The ECU will shoot for a particular A/F that you dictate no matter whether adaptive is on or not -- it's displayed as LAMBSE.

Turninng adaptive off only elimnates any compensation that computer would make from the O2 sensor feedback (ie. KAMRF long term fuel trims). For a street car, I would only turn off adaptive while tuning with a wideband. Otherwise, I would leave it on all the time.

Alright, I plan on doing all of my tuning with the tweecer. I wanted to shut off adaptive and force open loop, because I am absolutly terified of running lean when I'm in boost. It may never happen/not even be possible, but that is the way I understood things.
I am going to be running a Dynojet WB Commander permantly mounted in the car.
It is most definatly a daily driver. At least until I get a beater to roll around in and save it for nice days. Plan to take it the tracks a few times a year, but nothing crazy. My goal is to have a decent mannered, hot street car. Like I said, I was/am terrified of grenading my new motor.
I am going to try to do a base tune (idle, low rpm stuff) with the blower belt off, and then start working part and WOT.


So if I shut off adaptive while doing my tune, and then turn it back on, the eec will still try to shoot for what I put in the fuel tables, correct?

Thanks for the questions and the answers. All of it helps me get on the right track.

Yes.
