so a k/n drop in filter is enough to need a tune?

Can anyone please explain why the tq in this graph is so much lower than the tq the guy in this link makes if they are both stock 09 wrx's....

Subytek's car was dyno'd on a dynojet, one of the highest reading types of dynos out there. For about the 5 millionth time on this forum, dyno numbers between different dynos are not comparable. Even if two dynos are the same type, they can be calibrated to read different numbers. Total numbers are only comparable between cars on the same day and the same dyno.

The firmware update for this application should be out within two weeks, if not sooner. If you have purchase and AP-SUB-003, then you will need to update the firmware (only after we have made the firmware update available) before you try to install the device to your 2009 WRX MT vehicle.

We have started a thread on our forums to allow 2009 WRX MT owners to communicate directly with us about how their vehicles are performing.

Take care,
Christian.

Thanks because I ordered the AP from Harman Motive yesterday I would have received it today but no one was home to sign so fedex has to try again tomorrow

Surgeline AVO 380 tune and AVO 380 vs VF52

Posted on the Legacygt.com forum


"COBB tuning gurus, Tim Bailey of Surgeline Tuning and Sean Sexton of RalliTEK , has just finished up creating some official COBB baseline maps for an AVO Stage 3 kit. Creating an official map is a bit different than your run-of-the mill tune, as this is going to be used not only as a plug-and-play tuning map for Stage 3 kit owners, but is also likely the base starting point for many tuners looking to get to the bleeding edge of performance with this turbo. There is nothing half-assed about a COBB base map, with every parameter measured and every eventuality taken care of.



As you can imagine, it took a bit of work and fine-tuning to arrive at the best basemap for this setup. While the AVO380 is currently the "smallest" ball-bearing turbocharger made by AVO for the 08 WRX, 05+ Legacy, and 09 Forester, it is still quite a bit larger than the largest stock turbocharger Subaru has. Rated at 44lb of flow, it is quite a bit of a bump in performance when matched with the appropriate modifications.

Sean at Rallitek in Portland, Oregon has put together a stage 3 kit that combines a number of AVO components into a single potent package. It consists of a AVO turbo-back exhaust, TMIC, intake kit, hi-flow fuel pump, Deatschwerks 750cc injectors, and most importantly, an AVO380 turbocharger. All these upgrades are managed efficiently by a COBB AccessPORT, which is essential in pulling all of it together in one cohesive whole. The tuning was carried out on a Mustang Dyno, considered a heartbreaker my many in the tuning community.



All runs were done on 92 octane pump gas. Several back to back runs were done so as to get the best figures possible for a safe tune. While more power is certainly available, Cobb insists on keeping things safe as well. Despite that, at the end of the day we arrived at a health 314whp and 338ft/lbs of torque! Even a conservative correction factor puts that at 383hp at the crank - nice!

Furthermore, analysis of the multiple dynograph runs shows the horsepower peaking at the same point near redline. This indicates that the limiting factor is not the AVO380, but the TMIC. Because of the engine bay space available on these newer Subaru's, upgraded TMIC's can only be made so large. With an FMIC even more power would be available for abuse!

Tim and Sean also spent the time to find out the ultimate limits of a VF52 turbocharger from Subaru - the stock turbocharger available on the 09 WRX. This journal-bearing turbocharger helps the 09 WRX make more power than the 08 WRX, and has become a hot item for people looking for a bolt-in turbocharger upgrade for their Legacy or 08 WRX. Using the same setup as the AVO Stage 3 kit minus the AVO380, Tim and Sean ran out of turbo at 275whp. It did make power a little sooner than the larger AVO380, but by 3600rpm the AVO setup was pulling away quick. Peak power was reached by the VF52 at 5900rpm, whereas the AVO380 was still climbing at 6500rpm with no end in sight.

Everybody was very impressed with how the AVO380 performed. This basemap will soon be available officially through COBB and is going to be available through Rallitek as well, and should be bundled with new AccessPORTs as well. "

Very nice indeed, esp for a CA car. How is it as a daily driver?

I'm in Northern CA but my bro' lives in Fountain Valley. I"m going to have to stop in at HB speed next time I am there!!!

pretty much anything you change around the MAF is going to need a tune....

The MAF is simply a hot wire in the flow of the air.....when the air flows past it the temp decreases so the ecu increases the MAFv to the hot wire to maintain the temp. Our hot wire is only in a portion of the flow so the MAF is calibrated based on the stock intake diameter being 67.5 mm.

Therefore when you change the diameter of the piping you need to rescale the MAF (increase the g/s) to account for the extra air. The MAF sensor is still only measuring the same amount of air flowing over it since it just sits in the center of the tube....so you have to tell the ecu that there is more air flowing at the same MAFv to make the ecu add the proper amount of fuel.

Also, the diameter of the piping is not the only thing that can effect the reading of the mafv. Any sharp bends in the pipe before or after the MAF housing will change the way the air flows over the hot wire, therefore changing the MAFv.

The same can be said the filter thats utilized. The filters reduce/increase restrictions in the flow and thus change the way the air flows around the wire, thus just changing a filter can require a tune.

Per the above quotes and promise for more information:

First, my speculation about the WRX pump size was wrong. According to the parts list, the 09 WRX has the same fuel pump as the 08 WRX. Once I pull out one I will confirm. In tuning, our test car was at 100% duty cycle when we really pushed it, but then again so are stage 2 STIs. It is possible the down rating of the pump is higher then the actual difference.

None the less, if you have stage 2 and plan on pushing it, I say a Walbro pump is a good idea.

Just so everyone is on the same page, there are three part numbers related to the fuel pump.

42022D - The pump itself
42022 - The pump and white plastic bucket housing
42021 - The pump, white plastic bucket house, and fuel level float.

When the 08 STI first came out, you could only get the entire module with float. Now the pump itself can be ordered, but strangly for the 08 STI you still can't get the middle part (the pump and bucket, but no float).

Here are the numbers:

Fuel Pump by itself:
08/09 WRX 42022AG190
08/09 STI 42022FG060
05-09 Legacy 42022AG22A

Fuel Pump Module (wout float)
08-09 WRX 42022AG040
05-09 Legact 42022AG04A

Fuel Pump Module (w float)
08-09 WRX 42021AG040
08-09 STI 42021FG050
05-09 Legact 42021AG04A
