Default Just went Stage 2 06 WRX

Hello,

Today, I installed my DP and Cobb Accessport with the OTS Stage 2 91 oct map.

However,
during the install of the accessport, the following message appeared
"this car has previously learned data, erase blah blah blah"

I just installed over it and put the Stage 2 map on my car.

When I bought this car, the stock heat shield for the turbo was missing and the AC line was moved to the side - which infers that the previous owner had a DP and the message from the accessport pretty much means that it had a non-stock map.

My question is...
Since there is a high possibility that the previous owner had a stage 2 map and the fact that i have been driving approximately 6 months with this map...

is there a chance that i might have done some damage to my car?

Thank you.

Only way to tell would be a compression and leak down test of each cylinder. That should tell you the condition of both the piston ringlands as well as the valves and timing position.

If the car is driving ok now, chances are there's nothing to worry about. If you're overly concerned then you might want to do what's mentioned above. How many miles are on the car?

The heatshield and AC drain link are definitely indicators that an aftermarket DP has been in play. But isn't there always learned data in the ECU unless you have a completely fresh reflash? I just assume that message is relating to things like the fine knock and AFR learning tables that typically get wiped on reflash?

Thanks you all for your input.

I bought the car at 70k and am currently at 77k. The car seems to drive fine, no weird noises, smooth, pulls decently.

I honestly have no idea.

1/2 1/2 situation for me.
In a way, kind of relieved, since I would rather have the previous owner have a tune with a DP than without.

The other 1/2 is if the tune that stayed on(whether it be no tune/stg 1/stg 2 will never know) damaged my car at all.

For now, Mike and Dartholomew's input has put me at ease.

If I start to get worried again, I will definitively go to a shop to get a compression test done. If it wasn't around 100 bucks, I would do it now but ...yeahhhhhh

Thanks again

Default NW Gas Mileage

Just curious, and slightly off topic, but what are you getting for mileage after the S2 tune with AP? Im from NW as well and have 06 STI I am considering getting the AP for, but I want to know if it will give me better mileage than the open sourced tune I'm working with now. Thanks for any word at all, and good luck with your compression issues...

I haven't been really been monitoring my gas mileage but i feel as if my gas mileage got worse. If anything I have been driving more conservatively because my coolant reservoir tank was broken.

I heard that it takes some time for the car to adapt to the new settings or something like that. I'm still new to this stuff. I've read that the stage 2 map should give you better gas mileage and the economy map should also but not by much compared to the stage 2 map.

hope this helps somewhat.
