I think I started the "no 02 Sensor" stuff when I posted this quote from Hilborn a few days ago:"Along with not needing a laptop, our ECU does not require a MAP, MAF or O2 sensor. It is commonly referred to as an "Alpha N" computer. How can it possibly work without all those sensors you ask? When tuned, the ECU uses a maximum wide open throttle setting to identify the part throttle settings using TPS, coolant temp, RPM and acceleration inputs. We may not be as exact as a laptop to tune system, but we have given access to fuel injection for those who do not want to buy a laptop and learn complicated fuel maps, spend big dollars to hire a professional tuner, or have been waiting in the wings for the technology that we currently offer."
Guys thanks to all of you for posting on this topic I am learning a lot, and really enjoying the process. Dave
Even a speed density does not have to relly on an O2. The O2 is only for closed loop operation. From what you have said I still don't understand where it get's it's base fuel mapping from. Is there a way you can "tweak" it? It sounds like a computer controled set up where some one else can change the parameters but you can't.

What I interpret that as saying is that they (Hilborn) have written a fuel map for you.
Since you don't have a computer, or need a computer, you don't change it, or you simply can't change it.
Get the instructions first and look under the heading of changing the fuel script or map.
Maybe they give you a chip? (Yes that was a sarcastic remark, sorry I couldn't resist)
