2012 chevy caprice vve and maf histogram issues

[moody876]

I just purchased my hp tuners mpvi2. I do not have a wideband currently. how can I get a histogram to work to try to log my tables for vve and maf error??

you can use your stft, ltft, or stft + ltft....pretty much just a preference. Don't need a wideband doing part throttle tuning

Thank you I got it working for the vve table %
What would I need for the maf tuning

Just need to set up your maf frequency table and log your the fuel trim(s) that you want to use...make sure to set the dynamic air rpm in the tune to a very low setting so you are running only on the maf
