    09 silverado calibrating maf

    well i am tuning my cousins 09 silverado i was just wondering if anybody had a histogram for maf. The stft & ltft don't work on this truck only has maf in the tune. One more quick question where can i find the table to adjust VE table. Hope to get some responses back Thank you.

    Resurrecting an old thread but hey, at least I used the search function!

    I am not showing LTFT or STFT in histograms on a 2008 Silverado w/5.3 and A4. First time fiddling with this truck and can't get these to log in the histogram. Sorry if this is an easy fix but I didn't find the info I was looking for via search.

    My histogram is setup with STFT as the sensor. For some reason, I had to also add this filter for it to work, if I don't, it doesn't work at all: [SENS.121] >12

    Sens.121 is your commanded air fuel.

    For Row & Col Axis, I'm using the Maf Airflow vs. Output Frequency which is a predefined table.

    open your histogram ---- then import histogram--- select these one i have attached ....

    make sure your primary display table have both long term fuel trim and short term fuel trim selected...

    as far as a ve table .. in these cars you may want to tune it MAF only ..if u still want to tune the VE then you need to use other software ( blue cat) or go custom operating system if its available for your car ...
