Oh I will buddy ........ I am sure there will be more questions from me LOL !!

and if I can help someone else out......... I would love to

 

Great...but long, thread! Amazing, your tenacity with Big Dirty!

Now that some time has passed since you chased off that stumble, was that indeed, the long term fix?

 

I seen this pop back up Dave I think we need to check on Benny Benny you OK Man

 

Still running good? What a thread!

 

spikedog .......... still "not" running good.

I mean it will still get up and go, but I still have the studder (or) bucking.

---- at idle in driveway ----

ECT = 186
EOT = 191
EBP = 16.8


was talking with Benny (aka:Blade) in pm's and I think I have replaced all of the sensors that would contribute to a bucking issue ........ all except the EBP sensor. I remember just cleaning the tube and the sensor and re-installing it.

the other night I was researching and came acorss a thread that mentioned the EBP and how it would contribute to a bucking issue.

I just purchased a new EBP sensor for $97 today. I took the 6.0 back home and pulled battery cables on both batteries and have the positive & negative cables tied together.

Drove the rock crawler back to work. When I get home I will replace it and if I have time I will take it for a test drive and report back the results.

Replaced the EBP sensor yesterday......... and from what I have read..... the EBP & MAP need to be .5 (+/-) from each other. Something g is out of whack.<br/><br/>btw..... I am on the SCT performance tune <br/>

 

This is at 55mph<br/><br/>With the SCT performance tune

 

have you put it back to stock? I would try to reload the stock tune run it for a bit and then reload the SCT tune. maybe it is not reading one of the sensors correctly.

 

doing that right now ......

at lunch ........ cleared the KAM then I dumped the stock tune back on the truck

just disconnected the batteries and turned the headlights on........

getting ready to go out and hook everything back up and do the KOEO VGT relearn......... then take it for a spin.

 

Well, people are curious, 35,000+ hits on this thread! you are not alone!

 

I know right ..... never expected that


Maybe I'm the gunie pig


Here is a question I have not been able to find an answer on:

EGR cooler Bypassed ...... Turned off EGR using SCT tuner ...

EGR plugged in ..... and left installed


if the EGR valve is bad will it still create issues?

 

It might rabbit,it might

 

sooooo 100% ........ absolutely

in the conditions stated above .......... if the EGR Valve is bad it could cause my bucking issue?

if it would I will buy another one

 

Well, that's a real good question and one that I have pondered in the past. While I really don't know for sure I would offer my thoughts.

The PCM determines how to fuel the engine based on EGR flow among other parameters. I don't know exactly how the tune "turns off" the EGR. I have always thought that the tune simple gives the PCM whatever it's looking for from the EGR valve. Now I am thinking that it's written into the program, or more specifically the EGR function is not written into the program.

I think you can determine this by looking at some of the EGR values on the SG2.

I also have a tune from an SCT tuner written by Innovative Diesel. I am gonna try and get some of the EGR values from the SG2 to see what they are.
