[4cefedtiburon]

Ok I have about had it I have read through at least 4 diffrent ways to hook up the CAS input and heard at least 2 are no good. Is there someone out there that has made the modification and has done a good write up on how to do this? I have looked at DIyautotune.com and great write up but people say it dosnt work. Also others are incomplete as for if you need some things diy says or not. Basicaly WHERE CAN I GET A FULL WRITE UP THAT WORKS FOR SURE!!! Thank you. Forgot to add I currently have a MS1 with a V3 board and MSnse 2.25b514
