Hi there,
I have a 2015 Sierra 5.3, and I just bought the MPVI2 and want to get started.
I?ve watched a number of YouTube videos, and the consensus is that I really need to use a wideband to get the most out of the tune.
I would like to use the tuner on my buddy?s truck as well, and so I am wondering if it is possible to only temporarily install the wideband in a factory O2 bung during logging and tuning. Then replace the factory sensor for normal use, I realize after every modification I would need to reinstall it to update the tune. I don?t particularly want to get a bung welded on, and as I said I want to be able to tune other vehicles.
If I go down this route, what steps would I need to take in order to tune? I?m assuming force Open Loop. Are there any SES/DTCs to disable? Do I leave the factory narrowband connected to its harness but loose, or should I remove it?
Many thanks!
Chris
