Dyno Room Wide Band System
Yup these are expensive... BUT
Once you test per cylinder O2's your eyes will be opened.
This kit puts four controllers in one box, and is moderately portable. We have used them for track testing, on the engine dyno and the chassis dyno. The main goal of this was to put together a kit using what we feel are the best controllers on the market right now, and have a flexible usage window so they can be put to work in a few different areas.
One box has four controllers. It is too bulky to have 8 in one and remain portable.
One box = 4 cyl and start at $1325 with Bosch sensors, NTK sensors optional
