first 5 mins, running rich?

Ive gone through the lists in tuner pro but nothing jumps out at me that may affect this condition.
Heres the deal, it seams as though my blms are set fairly close to 128 (mostly 130 at all points), but, my commute to work is 15 mins, and for the first "aprox 5 mins", my blms are hovering around 117.
My first thought was something to do w/ coming up to temp, nope, I can reach 195* in a couple mins and the blms are still at 117 for a while longer. Then just like that, the numbers start clicking up to 128 ish.
Im usually into closed loop before I even hit the road.
I finally got set up to log data (about an hr ago, yea me , so maybe ill see exactly when the change happens.

Any insight?

Re: first 5 mins, running rich?

Purge can do that. The canister gets full of fuel after a warm shut down, then, when it first opens, a lot of fuel comes out and the canister purges until it's near empty.

Not saying it's your problem, but it'd be my first guess. Purge can contain enough fuel concentration to turn off the injectors and still run in a severe case (and small engine), which is why it's on a ported source (to avoid that).
