other then nissan march 73mm pistons..
what other pistons can fit, plug and play into ej-ve..
problem now is piston cracked, now found yrv k3-vet brand new 72mm..
in case mechanic call say need to rebore, have to turun 73mm..
am i right to say the ecu can be accessed via a harness ?
if so, is there a computer program cheap/free and simple enough to use to access the ecu realtime info? can DIY?
