    Default Lean idle?

    Ok, what am i missing? Doing the VE Auto Tune thing and it's everything the motor can do to idle (WAY lean) on initial startup. It doesn't matter if it's hot or cold. For the first few seconds, about 10 or so, it runs way lean then almost appears to go into closed loop, but that isn't possible right now with the Auto VE settings. After those first few seconds, it idles fine. All settings are per Auto VE instructions.

    Muchos grassyass. I don't feel so bad now at least. I have to agree with you that i think there is a table in the PCM that we can't see/modify.

    Not sure if you fixed your problem already or if you have your AIR pump installed, but disabling my air pump fixed my actual wideband readings on cold start.
