Cool beans! I'll adjust the bin and do some logging tomorrow! Going to run the stock ve table and get the BLMs close with the BPW setting and see what the heck that does for me.

I bet you dudes with emulators could tune my idle in about 20 minutes... Stupid lack of money and whatnot!

Yet even more for my personal referece pile. My list of scalers,
and list of tables.
and list of tables.

Emulators are very helpful. Yes, I own an Ostrich 2. I work on other vehicles to support my EFI addiction. It's not always easy for me to find the time to work on someone vehicle.

I hope it didnt sound like i was begging you to to help me with your emulator! I was just being envious having that ability!

I didn't think like that at all. I just wanted to say, I have to work a little extra to have some cool toys.

With the burn2 programmer and TP, can I read and import my stock chip? Of so, how do I go about it?

Alight so, this Tuesday the 20th is my birthday. So im taking the day off from mork and everything else and im going to do nothing but work on the truck all day! Going to start the day by double triple checking all the mechanical stuff like min air setting and timing. then im going to burn and burn and burn chips all day! Going to start with stock (combined) ve table, and stock timing. Then, im going to to get my idle blms close to 125-128 using my BPW. From there i will fine tune the ve table and add in some timing. From there, i have a hunch that i will be fairly close to where i am now but a little better off. I think that i will still have to adjust my open loop AFR and/or my R/L/M o2 threasholds, as well as my idle speed deadband. After all that, im really hoping that i will be back in business! So, on the 20th, expect many MANY questions! Its going to be both a frustrating and glorious day all at once. Pretty stoked tho to have gotten TP to read my data! Means i wont have to dick around with opening and closing winaldl to witch to tp and back again!

About the timing. I know one thing for sure, its messed up. I have been running my physical base timing (tss wire unplugged) anywhere between 0* to 12* advance and have never changed it in my chip. What effect would that have on my total timing? Say for example, i set the distributor at 8* advance, initial in bin at 0* and had my main SA set to like 25*. Would that put me at 33* advance? Now if i had dist at 0* and initial in bin at 0* and main SA at 25* i would have 25* right? So i guess my question is, what if any purpose would be served in advancing the distributor if its just going to coincide with the computer anyway? Leads my to believe that if you have it set at 0 at the dist, 0 in the comp and 25 in the table, its the same as 8 at the dist, 8 in the comp and 25 in the table. Am i way "off base" (get it!? PUN!) here or am i kinda right?

I think timing is a topic that is NOT easily answered in a post. The quick answer is to set the timing and computer to the factory specification.
Factory spec dist 0 ~ Chip spec 0 = 0 advance / retard
Dist +4 ~ Chip programmed 0 = +4 advance

And that's true across the whole table then right?

Note to self: If i get to the point of either desperation or curiosity and want try experimenting with the RLM o2 threasholds and AFR. I want to take all three values down thats DOWN 50-100mv. and then, for the AFR, i want to bump it into the 15.5:1 range at idle.

Also, if i want to idle in open loop, i think i want to play with the rpm below which open loop is allowed, and rpm above which open loop is forced off.

I have not experimented with RLM o2 threasholds.

Im not convinced that i have to. Just kinda something for me to play with if i reach that point. From here,

Lots of fun stuff in there about the o2s!

Went ahead and changed the settings. This $hits gunna be crazy! At this point im curious to see what all this wackyness does! Im sure enough that i changed everything enough to where it wont run, screw it. Its going to be fun to see what kind of difference it makes. I need a dang wide band and emulator!
