Cobb stock tune ssv always open?
In the s-dais table: SSV open rpm it shows coolant temp -40 -4 and 32 under those temps it has 3000 in the rpm boxes. Then for the rest of the coolant temps 68-248 it has 0 for the rpm. So does that mean when coolant temp is above 32 my ssv is always open? If it is should i change that? Temp readings are in standard units.

Changed the 0 rpm to 3750 rpm and car seems to idle better and lower rpms seem smoother and bit more torque but no real proof behind it. And this is how all the cobb maps were that i got with it.

haha, well if my worksheet does the same thing for you that it does for me, go to my thread for the maf scaling (*near the top*) and do some wot runs... if you see an OBVIOUS spike around the range the ssv is supposed to open, you will know its working. Kinda a fluke of my sheet is that it will varify if your valve works for you! :P

I'd be interested in this as well, I just checked my tune and my SSV opening RPM value at higher temperatures is also 0. I'll reflash this week and see if it changes anything.

I see the same at mine MAP, did you reach any conclusion?
By my logic SSV is open all the time, after reaching 68°F. Correct?
I'm a bit curious, because subjectively I've always thought my car had a bit more low end when cold.

^Thanks for the fast reply, and sorry for my slow response. But no I haven't verified that it opens. I'm away for the moment and cannot check, is this a common problem?
EDIT: Is there an easy way to visually see that it opens?

Thanks, will do in a couple of weeks when I come home. Can't wait to see if it makes a difference.

Don't waste your time and energy trying to reinvent the same wheel all over again.

Thanks for the heads up, my excitement was to see if it was stuck, not change anything in map. I have a problem area from 3.5-4.5kRPM that I thought might be influenced by a stuck valve. Together with what I mentioned earlier, low end tq seems better when cold.
