Default COBB AccessPORT Stage 1 + uppipe

I'm installing an uppipe this weekend and I'm wondering if I should reset the ECU (back to Stage 1 base map) after the install or not? The reason I ask is that I don't want to have to wait for the car to re-learn again for a week.

no need to do a reset for just adding an uppipe....the car will learn any new targets on its own anyways, but given that the UP is such a small mod...just leave it be.

Hey Matt,

Let us know what you think of the up-pipe mod after already being at Stage 1. The STi up-pipe is my next planned addition after going from stock to Stage 1 recently.

Will do. That's exactly the pipe I'm installing, too.

I'd reccomend a reset. You definetly dont have to though.

The ECU could take much longer to learn the new conditions if you just install and drive.

+1 for reset. it's a good habit to get into. just find some school zones to launch from/speed through, you'll be golden. maybe not so much with the school zones part though.

i don't think a reset is necessary because your ECU will relearn either way.
i've proclaimed myself vilege ideeit multiple times though, so yeah. btw, i run stage1 with gutted uppipe and all i can say is "what's lag???"

Do the Vishnu reset if you want to jack the ECU's advance multiplier back up quickly.

That's what I like to hear. Up-pie is getting very tempting. Although, I want the STi pipe rather than the gutting route.

i would have gotten the STi pipe but i bought the gutted one from some guy on here for $40 so i couldn't pass it up. UP should be tempting, it doesn't feel like a lot when its on but only because the turbo pulls so much easier nowadays compared to the Subaru rock and jolt and then pull. waaaaay more fun to drive.

I've got a gutted up and down pipe, makes a great difference. My friend has the same car as me without anything done to it and there is a huge difference.

Quick question though, after gutting the two cats the CEL is on (obviously, not cats=poor cat eficiency) does the accessport stage 2 program the computer to ignore the o2 sensors or would I still have to do the CEL fixes for the gutted pipes?

yes the AP defeats all codes associated with the rear 02 sensor, EGT sensor, and cat eff below threshold codes.

But you need an aftermarket downpipe.

The stage two map wasnt made fora gutted stocker, and the stocker has a restrictive backing plate.

Yoou could if you really wanted to but dont expect the worl wheny ou dont follow reccomendations from the vendor.

In case anyone is wondering, I postponed the install to this weekend because I couldn't get ahold of an UP gasket.

By restrictive backing plate you mean that it is best to go with a bellmouth style downpipe or what is the restrictive backing plate?

is that only when running stage2? I'm probably going to gut just my up for the time being, and continue to run stage 1... will the ap handle that?

Well, I got it in but the Y-hose underneath the intercooler wouldn't meet up with the turbo like it did factory, so I'm not trying to boost much until I get some Samco hoses to replace it with.

However though, the UP makes the car SO much easier to drive around town. There's actually power below 2K!
