I logged my 92 Eclipse GSX a few days ago. Below are my results. Remember, this car is stock. if you see anything that looks incorrect for a stock car, please say something.
I've also attached 3 pictures showing some of my datalogging results. PLease comment on these as well.

Coolant 203 degrees and 0.43V

Battery 14.9V

Engine Speed 1000 RPM

Barometer 1.00 bar and 3.98V

Injector Pulse Width 1.79 2.05 ms

Air Temperature 96 degrees and 1.97V

Is this at idle or are you holding the vehicle @ 1000 Rpms?

PhoenixRPR · Jun 27, 2004

I have my idle set to 1000. This is because if I use the a/c, as you can see in the graphs, my idle will bog down quite a bit, so running at spec 750 isn't sufficient.

PhoenixRPR · Jun 27, 2004

Also note that the 2nd graph that shows the rpms dropping to 0 when i first engaged the a/c is not a mistake. My car really did stall because even at 1000 rpms it wasn't able to handle the load.

I invested in this datalogger so that I could give my fellows tuners, as well as myself, a visual of my car's outputs. I'd love to have some valuable feedback. Thanks.

yeah my O2 is all over the place to. but what does it mean when your air volume does not move i logged for a 26min drive.

PhoenixRPR · Jul 20, 2004

Well, it will log my EGT temperature and it doesn't move because I don't have an EGT probe so it just flatlines at 0 (useless). Perhaps this is the same case with the air volume line? Anyone else more knowledgeable able to confirm this?

JrCRXHF · Jul 20, 2004

i would think the air volume would be the MAF sensor

PhoenixRPR · Jul 21, 2004

Me too, but as you see in my graphs above, I don't show any readings above zero for the air volume. Post your datalogger snapshots so we can compare.

Question: In my 3rd graph above, at idle, the timing advance shows to be 14 degrees. Shouldn't it be 5 degrees? How come nobody pointed this out?

PhoenixRPR · Aug 3, 2004

Please, some feedback guys. That's why I logged the car and posted the screenshots.
