2020 civic si coupe error on dash

Post by blatered »

HI guys i just recently purchased hondata for my 2020 civic si coupe and im having problems with my tuner. after i load the tune errors on my dash board including cel would pop out on my dash. i tried reflashing (if thats the right word) it will be gone and it would come back again after a while. i dont know what to do. i've been reading in some forums and i tried whatever they say still doesnt work hope someone can help me.

Unfortunately if there is a single error Honda will display a long list of warnings on the dash (Emissions, Stability, Brakes etc) but will not actually tell you what the error was. So if this happens again connect the FlashPro and read the error by datalogging.

Install FlashProManager software
Connect the laptop to the FlashPro
Start the FlashProManager software
Switch on the ignition
Press F10 to start datalogging
Open the Error Codes window in FlashProManager

What modifications do you have to the vehicle? What calibration are you using?

boomba bov
Any BOV vents metered air and so makes the mixture very rich and there's your error code.

You should never use a BOV that vents to atmosphere on a vehicle with a AFM/MAF. Remove it.
