Pulling timing via maf..What OS? I think I remember reading certain OS's allow you to pull timing via the maf readings. This would be great for a dry shot. What OS's allow this?
I have HP Tuners, does their MAF Real Time Tuning OS allow this?

Never heard of anyone doing it off the MAF. Many have used some type of IAT resistor (temperature tricking device) to indicate a temperature that would result in pulling timing from the IAT Timing table.

The MAF gives you the cylinder air value pretty cleanly
with an air density step (N2O raises density and drops
temperature). The speed density mode only can see the
temperature via IAT and that aspect of the tune is not
too solid, and the IAT not very fast.
All you have to do is see the cylinder air mass values
that separates natural from N2O operation and edit the
timing tables for the fatter situation. Of course if you
want fueling too then you have to inform it and/or
trick it.
