First time data logging

[Duecepipes22]

Hey guys, I just did my first time data logging and I have no idea what most of this means (I'm slowly tring to learn but am not even considering my own programming at this point). I have a mild built TBI 350 that already has a custom burned chip in it but when I had the chip burned my fuel pump was weak and the pressure dropped from 12 to 9 psi under a load. I just put a vortec EP381 pump in it but thanks to autozones crappy rentals, I haven't been able to recheck my fuel pressure. I assumed that it would be running rich with the extra pressure and from what I understand about looking at the BLMs its very rich. I also noticed that my knock numbers are very high at idle but I don't know how thats possible. My TPS is also suspect to being bad, but could someone interpret these numbers for me? I have ever table that WinALDL offers saved to my computer so if you need more, let me know, but here are the BLMs and knock for now. Thanks!

Sorry, I just noticed that the format got all jacked up after it was posted. I hope its still legible.

Ain't trying to post tables in text fun?...I've had a royal fail or two lol.

Now we have you hooked up go get a copy of TunerPro RT, http://www.tunerpro.net/

The dashboard will be helpful, like winaldl. You do want to get to know the sensors normal parameters. Most is 0-5volt range. o2 is 0-1volt...

False knock is likely at idle.

[Duecepipes22]

Thanks for the reply! I actually just got TunerPro RT today but I can't get it connected. When I test the com port I am using, it says its ready and working but as soon as I hook it up to the truck it says it failed and when I try to connect, nothing happens. I started a whole other thread dedicated to that problem, but long story short, will the 12 pin OBD I USB/ALDL cable that I got for the WinALDL work with the TunerPro RT? So the "knock" at idle is nothing to worry about?

[Duecepipes22]

Would the false knock at idle be enough for the computer to retard my timing? Are there any fixes for it? I've got a stumbling/searching idle (which seemed to get better after replacing the IAC but not its back and worse now that I adjusted my TPS to .54 volts) and it seems like every time it stumbles, I get a knock count.

[1.721afr]

Yes, knock counts normally result in retard.

Yes, if you dig through your bin you will find knock settings that can be adjusted.

But find out what the knock is, if it's internal engine noise, that's not so good.

Look for stuff like loose exhaust, converter bolts ect.

Notice the knock is at 80ish KPA and 400 rpm, that like the the knock sensor picking up the noise of the starter.

It seems like there is a quick engine hiccup right before I get a knock count. Could it have anything to do with how pig rich is running, causing a misfire in one of the cylinders? It only hiccups while idling and as you can see thats the only time it "knocks." I almost think the quick engine jolt of the hiccup sets off the knock sensor. I also noticed that if I use the 10 ohm resistor on my ALDL cable for tuner pro my engine idles at about 1000-1100 rpms. For winaldl I don't get a BLM reading unless I don't use the resistor and when I take it out, it starts idling at its normal 500-750 rpm putter.
