Ok good trims. Moving to MAF

[Lostboy792]

here is the log, I forgot to ask if I should have been doing anything different with this part? so I just did the same basic route I have been.

[SiriusC1024]

You're still clearing LTFT and fuel trims before each log I hope.

I need more RPM. Try to get to redline a few times with 80% pedal. Lock it into 2nd if you have to. Also go for a longer drive 15-20 min. You're doing a good job varying loads and engine speeds. Just need more spread.

[Lostboy792]

Yes I am clearing LTFT before each log. also the truck is a manual, I can lock it in any gear, lol

[SiriusC1024]

Oh yeah lol duh.

[Lostboy792]

This should have the spread you are needing, got up around 42-4500 a couple of times in third gear.

[SiriusC1024]

Much better.

Alright hopefully this is the last one. May take one more though.

[Lostboy792]

didn't know if I still need some high rpm, so there are a couple in the mix.

[SiriusC1024]

Here's MAF 4.

Also, here's a tune setup to where you can take your trip. PE and DFCO is all that's different.

When you get back we can continue if you'd like.

I will let you know next week how it feels on the Full file and also will run a log on the MAF file. thank you for your help on this. I am looking forward to seeing how the truck does now that it is dialed in better.

[Lostboy792]

Just wanted to let you know it will be a bit for the next log. I am now having a fueling issue that started about halfway through the trip. Trying to narrow down what the problem is.
