NYS drivers with JB4 tune, question on passing inspection
Put car in accessory position:
Open JB4 app
Set to MAP 0
Turn off car
remove OBDII connector
let car sit for 5 minutes with key far away
Start car normally, drive to testing facility
Passed without issue.
Not sure if you have a visual inspection or not, with some good wire routing you could probably even sneak an installed JB4 though that since there's so much plastic in the engine bay. Otherwise, probably safer to uninstall completely for any kind of invasive visual inspection.
