With your setup, you're good to go already!! The PCV + Autotune will monitor your AFR both on nitrous and off. Thus, when you depress the button to activate your nitrous solenoid, the Autotune will see an attempted spike in AFR, and increase fuel delivery immediately. Once you let go of the button, it will scale back fuel delivery automatically. Neat stuff!!! A +15HP shot is quick, still easy on the engine, and the power increase is amazingly handy.So what's the best way to get a small shot on a newer efi bike? Do you need to remap the bike? My bike has open loop efi and a power commander with auto tuner O2 sensor so it's possible it might be able to just add more fuel as needed when the NOS switch is hit?
Very cool! So to do it with auto tune would you open up the maximum fuel trim change on the pcv? It's normally set to only allow +\- 20 values but if that's not enough to compensate during NoS could be problematic.With your setup, you're good to go already!!

While your PCV + Autotune method is one style to fuel for nitrous usage, since any PCV carries two maps at the same time toggleable at the flip of a switch or button - (which is how I wired in my PCV fueled Nitrous kit this season) - pressing the nitrous solenoid button changes over to the "Nitrous Map", and then releasing just runs the normal map is another direction any user can employ.
Happy Summer Folks!

Opening up the allowable Enrichment/Enleanment range is a great idea. 20% might be on the edge of being just enough for low HP shots and is plenty for the average non-NOS user, but a wider range will enable you to adjust fuel to a larger delivery when larger shots are installed.Very cool!

Also, if you have it set for non auto tune and just switch two maps would you need to dyno the second map to work at WOT and NoS? Otherwise wouldn't you be guessing somewhat?
We run 2.5# bottles, a 10 would be huge for this application. It would be fairly hard to package and way more nitrous then you would practically burn in multiple rides.Also what size bottle is best to run? Found a good deal on a 10lb bottle but that might be too large
Has anyone put a nitrous kit on a KX450?
I basically pieced together my own kit starting with the 2.5lb bottle and valve from DynoTune. Sought after a low draw/high flow solenoid, paired it with a sleek hidden bottle mount, added some fancy jets up to .054 orifice (wayyy too much for most days or engines to hold together, but cold bottles/low pressures don't flow optimally), and came together perfectly all on a bargain budget! In the end, any dry nitrous kit will work with the PCV - Dynojet has been doing it for years.TJ,
What kit were you using with the PCV? I have a pcv and am thinking of getting autotune and possibly a nitrous kit and would like the most seamless painless route to get it to work together happily.
Thanks
