FiTech EFI system

I read somewhere that there's an updated flash to the handheld that is desirable if you are going to control timing. Does anyone have that update?

If you are not on the FB group, join it. There is so much good info there. I haven't purchased my unit yet, but I have been following the posts.

Is yours up and running or are you just getting setup? If so, how has it been working for you?
