No, the setting on emanage will NOT be gone after removing the battery or replace with new battery.
yup, JC Racing is a good place to inquire about emanage on 20v because i've personally seen a few 20v hooked up with emanage blue gaining at least 10whp easily, with ignition harness of cause.
dude, ppl asking about piggyback bro... not standalone. Microtech is nice but sadly limited to a particular car/engine only. Unlike other piggyback/standalone ecu, microtech cant be used with other types of car/engine than it was originally intended for.
