yup, same sight, right under the other one.


EDIT: I realize it's not the best sight, so I just updated it to make it easier to find what you need.

Am I the only one who can't get the equations for the Temperature out to work? Even the plugged in numbers don't match up.

I am a MechE who has taken Thermodynamics, the equation looks right (from a glance) but whenever I plug in numbers, even the ones given, I don't come anywhere close to the values.

Be more specific, are you talking about the boost part? What equations?

The Tout equations on Page 9 for Boost.

For example, plugging in the numbers for the LowBoostTout into my calculator gets me 824.805, nowhere close to 188F, even subtracting 460F (where did this number come from as well?) doesn't yield anything.

Ah, I see now for the 460 part. Sorry, I do pretty much all of my work in Kelvin.

just harrassing a fellow ME, I just took a quick look and I hear you. I don't know what I'm missing but lowboost is 365F and high boost is 544F for T out.
I'll re-read later.

Got it figured out.

The equation should be like this:

Tout= Tin + [(Tin*(-1+(Pout/Pin)^.263))/Efficiency]

NOT like this:

Tout= [Tin + Tin*(-1+(Pout/Pin)^.263))]/Efficiency

Alright, updated the guides with the corrected equations. Thanks MConte05 for pointing this out.

Default thank you!

Wow,that's some great data assembly you've done there. Not quite comfortable yet with the idea of potentially scrambling my car's brain, but the directions are definitely there.

Awesome post, I am just getting into opensource and although I most likely won't be messing with any tables it is great to see what is really going on.

The only time school is expensive is if you drop out.

That requires a hacked ROM. There is one floating around for a particular year, and cobb supports it on the '08 STi. Other than that, you need a standalone EM.

In other words, you can't just tune SD into our cars with a standard ROM.

side note:

There's no reason this isn't a sticky at this point!

While I have nothing to do with whether this is a sticky on Nasioc or not, the reason I haven't made it a sticky at the romraider site is that the document, which pretty much almost entirely paraphrases information from other people's posts, fails to adequately reference the source of this information. Each section should have a set of links pointing to the threads and posts where the information was obtained IMO. I've said this several times before, but apparently the author doesn't feel this is necessary or doesn't want to spend the time to do it.

Or he has done just that, it's at the end of the post here, and you missed it? (Is it different over on romraider?).

For the links links you feel were "left out", have you or anyone else provided those links or just complained without reference to what? Bad noodle took alot of time putting together all this scattered information. I didn't see anyone else taking on that initiative, but rather expected everyone to spend countless hours sifting through garbage to find what they are looking for.

So it'd probably be a good idea to read their posts and listen to their advice. I tried to keep a list of the sources that contained good amounts of info. The rest of the info i found scattered throughout posts.
