Default EM options for a 2005 RS???

Ok so I am a relative noob to the NA subaru world when it comes to performance. I know a few things but thats about it.

Are there any "chip" solutions out there for the NA scoobies, specifically for an 05 rs? I wish there was an NA Utec.. That would be sweet...
This is going in the wifes new car (99% chance it will be an 05 rs wagon, which is why I am starting this research) so it has to be seamless and VERY hidden. Which means no safc type deals.

proecm chip - debatable - some say it works, other say it doesnt. It is pretty much a blackbox mod, no one knows how it works. although most likely it tricks the ecu into reading a lower coolant temp etc.

safc2s are debatable(especially on new age rs's) - i had one on my 02 rs. although never professionally tuned, i played with the blue wire mod. didnt notice any difference.

i-speed reflash is just becoming available for certain models www.i-speedusa.com

cobb reflash in the works was supposed to be ready 2 and a half years ago but thats cobb for you www.cobbtuning.com

yoshio factory reflash - sorry cant find a website

unichip's have been used - check www.rallitek.com and www.i-speedusa.com

Perfect power smt6 (rallitek) - www.rallitek.com, www.perfectpower.com
The perfect power seems like a great solution. My car is currently in the shop getting it installed now. It is a piggyback that allows you to tune timing, air fuel, injection control, datalog, etc. with the use of a laptop.
currently you can only tune in Open Loop. Rallitek says they are working to gain control of Closed Loop aswell.


Edited: had closed and open loop backwards

I think the perfect power tunes the open loop (over 4K rpm/ over half-throttle?) and the closed loop tuning was a no-go: http://rallitekforums.com/forums/sho...3&postcount=24

There's also the Greddy E-manage and E-manage ultimate.

But...why? On a stock car, any of these will be very very lucky to get you 10hp. Even on a mildly modded RS, you're not going to get much. For a daily driver, or anything short of an all out track car, the money is better spent else where.

I disagree. Why not spend about $500 for a perfect power which gets you 8 HP instead of paying for a $600 catback which gets you maybe 5 HP, or $200-300 for an intake which gets you 3-4 HP, etc. I think Engine Management is a great bang-for-your-buck mod on even a stock car.

BTW: Cobb says they're ready to try an access port on an '05 RS, they just need a car local to SLC, Utah. So, if you know anyone in SLC with an '05 RS, email Trey at Cobb tuning (www.cobbtuning.com). 10HP for under $400 would be f'in awesome!

thanks for the clarification, had open and closed loop backwards.

Woah, woah. I never said anything about blowing that kind of money on an exhaust or intake. Those are even less worth it than EM, agreed, but none of them makes sense for a daily driver RS. The power to cost ratio just don't make sense for modifying an NA RS.

If you want power from an RS, WRX swap or turbo would be a much more cost effective way to get there. But that's not for your average daily driver.

what happened to cobb releasing a reflash for the pre 2005 imprezas...that definitely got dismissed somewhere along the lines.

What about Megasquirt? It's used widely on Toyotas and Nissasns but I haven't seen it on Subarus - any reason?

I'm going to try and MS my Leg when I do ITBs, but there is some big limiting issue with it I'll use something else.

Common sense would say to leave a new car alone if you want seamless and invisible. If you haven't bought the car yet and want more power...buy the model with more power, no?

Why would anyone waste the amount of money to get into an 05 only to re-engineer the engine management system?
