Same question as above

I will take one, PM sent

I assume this is a CPI Injection 1991 4.3? Not TBI

Log and file

No one? I finally threw a PO171 and PO174 codes this weekend. I was out and didnt have laptop to log or read codes until this morning. I work shifts of 10hrs from 6am to 4:30, so after work was my...

SC or Turbo? What type fuel system and controller? What type of blow off or bypass valve?

Log 2 was a while back and prob before I started adjusting AFR/PE Ratio. Plus it may have been an off line WOT run.
Whereas Log 1 was recent, a 3rd gear start pull, with load (slight uphill getting...

Easier for me to just attach a few logs here.

This was where I got some KR on a 3rd gear pull onto interstate. I get KR around 4000

One is a simple WOT run form a while back

I can take a log real fast of it doing this. Just need to know what pids to log for best viewing

Noticed today that when I start up and idle, I get a steady 14.6 while it warms up. After it idles down to curb idle, it fluctuates. But within a normal range. According to the AEM WB digital gauge,...

I see. I will need to check that :) thx

I also heard someone say (and I see on a few custom tunes) that IAT Spark table needs smooting and takes away too much timing.

Hmm, so not having that tool I would assume not to do anyting with those? Or is there a certain direction to go. Mine is at 2.50 and below is my options. Unclear which direction the filter works....

Oh ok Joe, yes I only use one EXT PID, so thats my only free one :)

I got V1. Using it wired up analog is fine for me for now :)

I jst wanted to make sure in general I am doing this right when...

So lets say it is false knock from someting else......can one play with the Knock Filter settings or just change/reduce the Burst Knock or total KR setting?

So should the wideband be utilized on every log? Or are there some exceptions where WB Input are not warranted and deemed just taking space in the PIDs selection?

Oh snap..seriously :) haha I feel dumb :( But didnt buy it new and never read the entire instructions....just the install wiring part.
Yes I recall seeing the dial.

Ok yea mine too prettymuch....

I got my UEGO used so I only got the AFR Black faceplate...no Lambda faceplate. So as far as digital gauge is concerened, I can only use it as AFR.
Question since you have this gauge...how much back...

Yes I do and IIRC we went over them a while back and determined PLX was the same as AEM...AEM isnt listed in the EFILive unfortunately.
Attached the PDF Insturctions. Thx for looking over that for...

Oh ok.
Just since I have a wideband O2, I need to log 3-4 PIDS alone. Listed and questions below.
GM.EquivRatio = not sure why ?
EXT.AD1 - my AEM wideband white wire inputs to my V1 analog port...

I agree :)

For example, if I want to soley log AFR / PE during WOT, what are the PIDs that you would use to get most info and yet make it scan best by keeping them minimum?

Example for a Spark and KR log...

IIRC 2003 had it from the factory. Or am I mistaken?

Yea it could be just normal 4.3 noise. I recall hearing about it years ago. However dont recall what rpm its normal at.
I do know over the years they have done stuff to reduce noise in the 4.3 ...

Today I had some time, so I changed my AFR for e10 from what I was using 14.22 to 14.42. Thought maybe 14.2 was a bit rich and our gas is 'up to 10% eth' according to the stations. So stock was 14.68...
