Yes, it has a MAP sensor and an O2 sensor... and of course RPM, timing, coolant temp, throttle position. I think fuel pressure is 45 psi. It also plugs to a laptop with a pretty neat tuning program. They provided a canned program for the Boss Hoss small block and suggested another program that is slightly more aggressive - available as a download on their web site. I haven't been able to drive it yet (building a whole new tank/fuel system again) but it revs really strong and doesn't stumble at all (like my Holley always did). Of course one can custom program - I think the approach is to go drive it for a few minutes, review the captured data and make adjustments where you wish to experiment. There are some 130 or so specific points of MP / RPM / fuel flow all of which can be adjusted. What I'm hoping for (and they think will happen) is a significantly reduced fuel flow at typical 60- 70 mph cruising conditions where the engine is really loafing. They predict, in general, considerably better economy and a little more power. From the stationary running that I've done so far, it seems to have a lot more spunk and so far, the pipes are not black inside as was the case with the Holley.
