Nitrous Oxide - Verifying the dry shot is working??

hi all, couple of quick questions concerning the dry shot..???
here's a breakdown. dual nozzles, spraying before the maf current jetting of 2x .033's. (for testing purposes)
i have HPtuners (logging capabilites only). S/C c5 6lbs boost.
when i activate the nitrous what should i see while logging at WOT?
what changes should i see while its on?
example of items being logged:
1) Inj duty cycle:
2) map:
3) WB:
4) KR:
5) RPM:
6) LTft's:
7) STft's:
8) Timing:
9) narrow band o2's:

i can go wot and log w/o the giggle juice on to get a baseline that the WB shows to be about 11.2afr, but when i hit the spray what should i see differences in/on with the items that are currently being logged./???

example:
1) duty cycle should increase? (%?)
2) map + or -?
3) WB max safe afr? (remember under a boost situation 6lbs)
4) hopefully zero
6) changes? if working correctly???
7) same as 6
8) same as 6
9) ?????

any and all help is greatly appreciated
thanks a bunch,

The easiest way to tell is to log your AIT's, you'll see them get colder. Of course your a/f will likely change and duty cycle will increase.
Your ltft and stft are out of the pic at wot, unless you have ltft that are postive, then they are froze at wot and added to your wot PE multiplier for a slightly richer wot a/f (neg ltft are dropped).

thanks robert. got any idea on how far the IDC will increase?

i did see the wb reading go from 11.2 to 11.8-12 during a 10sec pass.

Well that depends on shot size and nozzle location. Nozzle location can have an effect on how well the nitrous is read. So, an absolute answer is hard to come by. I would say you are close as your a/f tells the real story. Depending on year of your car, there is a power adder vs IAT table. What this allows is to add additional fuel while spraying only. Meaning, you log IAT's on the spray, then in table you can go to that temp area and add an additional fuel multiplier which will be added to your wot PE multiplier, Another dry tuning aid.
