Maf tuning issues

[SgtlesDavenport]

Thanks in advance to any help given.

I am absolutely new to tuning and trying to Maf tune my 2011 suburban 1500 E38 ecu.
I have watched several videos and spent a lot of time searching for an answer. Wile building the graph for the eq err I only have MafvsFrequency.
I don't have High or low. Is this what I am supposed to be using? Because it isn't working, I do have a wideband connected and everything disabled that is supposed to be.
Kinda lost and cant find the bread crumbs.

Thanks again.

A 2011 is only going to have one MAF table.

Not sure what I am doing wrong then. Here is my file.2011 suburban Maf step1.hpt

I believe you are looking for this...
In your Graphs Layout - Parameter, Parameter Selector - Maths, Choose Afr error OR EQ error depending on how you are logging.
Then in your column selection MAF(hz)... Copy the labels from your MAF table in your tune file and paste into the values

If your not sure what to log you can go to tools menu (top of scanner screen) Maths Open the one you want and it will tell you what it it logging for the predefined parameter

I have done that, just not getting any data in the table.

Then you might be missing something in the channels list.

Post up a log

I did, it is toward the top. Figured it out though. My WBO2 was displaying in AFR not lambda, took me a minute but I figured out what to do to change it.
Thanks for everyone's help. 100% positive will be back.

Having the same problem but I?m not using a wide band. Got channels reading but graphs will not work.

Simply check your graph details and ensure it matches your channels in which you are getting your data. If that is incorrect your graph wont have anything to show.
