code 13.....what can i do
 

I keep gettin code 13 each morning when i start my car. Is there any way to get rid of this?
It is on a 99 civic si with 440 injectors and a vafc hack.

i believe 13 is a faulty ecu, i could be wrong though....

13 is barometric pressure. I know because I get the same one, and so do a lot of people using the hack. I think you might keep it from appearing if you richen the fuel a little so the afc doesn't change the map signal so drastically. When I added fuel temporarily and cleared the ecu, mine went away. But it doesn't hurt anything, so I wouldn't worry about it too much. Just check the codes every once in awhile to make sure that is the only code there.
