Resistor mod for NOS
OK, I don't remember where I saw this, but I thought I would post here to try to get you guys to help me to understand this. I read somewhere about someone putting a 1000 ohm resistor in series with the temp. sensor to fool the bike into richening the mixture when running a dry shot of NOS. Here are my questions:
1. Is this the 'resistor mod' that I keep hearing about?
2. Does the extra resistance make the bike think that it's running hot/lean?
3. Is this something that people do if they're too cheap to buy and install a PCIIIr?

1.Yes
2.IT UPS THE FUEL I BELIEVE 8% ACROSS THE BOARD
3.Yes,we did this before the pc3 came out to take some of the stumble out when a aftermarket pipe was put on.Now i still use this instead of a powercomander because i have never seen one fail as i have witnesses and heard of alot of pc3r fail.
Use a 1/4 watt 470ohm resistor

I think there are some tuning issues here nitrous is dangerous in any motor if not tuned properly, I have three bikes with dry shots 285 hp stock motors in them all the temp change in the box will up the maps approx .08 % with a 30 shot across the board, the resistor mod on the coolant temp sensor will up that to 14% with a 640 ohm 1/4 watt resistor and will go as high as 21% with a 1000 ohm !/2 watt resistor which is good to 50 hp dry with a/f at 12:1 or 13.5:1 at 60 hp. What do you want to know about the dry system I designed one for my 12 feb 00 on the prototype Kawi had nad have done close to 200 bikes personally and never had a problem or complaint except for two people tossing shims with a shifter atr rev limiter. The question on the 56 and two 38 pills will vary large on setup and proper tuning with two 38 jets from nos with the resistor mod and c-16 fuel you will have 247-253 hp at the tire, the 56 pill from nos with same mods will give you 251-262 hp, the difference is that the twins will be a two stage system and ramp power differently then a single 56 which will ramp power very quickly. Please feel free to email me at home with any dry nitrous questions.
ARH: I find that most have no idea about nitrous and I go out of my way with all my customers on how nitrous works and what to watch for I'm not here to bash just update some well needed info apperently.
