Scanner Readings

Ok cool, I will go do the test now, I wont be able to post that long of a graph, so I may have to do it in samples or have you remote into my scanner and see the whole graph.

Thanks!

If I did this right, here is what you want to see. This is a cat efficiency test.

Did the test but didn't show the sensors like I was expecting, will try to print them in sample unless you would rather see it live.

Thanks!
Dean

Live would be good.

    Here are the graphs, a total of 6 of them:
Bank#1
1: 2500 RPM No Propane
2: 2500 RPM With Propane
3: 2500 RPM Remove Propane at Marker 1.58
Bank #2 "Same As Above"


       

That would be GREAT
My Scanner has the option for a person to log into it. What would be the best time for you to log into my scanner, that way I can set what ever condition you want when looking at the graphs.

Thanks!
Dean

What is the process to log in? I can get to you in 20-30min.

20-30Min would be great for me! I will move my truck and warm it up, I can have my wife control the throttle if needed if we will add the propane again into the system.

What you do on your side is go to the following: "It's a secure site"
1: START.TEAMVIEWER.COM [It may ask you if it's ok to run there client utility]

2: I would give you my OBD reader ID number, then when I get the request it will ask me if you can take control I will answer yes, from there you have full control of my Autel Unit, Not sure if your familiar with their menu's, if not I can guild you thru them, there fairly simple and well laid out. You can call or text me as what you need me to do for the test while your watching it live

If you would like to set it up in advance we can do that as well so you can get familiar with the menus if needed.
.
I can PM you my cell number.

Thanks John!
Dean

 

Setting up laptop now. PM me at 9092731783 when you're ready.

Sent you a text from my texting number, not sure if you received it. But you can still cell on my Cell number I sent to you..(626)536-7XXX
Truck is warmed up and ready to go!

Thanks!
Dean

 

Dean,
After everything we did today I went back and read all your posts for anything I might have missed. I did, the P0430. That pretty much does it for me. I would call this a bad cat problem. But, careful, what caused the burnout. A rich condition for to long. If you decided to get a cat, check all readings after.
You could replace 02's but I don't think it's going solve the problem.

I was concentering that bank (2) had a bad Cat. but I didn't think that it would affect bank (1) readings to swing so wildly like they are on bank (2)
Assuming Cat (2) is bad would that cause it to miss really bad when going up a hill "Under a load" and cause a negative LTFT.

John, again thank you for today, you were very generous with your time and knowledge I very much appreciated it.

Dean,

It's been some time... We're you able to find a fix for the problem?

John

Hi John, unfortunately no I haven't I am still driving it every day to work, a few test I have done since we spoke I took to a smog test station and had them measure the exhaust and at first it showed very high "Bad readings" then as we put it on the Dyno and brought the RPM's for about 30 Sec's the reading came down to normal, I also recently drill (2) .200 in front of the CAT hoping that if there is too much pressure it would relive it and make it run normal but only seem to help it a small amount but not what I was hoping for, it seems that when I put a load on it the fuel trims don't really go up much at all, I am very frustrated with this issue but I won’t give up until I figure it out. Not sure what direction to go into next. I may need to put in bigger holes in the pipe to relieve more pressure however if you remember my pressure reading, they were showing more of an erratic reading mostly in the negative until I got the RPM up to about 3000.

If you have any other ideas, I would love to hear them...!

Have you checked for any timing issues. Distributor tight, gear wear, chain slack in cam Crank. Wondering if it's timing advance problem.
