When I get my car (be it an STi or Evo) it will be done by Vishnu because I am of the opinion that they are one of the finest tuners. That being said where the heck is the update on the STi progress, I mean its been almost two months since the initial dyno results and my sanity is about to run out. I'm not asking for three performance upgrade packages just something to keep me excited about Vishnu or at least offer some sort of progress report thus far. I don't know guys I don't think this is too unreasonable. What do you all think?

Kudos to Shiv and all of those in Vishnu

 

Why is this being posted here? If you are going to ask a question about the Sti you might want to try www.NASIOC.com

Hooray for high prices!!

 

lmfao!!!

 

Perhaps this is being posted here because there is relevance, in that Vishnu while they are associated with Evo's so too are they associated with STi's. So it would follow that those in the know of Vishnu (perhaps even Shiv) could perhaps respond in a helpfull manner. And by the way I do know of the link which you have provided and there are other cars discussed here. This forum is not completely for Evo's but more for intelligent driving enthusiasts, at least that is what I have gathered.

 

point taken, but it just made me laugh

 

man screw horay for high prices... im down for horay for b00bies

 

Actually, this forum specifically is called "EVO General", not Shiv or Vishnu general (BTW, doesn't he have his own forum?). Guess what....we also have a forum called "Other Cars" for non Mitsu stuff. I'm not saying what your looking for is not a valid question. I am saying this is the wrong place for it.

The problem facing STi tuning is its ECU. It's completely new. So new that we don't expect it to be sufficiently cracked for at least another 3-4 months. As always, we are also doing XEDE testing and hope to have some prelim results by the end of the week.

Great it's another brainwashed Vishnu freak. Good luck getting support with his software ... oh u could always settle for o his highly conservative base maps.

 

Base maps are a good starting point for many. If someone is compelled to they can tune it to the brink. Nothing is stopping them. The tools are available.

 

Hope you don't mind me posting this Shiv

Hi guys,

Well, we got our STI turbo-back fitted to the test car. In case you forgot we dyno'd this stock STI at 210-215 wheel hp and 220ft-lbs of torque with audible detonation between 3500 and 4500RPM. Peak boost was 14psi, falling off to 13psi by redline.

Next, we added [and tuned, of course] an XEDE. This brought power and torque up to 235 wheel hp and 240ft-lbs of torque with zero detonation and perfect consistency. Peak boost was 15psi, falling off to 13psi by redline.

Next, we installed our 3" STI turbo-back and retuned the XEDE. After a bunch of tuning runs, output steadily climbed to a ridiculous 260 wheel hp and 272ft-lbs of torque. Yes, 272ft-lbs of torque. This is more torque than ANY WRX we have ever tested short of our two Stage 3 test cars running race gas. Our 12 second Stage 2 WRX, at best, make 220-230ft-lbs of torque. Even those that run 110+mph trap speeds. For another comparison's sake, a stock WRX makes a peak of just 165ft-lbs of torque. Peak boost of the Stage 1 STI was 16psi, falling off to 13psi by redline.

The Neat Part:
In fact, comparing the Torque and HP curves of a Stock WRX to a Stock STI to the Stage 1 STI, it becomes clear that the difference between the stock STI to the Stage 1 STI is virtually the same, across the board, as the difference between the Stock WRX and the Stock STI. Yep, it's that significant. And no knock either.

Once we get our scanner up and running, we'll post up charts. They speak louder than any words I can come up with. Geez...

Here's some rough numbers (from looking at the graphs) just in case anyone wants to plot them on an excel spreadsheet to see what I'm talking about. I hope it comes through okay.

Wheel Torque

RPM- Stock WRX - Stock STI - Stage 1 STI
3200- 135 - 165 - 250
4000- 165 - 215 - 270
4800- 160 - 205 - 260
5600- 155 - 200 - 245
6400- 120 - 165 - 200


Wheel HP

RPM- Stock WRX - Stock STI - Stage 1 STI
3200- 80 - 100 - 150
4000- 125 - 165 - 205
4800- 145 - 195 - 240
5600- 165 - 210 - 260
6400- 150 - 205 - 245

Cheers,
Shiv

PS. All testing done on 91 octane fuels. Can't wait to see what happens on 93/94 and then on 100+ race gas

 

No problem

cheers,
