I just did a couple preliminary datalogs after getting it all set up. Would anyone be willing to look at them and point out problems? Also, could someone point me to information on how to go over my own logs? I don't want to be asking for help every time I need a log read and would like to do it myself, but right now it all makes sense, but I don't know what's good or bad for each line of info. These are tuner pro log files in a zip file. 2 files. Hopefully I actually did it right too.

First is from the on position to starting and running for a bit. Second was just a short running of the motor. This is for a 91 Trans Am.

 

I've been attempting to go over certain parts of the datalog, but not having much success. However, after reading a bit, I am concerned about a couple things. One, the ALDL flags. Seems almost every flag in switch 24 is throwing up a code in the log. However, they all say OK, so I have no clue what all that means. Also, if it IS a problem, I'm not seeing an SES light. The last time the SES light came on was a code 32 some time back. After replacing the EGR solenoid and the EGR valve(which was actually is lousy shape in my opinion) it hasn't come on since and doesn't seem to be listed in the codes, which I assume is a good sign.

Next, after reading the TPS/IAC tech articles and noticing a line about stumbling/driveability problems if the TPS voltage doesn't remain steady increase up to WOT, it got me thinking. Some of the time, the car stumbles a bit, I THINK only after it's warmed up but I could be wrong. Seems to happen more after it hits 2nd gear, but once you let off the throttle, meaning I'm cruising now or just slowly speeding up, the stumble isn't there, or so it seems. It doesn't happen at all RPMs/speed/etc Only seems prevalent when I'm into 2nd gear and giving it a good amount of gas to speed up. This is before and after my new tranny was installed, so that shouldn't be an issue. The TPS does seem to be a bit high? at about .59-.61 volts at idle which is off from the suggested .54 volts.

I haven't done a test of the TPS up to WOT to see if the volt increases steadily since I wanted to get a rundown from people here on my initial datalog so I have a better idea what to look for when I do a 2nd datalog. So, can anyone help me out please?

 

Can anyone help? Or point me to someone or some place that can have a look at the log?

 

I don't see anything wrong in them. No codes showing, fuel You'll need to drive the car to see more.
Idle in park doesn't allow you to see any hesitation issues. Need to log while the problem occurs.
Go for a nice 1/2 hour drive and run through many operating ranges from cold startup idle to romping on it a bit to get a good look at what is going on with fuel and spark with loads changing.

 

Excellent, I'll do that this weekend. I need to locate the stumbling problem so hopefully it will show up in the logs. Thanks for having a look at them, I greatly appreciate it!
