Target idle.

If you have a heavy wire you can mount the distribution closer to firewall. Just fuse it near battery.

hmmmm.

That log looks great! How's it doing?

[jameslleary]

still good, but i noticed the blms went low during cruise. Still think the engine may be a little tired.

[EagleMark]

They are so close you need to watch INT. Tomorrow will be differant.

[EagleMark]

Ha! I was looking at your log instead of the one I'm working on! Is that the 17 bin? Untouched? If not send me one.

Did you do that log after power disconnect?

[jameslleary]

Yeah, That was 17...i have not touched it at all.

Hey Mark,
I have the small cap dizzy installed, and I got the proper latency settings from a stock ASDU...runs like dooky. Is there something Im missing? Will try to get a log asap, in the hospital right now with Momma and our new baby. Tried to find the post where you posted up your bin for your burb...couldnt find it. seems to be running pretty good for the time being on a stock Ca Calibration.

[EagleMark]

Congratulations on the new kid!

We lost a grandma sunday...

Latency settings would be the only difference, that does not make sense? But then nothing about your truck mad sense back then... base timing set the same?

I lost my bin in computer crash but can get it from the Suburban now it's back, been on loan to kid. I'll read it today.

[jameslleary]

Cool, Thanks!
Condolences to you and your family:(
There are some things coming to light about my burb while I have been in the hospital...lotsa time for deep thought. For example, when I installed the TPI back in 02, I had the 86 smogger heads that came on the GMgoodwrench engine. I also ran stand alone fuel lines, the return was a 3/8" that i ran to a 3/8 nipple that I had installed in the filler tube.
With the required dual cats, and AUJP, that baby passed smog like a champ...cleaner than most newer vehicles.
Fast forward to 2009.
Changed to TBI heads, the comp TBI/TPI cam....ran real good, more low end.
i swapped the fuel lines to using the 86 main and return lines on the frame. Return line on the truck is 1/4....pretty small compaired to what I had.
The idle got niticeably rougher, and the next smog barely passed, and after that, the cats just quit working....which made me swap to TBI.
Return line will be changed before the next 350 mile trip for thanksgiving.
Since installing the small cap dist, and using a stock bin, it has been running really good,,albeit a little on the rich side, according to my nose.
PROGRESS!

Fuel pressure would show an issue with return line. Still strange that chip should work with or without latency settings changed, correct latency would make spark more accurate.
