hondata - long term O2 adjustment
I’ve made some modifications to the exhaust this week and just did a run with the car while recording in HondaLogger. The long term adjustment was around -10. Does that mean, on average, I’m running 10% too rich or too lean? Is it a good idea to decrease (or increase?) all of my fuel numbers by 10% in the ROM Editor?

just run it open loop. i have 2 chips one open one closed and the open runs so much better at low rpms as long as its tuned well. i think i save gas in closed loop though but it sputters at times and chokes around town driving

Re: hondata - long term O2 adjustment (GruvyTune)
Open loop being the one that doesn't use the o2 sensor at all, and just reads the fuel table directly? I don't have mine tuned yet so I don't think I should do that. Once I get my f-max kit on I plan to make the drive to a hondata dealer to get everything tuned correctly.
