My stumble is gone around 150 miles so far. The thing I notice now is it seems to go rich like 10.5 or so when it used to stumble. Wish I could log with my 2.0. I think I am going to disable lean spool.

Working here! No code in 300 miles (enough to be triggered a couple of times).

Worked for me as well. Im at 800 miles and no code. Also on the bright side is that the P0300 test showed up as supported and complete for my emissions test. Thats the best part of all in my opinion.

I presently have "0001" in that location as per Lucas' suggestion. I believe it disables several emissions related subroutines as per my recollection. Is this correct?

Ted,

Yes it is. The fuel pressure overun code (P0090), Evap codes, EGR codes, and a few other pesky ones. I will post the whole list up later or PM it to you.

Is there a step by step how to on this? Getting into the ECU and changing things like this sends my brain in to retardation mode with the computer code etc... I have Jun 272s and on cold starts I have been getting this code alot since it got colder here. The colder it is the more my car hates life trying to warm up with these cams. And it results in a P0300 code

Changing the periphery bit 2 to EDCF disabled my egr test as well. The car just passed an obd2 smog check with it disabled. Just an fyi.
