Thread: fuel trim reset

  1. #1

    fuel trim reset

    I reconfigured my VE table and when I run the car I see the LFT's way high and causing the wideband to run very rich. I drove the car for 150 miles including 10 passes at the track. Should I wait longer for a automatic reset or manually reset the trims?

    You need to clear them before tuning the VE otherwise you are going to chase your tail
