Hello everyone.

So I use two ecus in my car; one stock and one that is tuned. I needed to get an ri state inspection sticker so I swapped my stick ecu in there to be safe. Unfortunately my car "failed" because it was unable to read any o the sensors, oxygen etc.
Not a big deal as they said to just drive the car for a few days and the sensors should be calibrated and they will give me a sticker.
My question is, how many miles are needed to get everything calibrated? I only drive 4 miles to work so I need to do some extra driving to get everything calibrated, just trying to figure out how many.

Thanks in advance!

 

do some city driving and take it for a drive on the freeway, its not the time its driven its how. the sensors are only tested under certain conditions, like load, speed, temperature.

 

Do a search on google for gm drive cycle it'll tell you what to do.
