LLY: Tune question

[WVRigrat05]

No log on attachment, just gibberish

looks like you may need to reupload it or do another log. make sure you save the log before disconnecting or closing out

okay let me try again

Edit I loaded and saved to my pc but what do I need to do to make it read right on the forum , issue is I've never logged or added one to a forum so I don't know what it looks like :bummed:


Does anyone know what I did wrong or is there a certain way ?

It won't work I give up , I think efi files aren't supported I could be wrong , anyway I took a snapshot off my phone hope this helps me

does this help at aLL i can email the file but cant load onto site says its not supported

Eh not really :rofl:

But if the desired fuel pressure isn't any higher than stock, it's probably why the FPRV hasnt kicked open yet.

You will need to change the extension to something like "txt" but it looks like you have already been doing that. On our end we change it back to "efi".

You can also screen shot the WOT run so we can see if the the fuel pressure holds

That's normal, if you turn the switch all the way down to position 1 it will say non DSP, which is your base tune. Tune position 2 will say DSP 1 etc..

i guess thats what im kinda getting at, how much power over stock am i even making . im not a tuner but u would think they would turn me up enough to atleast need to shim that valve , i mean seems like its pretty common right out the gate for most trucks . moral of the story blah blah i dont think im getting the max potential outta my tunes .my buddy same year truck but with a ppe tuner eats me i realize how that sounds i watched the graph in a different chart set up and its not getting the desired i guess ill take a cell phone video and post it ? since i cant get it figured out .also im new to this stuff its my first time lol so dont be bare with me if i say something stupid is because i dont know thats why im asking

 

[2004LB7]

Also, I don't see the "actual fuel pressure" pid. May want to add the before logging

 

[Parker_]

Found em never mind , lot to learn on these things

 

[Parker_]

wow finally figured it out, to post it here u have to take the .efi portion and name it.ctz so for u to view it u need to rename it .efi but atleast i got it here let me know if it works i did three data logs
to do that you go into control panel
then to file explorer options
then view and uncheck hide extensions for known file types apply and then rename file to .efi can someone let me know if it works on there end please

it looks like your CP3, for the most part, is holding pressure. there is a section of the run where it drops to about 144 mpa when commanded is 160 mpa. it does go back up though.

maybe do the same run with regulator valve currant or percent pid included so we can see if the CP3 is falling behind or if it is the ECM causing it

from where i sit, everything seems good. just curious way there is a few seconds of lower fuel pressure.

it was commanding about 23k PSI but actual it dropped down to 18k. then worked its way back up to 23K PSI.

Kind of like a soft fuel line is collapsing when the fuel pump is pulling max draw. Check the fuel line especially on the bends.

You don't have a lift pump, correct?
