Default AP Question

Hey guys, I have a 2004 wrx wagon. I'm currently running stage 2 with the AP. I have a Cobb sf intake and post maf hose, grimmspeed dp and an hks cat back. I just recently moved from socal to southern az. Emissions here is a tad bit different than Cali. I was wondering if I could unplug my AP and turning on my car to get it through emissions without any CELs. If I do so, am I running the risk of damaging the ECU?

If I understand your question, the AP does NOT need to be plugged into the car once a map is flashed.
So you flashed a stage 2, to go through inspection, unplug the AP and put it in your glove compartment. Get inspected, done.

No harm to the car.

Or are you asking if you can unmarry the AP with your mods and not cause damage?

The ap need not be plugged into the car 100% of the time. Hell I think mine was only ever plugged in for 3 minutes to flash a tune then went in the glove box.

Here in AZ (Tucson included, I used to live there) you just need to go in with no check engine light, and a gas cap... that's it. Doesn't matter if you are catless or whatever. leave the AP map on the car. hell, you could leave the AP on the dash and they won't care. Just leave the OBD2 plug open so they can plug in their tester. unplugging the AP does NOT affect the map - that's stored on the ECU.

welcome to the wlid west where anyone could be concealing a weapon without a need for a permit, and catless exhaust cars that run the streets unbothered by local environmentalist do-gooders.

Doesn't sound bad, really.

Same. I rarely plug it in the check DAM and maybe the AF learning numbers.

I don't even use it for autocross. I don't know how you people have time to look down at all these fancy numbers.

^ good post. I'm also a fan of getting a good trusted tune on the car, then keeping the AP in the glove box or at home. I do plug it in as you do every couple months to check AF values to make sure I dont have any intake leaks or obvious issues. Its not a good tool to keep in view if you have OCD tendencies and like to watch numbers move around as you drive....

Phatron Tuned

I think it depends on the type of tune. If you have a Pro Tune or a good E Tune then I don't think it's necessary to constantly watch the AP, but if you're running OTS I would think you'd want to make sure everything is ok considering how wide the variances in values can be on those maps.

With that being said, if you can't tune out the AP you probably won't enjoy the car. ESPECIALLY if you just look at the historical values lol

OTS tunes from Cobb are among the safest and some would argue safer than e-tunes. The problem is when people fail to read map notes and follow them.
