I figured out that i think my cord may be acting up or the odb2 port because it will be logging and all the sudden just stop. I can't figure out why because as soon as i hit the start button it starts up again. I did get an idle and rpm up to 3920 can't remember which stopped on me because it stopped on 3 or 4 occasions and one didn't get saved.
yes sir and i forgot to mention earlier that i have a throttle body spacer and the egr has been deleted. I had forgotten about the spacer until i checked the tranny fluid earlier. I think i lost 2nd gear sylinoid if it looks funky. It shifted fine all day then all the sudden it started skipping 2nd. I am going to play with it in a bit but figured i would send that and see if i needed another run or not.
Alright. Here I've applied changes and forecast the rest of the table. So far the fuel pump seems to be holding up. Higher RPM's again, please. Longer duration, too.
What I'd like to know is why LTFT's aren't working. Do you have an option for VCM Scanner>Vehicle Controls and Special Functions>Fuel & Spark>Fuel Trim Learn enable?
How thick is the spacer and what diameter is the opening? I'll add it to manifold volume. Not that it matters much, but hey.

I have that option but i didn't cut it off. I thought that was something that you had cut off when you started helping me. Is there anyway it could be turned off in scanner other than the controls option?
I didn't turn it off, in fact they haven't worked the whole time. I was hoping they'd update with enough driving. The tune is setup so that they are enabled. Try turning on that enable in scanner then disconnect.
This isn't the log you needed but i figured you would need to see what i done. I went to the options and cut on the LTFT and they didn't come on, i tried a few times and nothing. The last time i remember them working is before you started helping me and the only thing i could think of different was the channels on the left side. So i changed it to one i had and it went to working so i cleared it and went to logging. I couldn't make it shift to 2nd with options so ima look into that tommorow but what i noticed is the STFT is doing what it has been doing. May be a coincidence with the channels or may be actual issue, the whole time i been messing with it lately anything above 2.0 and below 60 in the tab STFT is always in the red. Is it the pump again or just me being paranoid?
i cleared the LTFT's before i ran the last tune. What was cutting them off? I didn't know changing the channels section did anything like that. I thought it just showed differant perameters.
I hope you remembered to clear LTFT's between tunes. Assuming you did, fuel trims go strongly positive after every deep decel and take a while to get back on track. It's like the fuel pressure regulator is sticking. Have you thought about replacing it?
I replaced it and the fuel rails about 2 months ago but thats not saying it isn't bad. I will replace it this afternoon and see what that does and i will get another log and clear them just to make sure.
Here is the log that i am sure i reset the fuel trims. I stopped and knew it wasn't enough so i did a 2nd also and numbered them in order. red 10.hpl red 11.hpl
