]

Matt says that it's still slipping though. And that's what we'll be testing.
