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.

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...

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

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

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

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.

log file

here is the log, the idle did not hunt as much on that one.

I cleaned the IAC and the passage, neither were very dirty. it didn't seem to make much difference. I decided to try and replace it, the second log is with the new, it didn't seem to make any...

Throttle blades were cleaned when I had the upper intake off about a month ago, as was the MAF. I didn't pull the IAC, I will do that later today and run a new log to see if that clears up the idle....

here is the updated log. I was doing some compare files on the VE table and seeing some of the changes, starting to understand some of this I think. I am taking it that with smaller number...

forgot to add, currently when I come up to a stop the motor hunts up and down and stalled once, othertimes i was quick enough to give it a little fuel. fun with 3 pedals, lol

Good Morning,

thank you for explaining the VE. that would be my error, I really thought i had read and or saw that the secondary was not used for much of anything on the blackbox and to only...

here is the new log, did have more of a stumble at idle but not terrible.

here is the log file, it did not run as bad as I had expected with the MAF disabled. I tried to get as many data cells populated on the fuel trim side.

Thanks, I will load that one in the morning and get a log. I appreciate the help and am interested in learning the different things to watch for to make the proper adjustments.

Thank you for your help.

Here is an updated log with the HZ channel added. Looks like only one spot where the KR was up much. LTFT at light throttle are showing pulling a lot of fuel. A/F gauge...

Hello everyone,

I have new to the tuning world, but I have been a mechanic (more on the diesel side) for many years. I am hoping someone can give me a few pointers on my tune I have been playing...

Hello,

I recently decided to pick up a HP Tuner to start learning more on the fuel injection tuning side of things instead of relying on paying others for something I feel I can learn/teach...
