I have a 2020 civic EX with a K&N CAI. I put the base +3 tune on and I plan to have a dyno tune done with some additional parts installed late March or early April.
I was tuning the AFM for my CAI and my this is my first time tuning a car, but It seems pretty straight forward after looking at some guides provided by hondata and Google.
I did my 2nd tune to the AFM and my check engine light stayed on, and most my car features like ACC, Lane keep assist, Collision detection, etc all stopped working.
I went for a drive and after running the car to about 90 mph everything fixed itself except the check engine light.
Check engine light was resolved after I restart the car a few times.
I checked the diagnostics and the only errors were saying lost connection to network.
Any ideas?
It drives fine and runs a lot better after tuning the AFM.
Weird check engine light issue after tune.

Re: Weird check engine light issue after tune.
It it happens again use OBDII diagnostics -> diagnostics -> clear DTCs
