Default JDM Swap into 2.5RS = Better than sex.

The pictures speak for themselves;







Mods;
Blizzak Revo1 snow tires
Full tank of gas (2.5gallons of Turbo Blue 110 leaded, remainder 93 octane)
Spare tire, Car Jack, tools, floor mats, etc...
For the 1/4 mile I had a passenger. Launched from 4000RPM, bogged down.
For the 0 - 60 I was by myself and launched harder. No appreciable tire spin either way since the roads were dry. Ambient temperature was high 20s Farenheit.

I never thought I would own something this fast while still in college!!!

More stuff on the car if you haven't seen already

The pictures say that you're using an S-AFC. Thats a no-no...

As much as those Apexi G-meter tests aren't really that accurate...that looks real nice.

Its an S-AFC2; I bought it for its knock monitoring feature, but ended up using it in conjunction with my wideband Air/Fuel ratio meter and EGT gauge for some tuning. It works perfectly. Remember; this is not a US-Spec engine. JDM ECUs (at least older ones like my '99 Version 5) are a lot more tolerant to piggybacks.

Did you not do this before?

I am certain that I got my ecu pinout from your site.

Either way, luck you

Well the S-AFC2 is little more than a cool looking gadget that adjusts your MAF signal (which is a ****ty way to tune, wideband or not). A much better option is the GReddy eManage, while being a little more involved to install, it gives you control over timing, injector duty cycle, and also MAF correction. The eManage Ultimate also gives knock detection/correction, individual injector correction (plus and minus fuel, also) and a boatload of other features.

I've never heard of that show, but good for you. Also get that chick off your hood, she's scratching it.

Minor detail you forgot;
The Greddy e-manage costs about 6 times what I paid for that S-AFC.
The installation is nothing; I wired that entire engine myself by hand. Its just a matter of cost-benefit; the stock ECU does great for now and I don't have the money for a standalone, so the S-AFC2 is a good way of cheaply monitoring knock and doing minor adjustments to my air/fuel curve.
Sure, there are much better ways to do this, but you get what you can afford
BTW I wouldn't bother with e-manage in the first place; I can get an Apexi Power-FC for much less to do all the same things (AFR, ITC, Boost, etc etc)

Unless the S-AFC cost you less than a hundred bucks, I think you're mistaken. Besides, you at the minimum bought a JDM complete engine, a project you can't really do "on the cheap".

If the engine is stock, any adjustment to the MAF sensor you're making is semi-pointless. You can monitor knock with a TXS KnockLite ($120). Or since you have a wideband, you can get knock detection in the whole package with the TXS Tuner.

I don't know how the Apexi Power-FC works (since this is the first time hearing of it, must not be commonly used), but the eManage has been proven on many Subaru ECUs, including the new WRXs (even though its pointless with the UTEC), and I'm not sure what you mean by ITC

you can get s-afcII for 200...emanage is at least 2x that. If you lucky you can get power-fc for a little more then a emanage and it is way better. too bad they dont make um for the usdm subarus

I've seen cars go low 11s on an SAFC 1. There are better ways to tune... but for what it is, it can get the job done... the added benefits of the V.2 SAFC, in my mind, justify it IF you are not looking for ultimate power. running that set-up stock on a JDM ecu using the AFC to richen things up abit (JDM ecu's run A LOT of advance... while it would be better to back the timing off to avoid knock... running a little richer can have the same result) seems like a decent way to go to me. keep in mind that Turbo XS modeled there Dtec fuel computer off the SAFC... they made a butt-load of improvements... but the SAFC is the bench mark for piggy-back fuel control.

The PowerFC is basically a standalone plug-in ECU made by Apex'i. It's wildly popular on older EJ series engines in other countries as well as many other makes. It's a very commonly used ECU, but not so much on Subarus in the US.

ITC was Apexi's old ignition timing controller. They stopped making it some time ago.

Ah, well the PowerFC being a standalone is infinitely better than any piggyback. Too bad its not availiable for USDM cars or they don't offer a wire-in version.

I work in a tuning shop, and we really dislike the S-AFC for tuning because its so limited and it just seems like a waste of money when you could spend a little bit more for better solutions.

dude, whatever, USDM swapped L is still sweet!!... as far as the SAFC-2 it definitely gets the job done... I watched it fix the AF ratio on this car at the touch of a switch and there is 0 knock right now... When all is said and done, if this setup is working for the goals you want to meet, why spend more? Anyway, with all of the features installed in powerlab's car for engine monitering I would have no fear of running the SAFC-2. Also, to it's credit, I had a friend running the stock ecu and the original SAFC on his open class 1g talon rally car (granted that's a different car with a much more mod-friendly ECU) but the point is, there are lots of people that know what they're doing tuning with these... if it works, that's all that counts. ALSO the 12.61 that sam ran in the quartermile was with a bad launch, snow tires, a passenger and a full tank of gas... not to mention it was on the low boost setting (read 15psi instead of 20-22 psi on high boost... I think this car has the potential to run low 12's to high 11's as it sits... only time will tell

Give the kid a freaking break about the AFC...it works fine with a stock engine/ecu and it doesn't seem like he's breaking hte bounds of practical horsepower anyway. Very nice times and look though

Running an S-AFC in a DSM is just silly. You can chip their stock ECU just as easily as a Honda's, for free too.

I would have been running an afc in my jdm swap but the ecu rejects it. And I out grew it fast meaning it can only do so much. Oh, and it is known to pull timing badly.

Do you go to Tech, NMU or Lake State? I'm an old Tech alum that got sick of shoveling snow.

He's at Tech... as am I

I've already shoveled a few times this year... i'm happy about the whole having a garage thing though this year.

Nice work on the car, Sam... i also agree with Reid though... not so sure it's better than sex

Very nice looking car. I'd like to see some dyno numbers too.

Are you still on the stock RS 5-speed?
