According to dyno jet,They do not make a map for NOS,,But after talking with ryan from schnitz raceing,is easy,,,Of course the best way to tune is dyno,,but you can get a map from powercommander to the specs of your add on's and insert it raiseing your full level at WOT position at 8000 rpms for the % of fuel needed for the size of the shot your useing ,and thats it,,read their nos chart from schnitz,,you can get it off their website,,,,I started my increase at 7000 at 16% [15 reommended for a 40 shot] on my bike,,,the rest of the map can be just a standard map from dyno jet,,when adding Nos,,you only have to add the fuel at WOT only,,ryan also suggested that some of his guys will add alittle more at the 80% throttle postion,to have extra fuel when you let off of it to clean the airbox out,,another issue is,,even tho you insert a map with your add ons,,doesnt mean its going to run well on your bike,,all bikes even tho their the same brand name and cc and add ons,,the same map will act differently in each one,,so in my own opion,,its a stating point,and ryan agrree'd.. dyno if you can,,but if you have tech experince and a good ear for motors,,you can tweak your map by hand,,in 1st or 2nd,,roll from a start easy on the throttle in incriments and monitor the surgeing rpm range and the throttle postion where your hand is,,mark it down and continue to the upper rpm range,then do 2nd gear the same way,,its painstakeing,,,but it works,,the go in to your computer and pull up the exsisting map and see what the numbers are in that range[throttle postion and rpm,,and ussually you;ll see it either straveing or a huge increase infule drowning the motor down In that particular cell ,,,,,,dynojet recommends something like that with the low-mid-high buttons on the PC when your driveing ,you can pull over and make the adjustment,,but I dont know of anyone ho has done that agrreable with randy at dynojet,,,,it easier to do it the way i discussed up top,,,you can use someone elses map,,even with NOS ,,if your running about the same setup,some tweaking may come into play,,but Ive down numerous of them and they turn out good,,,remember the map can be used from another bike,,no different than downloading one from DJ,,,its where the extra fuel is that matter when you spray,,and by the way,,ryan doesnt agree with spraying at a low rpm,,neither do I,,it slaves the motor and put too big of a load on it,,,thats why I dont like TB activated NOS at WOT,,,,I dont need it in 1st gear or how if I hit WOT in !st or @nd at 2000 rpm's? thers goes the Nos kicking in,,,I prefer a switch,,I used the 6 pole from Schnitz and wired it into my horn button,,,,,I also added 7% more fuel @ WOT at 5000-6000 rpms then 16 % at 7000 on up,,that why if I hit the Nos at 5000 by the time it gets to the airbox from the solonoid, I'm at 7 plus rpms anyway,,,,sweet deal,,,,
