2017 chevy fuel trims
What happened to the adjustment for the fuel trims on the 2017 chevy Silverado 5.3. Got it on the 2008 gmc siera that im able to adjust but the 2017 Silverado dosent have that option. Whap happened to it and can this be added in a future update.
Re: 2017 chevy fuel trims
you can't do it man... 2014+ GM vehicles are direct-injection, totally different than old vehicles... you can not adjust the "injector slope" anymore like on older vehicles...
You would need to get a custom tune done in order to have the MAF Sensor table re-scaled, in order to adjust the airflow/fueling to get the fuel-trims inline where they should be... Which has always been the proper way to do it anyway, even on the older vehicles...
You should NOT adjust the injector slope setting at all, on any vehicle, unless you actually installed/changed to different fuel injectors from stock....
