send it to the email in the button on this post, I'll try to get to it tonight. What symptoms are you seeing? (bog, backfire, stall, etc) and if they occurred during this run, do you know the rpm/speed it happened at? is this an auto or manual tranny? v6 or duke? any mods? I like to have the whole picture to help suggest anything.....

I Think Its A Timing Miss ..My Advance At 30 kmh Is 50 Degrees As You Will See When I Send The File
V6 Auto ..Mods 3.1 Stroker ..30 over powermax 2030 cam magnum roller tip rocker 1.6 msd coil ( not really a upgrade ) CRX Cold Air Intake
Just Feels Like back Fire ...Punch The Gas And You Dont Hear The Intake Suckin and Feels Like It Has No Power

do you have a more full run, like from startup up to parkway?
your clip of your run is very strange, I never see my timing held at 30 degrees advance like that, and I ahve a couple nice full runs in all conditions. I would say your base timing is whacked, but right at the very end, it drops to where it should be. the run you sent starts with a timing advance baseline around 30 degrees, and none of your other sensors show any indication of a reason to cause that. I am guessing this is a stock chip, not one of those aftermarket performance chips...... or a modified one..
if all that is stock, as in you opened the ecm and verified it is not a "performance" chip, I would think there is something very strange going on with your dist. when you las timed it, did you short the ab connectors on the aldl connector? tht could force the ecm to push the advance up all the time and cause no end of issues.....

ok, just had to check that. do you stil have the full file? there are some things missing in that file you sent, in particular, closed loop flag. It should have been in cl, as the temp was already up there, but I want to see it go closed loop, as that will also hold the timing more advanced.
while looking for things that cause closed loop, temp and o2 count being the 2 major players, your o2 is not switching very much, as in I would think you are getting some codes too, looks like a 13 is turning on there. you should be able to see codes in winaldl, check for what's posted. also be sure your check engine light is working. some codes take a while to lock the light on, you would see them as transient lights, it comes on for some time, then shuts off. The whole file should be small, send it along.
as I have been looking at other peoples logs, it really depends on the problem they are working on, so it really varies. basically for hints I look at: o2 sensor switching fairly regular in steady state rpms cts temp climbing and stabilizing closed loop flag coming on and staying on in steady state driving then look at map values following tps and rpm changes advance only for base levels, it varies alot in normal driving.
blm and int are fuel related, it depends on why that is being looked at. for a chip burn, or injector changes adding boost, etc, they are indicative of what needs to be tweaked. for a normal car, with no mods or minor mods they are usually a secondary indication, getting knocked out of whack by another problem.

Its Friggin Odd ..I Dont Get It ...I Can Drive It ..But It Just Doesnt Feel Right ...And When Im Done Driving It ..Come Home Put It In Park And It Just Dies ..
Timing Is Set To 10 Degress In Diag Mode ..>The Iac Clicks And All ..So I Know Its In There ... Checked To Make Sure Number One Was At TDC ..It Was
As For Errors Win Aldl Shows Not Errors It Had A O2 Error So I Replaced The O2 Sensor ..And It Cleared After Reseting The Ecm Did All The Timing Agian To Make Sure ..Perfect Timing ..Just Runs Crappy
Did A Vaccum Test ..Showed About 60-75
Its Got My Mind Whacked Soooooo Far Out ..I Dont Know What The Hell Im Doing Anymore ..Since Its My Daily Now It Really Got Me Going Crazy ....I Keep Tossing Money At It And It Just Laughs At Me
As Of Right Now I Would Trade This Gt For a Good Daily Driver ...And Thats Makin Me Very Sad
Another thought would be to check your damper has not slipped and the timing mark is off location. If it's off then your not setting it to 10 but something else all together.
If you need to know how to do that just ask. We'll give you some methods or there are many post of how to do it.

The Dampaner Better Not Have Slipped This Motor Was Put In Not To Long Ago ...The Car Ran Great Until I Replaced The Started And Dissconneted The Battery ...

his total timing is peaking around 50 intermittently, but only on the base point showing 30 degrees advanced. the log is not very complete, alot of sensor data is missing. it looks like open loop timing, the drops off to baseline 20 timing liek it would when it finally goes closed loop.
the little log he sent is no conclusive enough for me, it starts warmed up, short duration.
I would like to at least see the log form starting to turn off, all data logged.
I'll send it to you, you'll see what I mean....

Don't know what to think about the advance but I'm not to interested in that for now.
The engine is warm enough it should be in closed loop but is not.
The thing is there is no O2 reading so either there is a connector issue or the O2 is bad. The trash that is on the O2 is just that, a little noise which could be anything.
The BPW stays high but in open loop that is around the values you usually get.
Guess first thing I would do is see if you can get the O2 reading. Is it a new one or from an old engine?

the log did have the o2 code, but anyway, here is an easy thing: start the car, let it warm up. jumper the ab pins on the aldl connector. watch the check engine light, it should flash on. off regularly, about 1-2 secs in each mode, that is directly tied to o2 functioning.
you may want to doublecheck the connector from the o2 sensor, be sure it is fully seated and latched. if still no joy, you;re gonna have to meter the wire out to the ecm. or your new o2 sensor is bad....
