Hi, I have a 67 turbo beetle that has a MS2 V3. I am using boost control, edis, and an output to control my cooling fan. I too have helped in the installation of several MS's. 2 beetles, 1 Splitty bus, 1 Bay double cab, and currently working on a Chevy 4.3l v6 for my father in law.
A few things I am working on is logging Fuel pressure, Egt and my turbo back pressure. This will happen when I get my GPIO which is on order from DIY.
I am here to help.
