ECMlink Guidance on my tune

[DimShady]

Hey guys, I am currently working on my first tune. I had a fellow member doing it for me but he decided to get out of the game so here I am. I have been following a basic tune guide I for on the forums. I did a few tweeks to it tonight,I know its not perfect Any help and guidance is much appreciated.

1. What fuel?
2. Your MAF Comp sliders are all over the place. There shouldn't be that much variance between points.
3. I notice that at idle your AirflowPerRev is pretty low (.19-.20). This should be around .25.
4. Your fuel trims are out of whack. Hopefully going through
5. Get your wideband logged.
6. You might want to add some more values - http://www.dsmtuners.com/forums/ecmlink-tuning-log-file-advice/444831-list-values-log.html
7. Have you gone through everything in this guide yet? http://www.dsmtuners.com/forums/ecm...efore-you-ask-ecmlink-dsmlink-log-advice.html

I'm running 93 octane. That is the easiest to come by here. I have seen both of those links. I had all of the tests done, however I want to do another boost leak test this weekend since I have changed a few things from the last tune.

I'll add more values during my next logging session tomorrow. I was going off of a basic tuning guide I had found on the forums.

As for the wideband log, do I run the LC-1 WB? I do not recall seeing one for the MTX-L in the wideband section.

Thanks for info and the help

Ya, just run it as an LC-1. Pretty much the same thing.

Zeroed out my MAFsliders and logged more stuff. what canI do to fix the AirflowPerRev and idle and how can I fix the fuel trims?

Adjust the 50hz maf slider until airflowperrev is .25 and then use deadtime to bring combinedFT to 0%. Once combinedFT is 0% reset the fuel trims and ltft Lo and stft should end up around 0%

Check out all the items in the link I gave you above for item #7. One of them is a collection of videos put together by the guys at ECMTuning and will show you how to do this.
