not much difren, emanage got bigger map only & can add extra injector & with some model, u can adjust the ignition with extra wires.
if for ur myvi(no vtec & turbo), u just tune the AFR only, so.. no matter which u using, almost the same.
u can just compare them with log in into their website.
i more prefer the neo coz i can change to 3 difren setting by just 1 click... hahaha.....
emanage, need to tune it on dyno machine of on the road which messy...
