Look at that perfect AFR

nice- i still need to put a boost sensor into mine.

I sure hope that's not your A/F ratio under boost.

My Vitesse AFR under heavy boost is 11.6

And even during normal driving (off- boost) My AFR is constantly fluctuating between 13.5 - 15. It only settles around 14.7 when i'm at consistant speed or idle.

I've never seen a strait line AFR.

edit: I'm pulling this data from a Zietronix as well. I'd check your O2 sensor wiring.

14.7:1 is retardedly lean. a good a/f ratio for a car under heavy boost is between 11 and 12, like jakery said. Granted im new to porsches, so maybe im missing something here, but that seems pretty dangerous.

I don't think the wideband or EGT is connected yet.

The O2 sensor and EGT probe are not installed yet

It's on my "to-do" list! I'll report back once that's done.
