They are a joke, dont join them. Someone asked a simple question about why is 04+ was loosing CAN Bus connection, I answered with 3 possible casues and why/fixes.

Someone with "4 years Auto Tech EXP" decided I was "A ****ing moron" and "The issue is 'too many devices plugged into the CAN Bus" and they switched to a 3 wire system in 05-08 so there isn't an issue anymore. LIKE ?!

First off your are aruing with someone who has A) Enough expierience in CAN Bus and VPW systems to tell you more than you ever needed to know, let alone the CAN Bus protocol is the same between all 04-08. Its standardized. Maybe they were having a problem with not enough throughput on the system but that isn't going to be caused by one thing plugged into the system that is scanning two pids.
B) An Electrical Engineer. Seriously.

Anger anger anger, Rant rant rant. morons morons morons.
