Thought you guys might get a kick out of this.

I took the shift lock button out of another shift assembly I had laying about, mounted it in the blank space in the bottom of the bezel, and mounted a push click on/off switch underneath it - which is tied now to a ground and the specified pin on the TCU harness.

:cool::D:cool::D:cool:

Does it work??;):D

If it does, you now have the same set-up the Japanese have on their cars.

Nice one!

:)

Nicely done, DarkHelmet.

I like the label by the button.

That looks like a photochop.

It should read LUDICROUS.:)

Label printers should have a spellchecker

;):D

Yup, its a photoshop.... Now I just need to print a label for it, and a silk screen for the dash that says ludicrous speed. And find out some what to get a blinking light in there that says gone plaid over 100 mph.


Oh, and I hooked it up last night, really makes the car feel peppier, and a lot quicker to down shift

So would the effects of this mod be cancelled out by installing one of the ECUTune chips?

Is power mode bypassed by the chip's tuning?

Or would this enhance the experience provided by the chip?

Or does the ability to have full-time Power Mode make a Stage One ECUTune unnecessary?

Gee, Troy, that's a lot of questions.....:rolleyes:

The ECU-tune chip mod acts on the ECU, the engine computer.

The Power mode switch acts on the TCU, the transmission computer, and modifies the firmware in the TCU, has no effect on the ECU or engine tuning.

Stage One EcuTune seems to enhance the engine response, possibly liberates a little extra hp. Those who have it are pleased with it. The Power mode switch will add more to that responsiveness, and will work well with the chipped engine.

Your last question is a hard one; it depends what you want.

In terms of pure cost, the permanent Power Mode switch is the cheapest thing you can do to make your car drive better, give more response to the throttle.

The EcuTune chip is sure to sharpen up your engine a bit, you would have to weigh the cost of it against the improvement it made, but it is easy to install.

In terms of bang for buck, the one thing you can do for your car to get more power to the wheels, to make it go harder, is change to a 4.44 final drive. This will totally transform the car.

My favourite combination would be the 4.44 gears plus the permanent Power Mode mod. That combo would keep you smiling.

Joe:)

Stage 1 + intake resonator gone + intake spacers + sti panel filter + 4.44's + power mode button + lightweight tires and alum wheels + crush mod =

An SVX the resembles the factory car very little. Lots more fun in the twistys, because with power mode, you're almost always in a sweet spot no more reluctance to kick down to a proper gear. 4.44's mean that sweet spot is teh fastar! I don't have problems breaking loose anymore, especially when I get excited in the turns*

*Closed course, professional driver do not attempt.*

*You know, unless you want to. *


*Just dont come whining when you try to drift a 3600 lb AWD car and end up upside down.*


*and don't do it in a school zone, keep it on the track

That's a nice break down Next. What if you added intake mods like port and polish, gasket match and then give the suspension konis and coilovers? Sounds like a fun ride.:D

I think he was just listing thing that he had actually already done. Certainly those you mentioned would improve the experience even more - especially the suspension! :cool:

I agree, nice breakdown, and thanks to Joe as well for reinforcing this line of thinking.

I've thought a LOT about the 4.44's but I also love my high speed highway cruising. The car is just so perfect and smooth (and quiet) at 70-80 on the freeway and it's ability to accelerate from that to triple digits faster than just about anything else on the road. Not sure I want to give that up. :o

WestCoastSVX 12-21-2007 12:56 PM

Hey Patrick - The intake spacers and STI filter.... I'm assuming those are related? Is there another thread where this is talked about? Sounds interesting, but don't want this one to get too far off track...

nextse7en 12-21-2007 01:33 PM

edit for questions...


The Spacers. http://www.subaru-svx.net/forum/show...onelic+spacers

The filter is just a green sti filter in my airbox, and it does more for my head than my car.


I was just listing what I had done.

4.44's will out accelerate a stock svx to 100. and to 150... sometime around 155 I redline, and a stock svx runs outta juice, so it goes.


I also average 25 mpg in winter at 70 mph. The tach is at 3k at the point, and the engine is barely noticeable, going faster adds a pleasant engine purr, that turns into a growl. :D

Really the gearing the car should have had from the factory. Really becomes a corner eater. The biggest complaint I had before my mods was that the transmission was always playing catchup with the engine, especially coming off the apex in corners.... Now power is always right on, and usually in the gear I would have selected if it were a manual.

Troy, the US stock gearing is 3.54, really a very,very high overdrive. The UK and JDM ones use 3.70, and from my experience of both, they are still too high for the power and torque the engine puts out, plus the weight it has to push along.

My Twin Turbo Legacy had 4.11 final drive, and it was an excellent compromise between low enough bottom gears to get the mass underway, yet high enough top to make cruising pleasant.

Now I also have experience of 4.44s from my brother's Forester Turbo [250hp] This really shifts ass when you hit the pedal to the metal. However, the gearing in top is low, but acceptable.

I reckon if you felt like a change the 4.11 gears will surprise you how hard they pull. However for sheer grunt, the 4.44 wins hands down if you can live with the higher revving when cruising.

Joe
