Default Has anyone tried the PerfectPower ECU yet?

I did a search and only came up with 3 results, so has anyone tried this yet? I'm looking for something to replace my S-AFC II since it really doesn't seem to do much for the MAP based Subaru (yes, color me wrong)

there are some posts on www.rallitek.net about this. They have had some decent success with it.

here is what the rallitek thread says:

Hey guys, we installed another PerfectPower today. This time is was a '00 RS that was basically stock. (Ganzflow intake box extension/axleback)

The car was running so rich (10.5:1 at the top end), if it ran any richer it wouldn't run! That tells me the mods done didn't flow any more air.

We installed a PerfectPower piggyback ecu and had the overfueling problem handled in about 2 hours. (Install / Tuning)

Those results are very different than the '04 RS we did a week or so ago. The '04 car had full bolt ons (Injen CAI/Borla Header/High flow cat/Full Catback) and was running very lean (14.2:1). Same test equipment installed in the same place(rear O2 sensor bung). So I am sure the results are accurate.

I need to continue installing these PerfectPower ECUs in different years/models on stock and modded cars so we know if the fueling differences come from the mods or if Subaru runs an '04 leaner than a '00.

With just bolt on mods and PerfectPower, RalliTEK made 126whp on a Mustang Dyno. Mustang dynos are notorious for reading low. The car has 48K miles, lightened pulley/flywheel, AEM intake, and TechWorks header/cat delete, and 5Zigen Catback. Here is the dyno sheet.

If only it controlled the revlimit...... Seems like a decent unit other than that one major function.

I'm just curious if you have to use premium gas like most chip require. The whole reason I got rid of my FXT and bought the TS was to save on gas.

Rev limit will require a standalone or a reflash. I have only heard of one re-flash. (Yoshi in Canada.)

PerfectPower has lots of features, but higher rev limit is not one of them.

Since it is a fully laptop programable engine management system(we use our PPs on WRX/STi/LGT...) You can set it up for 87, then switch maps and use 92. Or, go from 87 to race fuel or......
I can pre-program that kind of thing for you if you prefer.

Aside from the fuel and Timing control, RalliTEK PerfectPower features:

-Launch Control
-Boost Control
-Conditional Warning/Shift Light
-Has Air/Fuel Ratio Meter (NB)
-Simple to Use Windows Software
-Live data with Data Logger
-Overheat Protection
-Over Boost Protection

This is the full deal. The downside is it must be wired in. That is why we can offer is for such a great price. Wiring is fairly simple. I include wiring diagrams, instructions, and I am available by phone, IM, Email..... If you have any install trouble.

Check out the latest at www.rallitek.net in our RalliTEK PerfectPower Forums.

Would this system help with lame CELs from bolt ons? More specifically the P0402(did I get the number right?) the cat inefficient one. Thanks.

PerfectPower can't help with the Cat P0420 code. It can help other codes, like running lean, or rich....

You guys plan on having other shops install this device, such as Rallispec, etc? I'd be interested in trying something like this on an older modelled subaru. It's not a plug and plag device anyways so.....

Nope, but piggybacking a 2.2ohm resistor in the place of the O2 sensor plug will

2.2k ohm I believe. Im aware of the fixes for that code, waiting to have time to try the mechanical fix actually. Just curious if the system would help.

We're running the Rallitek PerfectPower Piggyback on the 2005 Subiesport Zero-to-Hero 2.5RS Project car--Rallitek is one of the project sponsors. It is my understanding that they will be making the maps we build off the ZtH car available to their customers.

We just finished up a tuning session with bolt-ons (header, intake, exhaust) and are adding COBB Spicy Cams next week. Full results should appear in the October 05 issue of Subiesport Magazine...right now we're still sifting through the data from the frist dyno runs and wont get the second in (with cams) for a few more weeks.

I think short of a reflash, this is quite a good deal - I haven't used it but this is almost like an eManage. My Link doesn't have all the features I need for a good stock tune and reflashes from i-Speed is still quite a ways away. Didn't really feel like dropping my Link and swing for a PP and redo all the wiring

Very cool, I'm going to replace my Apex'i S-AFC 2 very soon with a Perfect Power. I'm curious to see what my car will do after adding a few more parts then the P.P.

Next in Line: 4 into 1 headers, 2.25" custom catback into an 05 WRX muffler, Mr. Josh Pulley then comes the perfect power.

Currently: K&N Panel filter, Homemade 3" intake piping, S-AFC 2 (useless on an MAF'ed car) Random Tech Hi-flow into 2.25" catback with 03 WRX muffler.

If I can make 200 at the crank, I'll be happy.

Good luck on your quest for 200 - it's hard man, even at the crank. Technology is not on our side when it comes to the EJs

Are you sure it is worthless on a MAF car. I think it works on the MAF cars but is useless on the MAP cars.

Yup, thats what I meant, I've had to explain it to newbies so many times my head is starting to spin.

It sucks we can't make 200 easily on a 2.5 liter, Honda can make a 2.0 make 245HP in the S2000 and it gets better gas mileage!

Ah well, any gains without going turbo or mesing with internals are good ones. Maybe there will be some hope with the new 2.5 coming out next year, direct injection seems to boost the power to about 175HP... better then nothing.

A very peaky 200hp, with little relative torque (I used to have a '98 Integra 1.8L GSR that had a fair bit of mods on it.)
