tempature and VTune

[frankieb]

How does the cooler weather effect vtune sessions? What is the temperature threshold of being to cold to get an accurate vtune?

One of the nice features in the V-tune window is the vitals that turn from yellow to green when within operating range has been met.
ie: V-tuning will start @ 167 deg.

C or F?

True, but would the cooler, denser, drier air in winter make for an inaccurate tune come hot & humid summer?

More so with timing than mixture.  As long as the vtune is done within the 167 and up the sensors will take this into account from what I've seen. I believe there is also an upper limit for vtune in around the 290 area. I think I saw it once in the shop.
In the end the best overall mixture and timing all in one package seems to work out better in warmer weather. Hinged around the timing as the deciding factor.
