Mike,

Judging from the ease with which you tuned out the= =20 staging bog, you have a pretty good handle on how to tune the engine with= the=20 EC-2/3.

For the benefit of the ones of us who are still tr= ying=20 to understand that tricky little gem, could you give us some kind of blow= by=20 blow as to how you went about tuning the bog out?=A0 I am wondering what= =20 you looked for to determine where the problem was and what you then did w= ith=20 trial and error? to tune it out.
