I want to learn how to map ecu's but am currently unable to find anybody willing to teach and have heard nobody will teach me. Is this true or just a myth to stop me learning and taking over something only done by specialists?

i take it its true

The people doing mapping have years of experience.... the only way they might let you know is getting a job working for them ?

DunxC

well i have asked if i could go down and work with someone that does mapping but he said no and there arent many people that do it near me that i know do it well if you know what i mean

its not rocket science
