Trying to see if if i can spray dry with speed density??If so how are you guys doing it???

I used to spray a dry shot in SD, used EFI Live Custom Operating System 5 to add the fuel. It worked great but I then went to a plate from Nitrous Outlet.

2 stage dry thru a nitrous outlet plate...
Small 200 shot...
Iat method, works well for how I use the car...
OLSD since 2007...

Thats what I plan on doing... maybe to help me with a base, about how much fuel were you adding? If you remember, or have the file stilll...

Did it thru the coolant temp on a switch. Nitrous tune on the flip, na had full potential when off.

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)
