Datamaster log, can anyone take a look?
Datamaster log, can anyone take a look?
Well, I loaded up and went to get a log today and forgot I didn't have freescan on the laptop anymore. i have datamaster and recorded a 5-10 minute log, which is saved as a *.uni file. Is there anyway to convert this information to a spreadsheet like freescan, or can I just host the uni file and have someone take a look at it and look for any abnormalities (under heavy throttle and at idle)?

Is the file, if anyone cares to take a look. Noticed the long term fuel trim are always pretty high... and notice at the end of the log, my RPMS surge between 400-600, (almost stalling out) while my oil pressure drops to probably 10-12 PSI.. just by looking at the gauge. Any indication as to what it could be. I guess I should throw out there that I've got a bum exhaust manifold gasket, a bum EGR gasket, and two EGR related vacuum leaks. All will be taken care of early next week when headers go on and EGR comes off.

I agree with vettedoctor, fix the mechanical problems first. Quick scan of you log shows you have low voltage 12.1-12.2 volts going down to 11.2 when your RPM dropped to 400-500. Also your right O2 sensor is not reacting the same as the left. It's putting out a lower voltage swing for both high and low range. Could be caused by the lower voltage effecting the O2 sensor heater, bad connector, dying sensor, etc. Your IAC also dropped down to 12 near the end (don't know why ?? ) most likely causing the RPM drop. 10 lbs of oil at 400 RPM is not abnormal for that RPM. 1- fix vacuum leaks, fix low voltage, recheck and possibly replace right O2 if it still reads weak voltages. R U throwing any codes ??

Heres some info on the code you have. It appears to be running extremely lean right now. Something wrong but its hard to say.

1) Turn off all your excess electrical (radio, fan, defrost, air,) then see how it runs
2) Unplug one of your 02's then see how it runs
If it runs good after #1 and you have decent voltage.. fix that
If it runs good after #2, then fix all your leaks. If you know you have all those leaks then why are you posting?

Because I didn't figure all of the problems were directly related to leaks. I wouldn't imagine that low voltage would be caused by leaks, and I wasn't sure what the drop in oil pressure had to do with leaks/rpm, then someone pointed out elsewhere that the oil pump is driven by the engine, which is directly related to the engine speed, which would cause those problems.
