Guys, has anyone got a log of completly stock evo 10 with SST gearbox, sst clutch pressures and clutch slip ? Could anyone share it ?

Also what do you think, what is acceptable clutch slip for normal, sport and supersport mode ?

 

guys, maybe someone could post a log of a stock evo X in normal / sport /super sport mode ?

 

not sure about the MR, but this is what my GSR was doing when the clutch started slipping...

 

guys, has anyone got clutch slip sleep numbers and clutch pressures for stock Evo X on normal / sport / ssp modes ? Maybe a log of completely stock car ?

 

i have for my 09 ralliart. In Sport mode at the drag track i saw slip speed values up around 4000 at launch and for most of the run, if engaged, slip held nicely at 0, when not engages slip was between 1000 and 1500 depending on which gear i was in.

Clutch pressure was around 8000 on launch and shifting into 4th landing at 4krpm is saw a peak around 12000.

i also had 1 run where i got the slowdownmsg on launch and in the logs slip speed was getting up to 8000 before clutch pressure was even starting to ramp up which = lots of heat and the car politely telling me to get my act together.

Dunno if thats what you were after

 

Sorry for "digging up the grave"

but I'm also interested in this topic and when I try to search I found this tread.

Is there any known figures about the "proper" slipping rate yet?

and when I was logging mine, I some times got negative numbers on clutch slip and some impossible figure like 65238 on input shaft, any one knows what's the problem?

 

For the little I know, under full boost, correct slipping rate is low number as possible: 3 - 5; in my case 2.5.

 

just come back to this tread and to say: thanks bro!

I'll try to log some figures later, I'm switching my tune from EcuFlash to Cobb these days

 

You're welcome!

 

Max clutch pressure normally obtainable in the SST after ECU torque reporting is adjusted is in the 15-15k mbar range. Typical acceptable logged slip rate should be no more than random 5 in among a lot of negatives. Anything higher than that is to close to the maximum torque threshold and can result in uncontrolled slip events. If you are not close to 15000mbar, and your ECU has already been properly adjusted, then there is a pressure issue.
