have you guys ever done that? would it hurt? cuz i'm runing a 5spd ecu in my automatic car right now....it seems to work fine...no difference except the D4 is blinking.....i'm runing a 5spd ecu in an auto because i'm converting my car to a 5spd that's why i'm runing a 5spd ecu...

 

Cool if your not having any problems with your ride then i don't have to wait until i get the new trans. to put the ecu in.

 

noope it doesn't have any problems yet...it feel like it pulls harder in vtec
