Unplug the eccentric shaft sensor - what does it do?

I am not sure if the people who have aa tune had issues with their stock tune.

Can the stock tune adapt to the new headers air fuel mixture? I thought the aftermarket tune has something to do with that to make the car run well.

My indy told me that the idle problem maybe caused by the different locations of the pre cat o2 sensors as they are farther way than stock.

Been a while though I would re-chime in, yes on a stock tune with headers the car will run like shit thats why you get it tuned immediately.

Edit: also look at AFR's and fuel trims?

Sooner or later, that car was going to eat plastic. the stock tune will actuate the disas but not to full efficiency. the rough idle, sensor bank readings were caused by disa going bad.
