man.. how do you think I got a controlled area network in a 07 Nissan seperated into datastreams so that I could introduce a non Nissan tach signal back into it... I DIDNT DO IT.. but someone I hired for the job did in about a week.

I love this hobby too and this is why I am in it... It gives satisfaction and financially provides a lot higher than you probably assume.; not to prove anything to anybody.
If I am not doing anything automotive related in 10 years I will be doing something where I can still have you as a fan somehow.
