I have LT1 Edit and the PCM Comm program with it, but I haven't a clue what the values stand for on the PCM Comm data log.
I have uploaded a log from normal cruising to a WOT run and would like someone who knows the values to look at it or at least give me a website or some type of info where I can column these values to the respective places.
The problem is whenever I stop the idle drops to 500rpm. Sometimes it'll stall out, other times it'll studder for a few seconds and then recover. It has done this in the past and I found out the knock sensor was bad. Replaced it, ran great for several months and now it is back to doing the same thing. Whe I scanned it this time I discovered the knock was reading "0" the entire time whereas before it was pulling out around 12* of timing ever time the gas pedal was let off.
I also noticed my IAC "count" or "value" or whatever that stands for remained pretty constant throughout the runs. When the idle would dip down the "count/value" would drop a bit as well.
Here's the link to DL the file:

I tried to access your file, but it indicates it can only be downloaded once, and it has already been downloaded that one time. Appears to require signing up for some sort of "premium" service for multiple downloads.

If you can send me the file as an e-mail attachment, in ".xls" of ".csv" format, I'll take a look at it.

 

Fred,
You have to click on the "Free" icon and then enter some letters to ensure it's not a spam/automated user... yadda yadda yadda... I was trying to look for that page on your site, but obviously didn't look carefully enough.
I'm e-mailing the file now...
