When you start your car in the morning, how fast does it go to stoich ?? what injectors are you running ? What does your WB02 display in the mornings and on start up when the car is cold ??

Ive been starting my car in the morning, Ill see like 12s or 13 in the driveway, but rght when I start driving, at the first light down the street, Ill immediatly see 14s and 15s.

Although I'm N/A. Mine behaves identically to yours.

 

Mine is completly lean when i 1st start the car, its a problem i have though not normal. I start the car, car runs near high 13, but as soon as u even tap the gas it goes to super lean that it bogs. But!, as soon as the temp needle passes the C, the a/f is perfect and car revs fine.

 

I have stock injectors ATM.

Before I installed the SFMU, my A/F would hover between 14.5-14.7 immediately at startup. Hot/cold... doesn't matter.

After installing SFMU, my A/F hovers around 15.6-16.0. But, I anticipate I'll get it back down to 14.7 with a little more tuning/playing with the set and vacuum screws on the SFMU.
