I've been installing an Innovate wideband afr gauge and an sii-4 unit which accepts 4 inputs. I've got it logging afr, rpm and tps on the triple Webers, with a knock sensor on the way.
This is all with the plan to road tune the Webers on the new motor coming soon.
I've found the Innovate products to be pretty easy to install and configure so far.
