Yes, I HIGHLY suggest for anyone wanting to try out the MS2, to read, read, and read up on it first. There are MANY layout and tuning changes from MS1 EXtra, and it is a learning curve. I'll try and help out with what i can, but i cant take the place of you guys doing your homework and learning what's already been documented and written up. Go to megasquirt.info, and read any link you can find about MS2.
