Do weather condition effect VVE ???

I did my VVE tune in 100F and high humidity...

Does anyone know how weather conditions effect VVE tune ??? If i was to scan in 60F weather, would it require changes ??

Anyone know ???

Iat is part of te formula and is directly related to ambient temps so yes it is effected

I think theres an editable field that says what temp it was calibrated in. It says 68* stock and I zeroed mine in when it was that temp outside to be sure. I?m pretty sure that?s what the description stated

i completely missed that VE Base Temp setting... fail... i am guessing this is my IAT not ambient temperature ??? Can i just set this to 115F as that is what my IAT were ??

BTW car is big cam, procharger, MAF breakout.

Humidity would if you havent address the humidity table.

Are you talking about spark humidity table ?? i don't see one directly related to VVE.

How would you go about tuning for humidity?

Turn off the temp setting option, tune VVE, then turn it on with your actual temp displayed in the PID. The car references the ambient temp. And watch out for the reflash which makes ambient read 32degrees, mine has done this a number of times in the past. Random stuff to watch out for.

The trucks do this A LOT! Hahahaha.

Running the vehicle at 55 mph for 2 minutes should get the ambient reading back to proper.

I got the 32 degree ambient issue also after flashing my VVE logging tune to the car. How are you correcting? Just flash again?

Just drive it and in about 10 minutes it goes back to normal temp

Thanks Ben. So if I am doing my VVE tuning and corrections in 91 degree ambient tenps outside, I need to set the base temp to 91 degree vs 68 when I re-enable tenp correction?

I only tune VVE when it's 68 degrees outside.
