I can't speak for the 07 2.5i's, but I have tuned my 05 RS with enginuity and i don't see why it would be very different. From my knowledge all you need is the tactrix cable and the program and you should be able to do it.



And I can tell you that with my new tune it truly feels like a different car. Raises the torque curve across the board. Do some more research and give it a shot. I promise you will be happy.

yea that's what i'm hoping...from what i've read, it seems like the cheapest and possibly easiest way to gain hp and torque. $80 isn't much if you can FEEL the difference!! of course i would add some extra goodies later- or maybe before...

Yeah, before the tune I had an Injen CAI, Borla Replica headers and a 2.5" catback and it ranw ell. But as soon as I did the tune it's like all the aftermarket parts started working together like they were meant to and the increased torque was MORE than noticeable to people riding in the car.

uh-huh! i'm salivating thinking about the gains from this.... did you have someone tune for you, or did you learn the hard way? reading some of the threads, it seems like everyone's egos get all fired up and nothing ever gets accomplished (which is hilarious) but i need some literature or a tuning for dummies book. does the stock map help at all once i plug into the ecu?

Read this:
http://www.amazon.com/Modify-Managem...1877363&sr=8-1

Looking at the stock map is interesting, but it isn't going teach you tuning strategy. Succesfully tuning a car is more than changing just a parameter or two, you have to consider AFR/Timing/Knock Correction/OL-CL/list goes on and on... To result in a SAFE net gain you need to understand the knock strategy of the car, do a fair sure of logging, and ideally spend some time on a dyno (in a perfect world of course).

Sc00ter- did you ever perfect the 91/92 octane map for your 05? I'm gonna try to get some dyno time in the next few weeks to see where I'm at and perfect a 91 octane tune (with some help of course)

Chk out the Engine Management and tuning forum... they have a section on Opensource ECU stuff like enginuity, etc. TONS of info there. And the best advice I can give is LOG, LOG, LOG.. and then LOG some more.

He's already been into the Open Source Tuning forum. He didn't like the answers I have him.

To the OP, do you even have any mods? If your car is bone stock, you're not going to see any power gains from tuning. You'll pick up some part-throttle drivability if you tweak the right stuff, but no more power.

williaty- it's not that i didn't like your answers bro, i just want to learn, and at first you were very vague. i appreciate yours and others advice and tips. i just thought if anyone had done a similar tune, it would be to my advantage to see what they have experienced.


edit: i haven't done any mods yet, what would be the most beneficial before tuning? i know a cai will help w/ air flow. wouldn't i need a better exhaust too?

If/when you do an intake, you'll need to check that the MAF scaling is still correct, so you'll tune after that. Both headers and HFC can possibly increase the max engine load enough that you'll come off the top of the stock tables, requiring a re-scale.


BTW, don't buy an intake until I get my study of them published in the next week or so, there's going to be some surprising stuff.

ok, cool! which cai's are you testing? my next mod will actually be an intake. i was debating between cobb or injen, but before that i'm going to get the tatrix cable and log before my mods and in between any others to see the results of each. would it be smart to get a better set of headers also? i just bought the book that sc00ter recommended so i be familiar with all the jargon. it will be interesting to see the results of your study...keep me posted!

I haven't tested any one specific CAI or SRI, they're all going to be very nearly the same. What I've done is CAI/SRI vs snorkus delete vs. stock vs. hybrid.

It's the CAI/SRI and snorkus delete that cause the major problems.


Headers.. EL is it. Techworks is the only ones making EL headers right now, so the choice isn't hard.

No, the Borlas and knock-offs are unequal length, which is not as good for making power as equal length. UEL Borlas are still better than stock, but TWE EL headers will knock anything else into a neatly cocked hat.

I once heard someone say "The first 100 horsepower are cheap. It's the next 10 that are going to cost you." Everything TWE sells goes for the next 11.

i have a set of their 4-2-1's and im waiting on stromung cat and catback so ill let you know what that extra 11 hp feels like. Cowboy - dont forget that you get what you pay for. (unless you find a previously owned and never installed set that someone really really wants to get rid of... then you get more than what you pay for) And the Borla UEL stuff will give you a nice sound that many enjoy with or without the extra powergains.
