Thanks Matt.
Here is the MT MSQ file & I exported the VE table also. (somehow I cannot send to your email at attbi.com, it keep failing)

***I just did some changes to the tuning this morning 8/6/06***
http://www.geocities.com/gilee_8/eclipse/MainSetupNew.txt (Change .txt to .msq)

My Setup Details are:
680cc fuel injector, Static Fuel Pressure is 34.8PSI, idling fuel Pressure (without vaccum plugged) is around 43.5PSI, I am running fuel only, and the injectors are Low Impedence. Using Narrow Band O2 sensor right now, and with a 2.5Bar MAP sensor right now. I have the MS v3.0 board with MS-I chip.

I also include two logs that I just ran after I waited 6 hrs today after running today at noon time. Remember I said, after the car died, I cannot start up the engine again. so I have to wait.

Tonite, I did some more tuning, and it runs better I believe. And things look pretty good, but somehow to me it seems like when the car is fully warmup, it kick into another mode, (like using the VE table or something) So as soon as the Coolant temp get over like 160 or 170F, the car seems to run like shit. so I just start going into the VE Table, and start change the highlighted number to make the car stay running. So it is kinda rough at idle after warmup. Then after I shut it off, it own't start up again.

And from the log, I see the coolant temp goes to like 200F after engine is sat there for about 15 mins after it's off (after full warm up)
So I am thinking, does the coolant temp has to do with the problem not able to restart? like the amount of fuel injected?

I included the two logs, one is during the Running time after warmup, it shows how rough RPM is, then I try to change the values in the VE table to make it stable again.

The other log is after I turn off the engine and try to restart it again after 3-5 mins, and I crank it a few times, but with no luck!

Thanks again Matt. Let me know what you think of my setting.
I greatly appreicated your help.
Gilbert

P.S. I read from other post, and from what you mentioned before, that I should make the EGO (O2 sensor) not in closed loop right?
So where can I set it to not closed loop? I looked through all the options in MT but I don't see where I can change it to open loop.
The only option that I believe it can do so is the EGO option under Basic setting, do I just set the active RPM to like 6000 or something very high, so the EGO will not do any fuel correction until I hit 6000RPM, so it is kinda like turned off? Thanks again.

*** 8/6/06 Update ***
I just went out to do some changes all over my MegaTune, and I got a long log, but I cut and paste a part I believe it's important.
To me, it seems like once the Coolant Temp get to 180+F, the O2 sensor signal or the AFR get really rich.. like 0.9 for 30 second. The rest of the log for about 650sec, the O2 signal stay to bounce around (NBo2) but once 180+F, it stay constant at 0.9 and up to 1.xx, then the car choked and die after 30 second.

Here is the entire Log if you want to take a look:
http://www.geocities.com/gilee_8/eclipse/Die_After_180F.xls (right click and save as)

Take a look at the log. This is what I suspect maybe some setting I have is wrong, so once the Coolant temp get to a certain temperature, the AFR get all messed up?? car ran idling for over 10 mins.
