Getting ready to finish rebuilding my engine and install a dry nitrous system onto it.
Just want to check how to get a rough guess on where to set my additional fuel pulsewidth to.
I am going to be installing much larger injectors and re-tuning it N/A before I start doing nitrous, but using last years tune for example, let me know if I have this right:
My required fuel is 9.5, 2 squirts per cycle, so my ms is 4.75.
A point on my VE table where my car makes 100hp is tuned to a numeric value of 72.
If I were to run a 100hp shot of nitrous, would I multiply 4.75 by 0.72 to get my additional fuel pulsewidth of 3.563, maybe to be safe for the first run multiply it by an additoinal 25% to make up for flywheel hp being higher than the chassis dyno shows, and be a bit rich to be safe? So start at 4.450? I will obviously wait until I dynotune it N/A with the new injectors before looking at what numbers to reference, but is my math right?
Appreciate the help, just want to make sure the first time I hit the button, I don't do something horrible to my engine.
