Hi, Folks;
I developed a nitro engine tuning setup sheet for high and low speed needle settings a function of temperature, atmospheric pressure, and humidity. ESPECIALLY TO NOT LOSE TRACK AS TO WHERE THE NEEDLES ARE POSITIONED.
Way it works........ From baseline nitro engine OEM HSN/LSN settings - in addition to following tried and trued engine tuning techniques (considering all tuning aspects such as Nitro content in fuel, oil content in fuel, glow plug type, etc.):
a) Record weather temp (F or C), pressure (in-Hg), relative humidity (% of sat vapor pressure at the curren temperature) - then Calculate ACTUAL AIR Pressure (this will backout any component of humidity).
b) Consider current air pressure (air has fixed % of O2 ex humidity) - then use this as part of your tuning exercises.
c) Record the current (or updated) HSN and LSN settings at the optimal tune point as a function of the actual air pressure (ex humidity).
If you put your model up over the winter, in storage, etc... your tracking sheet will have the Needle Settings and the associated climatic aspects at the time of the last run so you will not get 'lost' in terms of your needle positions.
While the Pros and others will for sure have a similar tool, you may very well get use out of this setup sheet - newbie or experienced. So I figured I share my tool with the community @ large.
