Anyone spraying dry with SD???
easiest way, is to use a resistor and a relay to change between Nitrous values and NA values..
basically the resistor is a value that equates to an IAT of 192* or something high and off the scale(it will be a low value in Ohms...)
when you flip a switch, your vehicle goes from using the stock IAT sensor, over to the resistor as its temperature value.
you can then remove timing for nitrous in the IAT spark tables.
and for a Dry shot you can add fuel at WOT via that IAT PE adder tables
it makes no difference whether you are using the MAF or in SD....
only difference is that in SD, you only have a low octane timing table unless you update to a Custom OS, and on 98-00 OS's you will be using a have size secondary VE table...
and FYI... even though I am not the stock pcm...
I spray Dry, and in SD and its not a small shot
(350...soon to be 500)
