    Lost oil pressure after gear/tire wizard tune

    2011 Chevy Silverado 5.3 LC9

    Recently did the gear tire wizard tune on the truck and first drive out after I lost oil pressure. Went down to 6-7psi. Pulled over shut the car off. Luckily had my laptop and loaded the previous tune I had. Started the truck up and it was fine. Any ideas? I didn?t change anything else on the tune (unless my fat fingers clicked a button without me knowing). Should try and redo the gear tire wizard and see if happens again?

    Oil pump/pressure is purely mechanical outside of the tune. Don't see anyway tune can affect it.

    Did you accidently change anything in the Engine Diag > General section?
    A standard approach will give you standard results.

    I don?t believe so. Gonna go back thru it hopefully today or tomorrow and see if anything looks like was changed by accident. Maybe just something freak electrical with the oil pressure switch. Maybe a restart with or without reverted back to old tune would?ve fixed it. I might try to redo the gear/tire change again and see if same issue comes up.

    Did you have a warning or something that actually showed an actual low oil pressure?

    That's a little different than actually having low oil pressure. There may be settings that you can change for the levels that the message comes on.

    Have the screen plug up on the oil pressure sensor is super common on those trucks too, could always be that or a failing sensor.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    On occasions when I've flashed a tune on low battery, things would not work. Be it the temp gauge or speedometer, even the tach. I'd either drive it and charge battery and then reflash or put it on a charger, then reflash.
