It works fine for me. Right click on the top left most corner of the MAF table (top picture posted) and copy row axis labels. I think what you're doing is clicking on the "period" link from the MAF...

16 silverado is 2 credits, 17 - 18 silverado is 4 credits.

Here's the log file for the first MAF calibration using my wideband.

Can you guys tell me if I'm logging the correct PID's? Also, if my commanded AFR is 14.11, should my WB be reading close to...

Thanks for that NotSure! I’ll give it a go and post what I get.

Could you elaborate on the "zoom in on a section" part? I'm not that technically advanced yet. Lol!

I used the 04 up truck on my 18 Silverado and it worked great. Would the Camaro calculations work also?

Thanks for the feedback DGS. I do it that way already, just so I have the improved (hopefully) MAF calibration loaded and running while trying to improve on it again and so forth.

What I didn't...

Tried to upload again but, it's a no-go. They must be having problems with the site..?

Edit** Figured it out. My log file exceeds the upload limit. Lol!! It's 11Mb.

It won't let me upload for some reason..?

I did remove the factory O2 for this. I’ve done the MAF & VVE with the LTFT & STFT math already. I was wanting to see how far off or how much better i could do with the WB.

I disable long and...

Hi all,

Can I get verification that I'm headed in the right direction with regards to tuning my virtual VE table with my aem wideband?

I couldn't get anything to log when doing the AFR Err...

Any updates to this Joe?

I got it to work but I'm not sure if it's correct for logging my EQ Err vs VVE..?

My graph has RPM on the X axis and Pressure Ratio on the Y axis to give me the EQ...

I knew I forgot something. I need to remember to reset LTFT everytime. Ok, so if I disable the fuel trim learn in the scanner, does that mean I can ignore setting it in the editor?





I will...

**EDIT: New log posted below.

Hey all,

I just made my first attempt at calibrating my MAF with my AEM wide band. It seems way less complicated then using fuel trims.

Anyway, I was hoping the...

Thanks for confirming DGS.

I'm sorry to revive an old post, but since I use this a my go-to reference at times, ^^ This post had me question how I was doing it. So with this method posted, both 3d models for "Manifold Switch...

Good to know. I will tune with my WB and compare with fuel trims when I'm done.

Thanks 5FDP!

Is this afr error method more accurate than the fuel trim method?

Thanks for the input Ben!! I wasn't sure if tuning in OL for anything other than WOT was feasible.

Hi all,

I'm getting ready to start calibrating my VVE table using a wideband and I was curious if there were any extra steps to take if I wanted to use the factory pre-cat O2 bung to install my WB...

If i don't have a wideband, should my LTFT's be enabled and be apart of the equation for the calibration?

Thanks for the feedback dr.mike. Your suggestion is only IF i have a wideband, right?

Thank you for the input!

I don't have a wide band, but I have the LTFT disabled. So my airflow is being based off of the STFT's & MAF frequency, I hope this is correct?

Hi all,

So i made my first attempt at calibrating my MAF sensor and I would appreciate any feedback with the attached log.

Some questions I have are; 1. How long should the drive be without...

Thanks for the feedback. The first thing i did when I noticed the difference in the way these two trucks acted was read both files and compared them. I intend to copy and paste the different tables...
