What will happen if i do this?

what if i unpulg the safc ( just from the part where you seperate the chord) from my car and turn on the car? What are the effects of doing so? Can this be bad for my car? -Ray

Just run the injector pulse based off the factory fuel map. Why? Do you have larger injectors?

Simply unplugging the AFC doesn't work. The car will run, but in some half assed safe mode. Essentially the same thing as when you forget to plug in the MAS... You need to reconnect the airflow meter's signal wire that the AFC intercepts. This is covered in the AFC's instructions and on the sites like RRE that list thier own instructions. Most poeple put male/female spade type connectors on to make this easy to do on the side of the road, and I believe some are included with the AFC, but it's been a while.
