I am assuming by map sensor you mean primary O2 sensor.
Those readings came from my datalogs in Kmanager and I found that Hondata stated that:
"The air/fuel ratio is calculated from the stock lambda sensor. Note that JDM, USA and some other vehicles have a semi-wide band sensor, with a range of approx 11.5:1 to 30:1 European spec vehicles utilize a narrow band sensor, with a range of 14.5 - 14.9:1."
Also in the instructional video here:

In it, near the end he states that he RSX O2 sensor is a wideband O2 sensor and a very accurate and fast one at that.
I know that when I was first setting up my nitrous I started with more fuel and the A/F readings were in the 10.x range and as I reduced the amount of fuel the A/F ratio came up. I know when I add a second stage it will be dyno tuned for saftey and accuracy.:thumbsup:
I figure with 93 octane and the cold air calibration loaded (based on 91 octane the best available in California) we would not have to reduce the timing as much but I figured that I would play it safe. As I stated before even with all the mods I have including the nitrous I have not had any knocks (again knock on wood). I may try to add back 1 degree of ignition the next time I make some runs and see if I get any knock. :noes: If not I may leave it there or remove another degree and try again etc.:ugh:
