the emanage is basically the same as a S-AFC....it modifys the signal from the MAF and therefore changes the amount of fueling....
so it s a piggyback.....
and the greddy, apexi, hks all change the fuel only.....
i can get technical and explain how they change timing too...but that is REAL in depth, but for all practical purposes, they do not have a timing control.....
so, will I still need a MBC or EBC with the accessport?? I know that the UTEC obviously eliminates the need for one, but will the accessport eliminate the need or will I still have to get one?? thanks.
Well it eliminates the boost controller in that the different maps change the boost, but you can't like manually change the boost w/o changing the maps. At least until the StreetTuner comes out.
Ok I am thinking of ordering my AccessPORT this weekend. First question I have is if I install an intake run a 93 octane stage 1 map, will the Perrin Short ram intake mess up the ECU at all?
Also can I reflash the ecu to the acutal stock map so that when the dealer works on it, it will always reset to the stock ECU settings so it would be undetectable. Also if I flash the ECU to a stock map, can I run a realtime stage 1 93 octane map while I drive the car? Thanks
Here's COBB's official answers from their FAQ on their reflashes (accessport basically just lets you do the reflash so I'm pretty sure they are the same).
Q. I have XYZ intake, do you have a map for it?
A. We can do mapping for quite a few intakes that are predictable. We have maps for the original(black) APS, Injen, and most of the short ram hot air intakes. The Blitz is about the only short ram that is not predictable. The car may not be as smooth or might miss out on some power since we have to tune even more conservatively with most of the intakes, but it will be safe, and run better than the factory ECU. Also, let us know what specific intake you have. We have had people order the map for the APS intake when in reality they had other intakes. Needless to say the tune was far from optimal. So far the AEM is about the only intake we have seen that is not predictable. We could make a map for it that would make sure that the car runs rich rather than lean, but the benefits would be far less than that if the customer just removed the intake and used the factory unit. We even have to do that on the dyno for the AEM intake. Also, even if the intake is advertised as not needing correction, causing no errors, or factory specifications, let us know. This is not the case on the intakes that we have tuned that make this claim, they do require correction. Just because the piping that the sensor sits in is the exact factory spec does not mean that there is no turbulence to throw the sensor off. In the end if you want the smoothest running car use the factory air box. If you want the noise and slightly better spool-up, remove the silencer in the fenderwell and toss a panel filter in the stock air-box. On the stock turbo you will make the same power as you will with an aftermarket intake. If you have any questions or want to get the best map, your best bet is to give us the most information you can and let us choose the proper map for your combo.
Q. Can a dealer detect my AccessECU reflash?
A. With the tools currently available at Subaru dealerships, it is not possible for them to detect that the ECU has been modified. We own the same service tools used by all Subaru dealerships and have verified that their function is unaltered by the AccessECU. Therefore, you vehicle can be serviced by the dealership in the same way as a stock vehicle.
