i've been looking for something similar in the forums but couldn't find any...
well i got a gsr block with jdm p30 pistons
b16 head with either gsr cams or bc4 (obviously going to run the bc4 down the road)

now i need to know which ecu should i use to break it in?
or should i get a chipped ecu? (breaking in motor with chipped ecu safe?)


thanks...
