Love the ingenuity, but I have a couple of questions.
(Note that I am not an expert, but since I am running TBI with the 1227747 ECM on an engine that GM never made with the 1227747 and TBI combo, I had similar issues with finding the lowest, smoothest idle speed.)
In a thread you started about "setting up your tbi", you stated that you had set up the timing per the manual provided with the harness.
Where did that manual tell you to set the timing?

What I am curious about is that if you are running a pretty much stock engine with it's matching ECM and sensors, did the base timing adjustment in the painless manual match up with the base timing value programmed into the BIN file?
Unless I missed something in your posts, I did not see anything that indicated to what value you set the base timing at.
Also, in regards to the "open mode idle in drive" , my engine does that, and, seems to idle better, although I don't recall what all controls that. I do remember that it seems that in general, slightly rich at idle is what you want, but don't recall if that is idle park, or idle in drive.
If I am out of line asking any of the above, please let me know.
