You apparently didn't read my response in the confusing second thread you hijacked. Then you appear to have deleted your posts in that thread, because now I can't find that thread. I told you I DO NOT download files from 3rd party sites. I also suggested in my response to your posts in that thread that YOU look at the O2 sensor readings, and tell me what they are doing. This has got to be a cooperatrive effort. I explained that I don't like eeHack, prefer Scan9495, and directed you to post #2 in this thread:

This is what happens all the time when I try to help someone.

 

Firstly, I apologize for the confusion. I don't know exactly how I ended up hyjacking the other thread, and I did my best to clean that up and put the info in here.

Secondly, I work in IT, and completely understand why you wouldn't want to risk looking at anyone's data on your own machine, No worries there. I was throwing it up in case anyone wanted to see it raw, instead of asking questions.

Now, in regards to your reply on the other post I accidentally hijacked, I haven't seen it. I now understand you prefer 9495 over EEHack, that's fine, I have it too, but I don't know it as well. I'll take the time and learn how to log with it, and will be back in touch when I do.

Wasn't ignoring anyone/anything or trying to hijack another post. (honestly don't know how I got onto that thread instead of this one) Always appreciative of anyone's input and knowledge.

I'll repeat the processes tomorrow with 9495 and if you are willing, I can even host a Zoom meeting at some point where I can share my laptop's screen, and look at the data 'live' from the capture file if you are game for that.

Again, apologies for the confusion between threads/posts, really don't know how I did that, and truly do appreciate the assistance. I'm headed back to your linked post above to review your post/suggestions and will proceed from there.

Thank you,

Brian

 

My goal here is to try and give people the information they need to become more self sufficient in using scan tools. Apparently most people don’t even want to look at the data. I received one person's first log, and all he had done was start logging, turned the key to “run” WITHOUT starting the engine, and let the log run for 85 minutes, until the car battery died. In another, guy sent me a log he claimed he made for a hard accel pull on the street. When I opened the file it was less than two seconds of idle with the car at rest. I can understand why someone might be put off after looking at an eeHack log… totally, unnecessarily complicated presentation.

I have published my guide to reading the data from sensors and the PCM, specifically for the LT1. That’s a good starting point. The link is in the thread referenced above.

I'm a retired engineer (BSME, MS, PE). But I still do consulting work. One of my services is classes on how to read complex technical drawings for building roads, bridges, underground utilities, site development, etc. These “students” are laborers who are being moved up to foreman positions, and need to know how to read and understand the plans. They generally have no real technical education, some never finished high school, and many are ESL. But I've managed to develop teaching methods that have been very successful. My former employer pays me to do this several times each year. I try to use these methods on this site.

 

i have been doing I.T. for over 27 yrs & electronics over 50 yrs.
You will never find Zoom (program) on any device i own, but i did have a zoom modem back in the 90's

 

Have you done anything with your injectors? I’ve been seeing a ton of topics where injectors on the market are not evenly flowing, or flat out don't flow at all.

1. If the injectors are new, did they come from a quality source and were they flow tested?
2. If they are old, have you cleaned them (recommend flow testing at a speed shop)

With the critical roll of the injectors in EFI, if the O2 sensors are providing data and you are having an issue getting a rich/lean condition nailed down, this is where I would start.

You can also get and idea by using an infrared temp gun per cylinder if you are running headers; variation of temps on the primaries would give you an idea of how bad fluctuations are for how each cylinder is running.
