Planing on going to the dyno this winter, and was curious what temperature is too cold verses to hot!

 

The colder the better. If its extremely cold, the far left side of the IAT spark adder table that you never pay attention to may come into play. For what is enough timing at 70 degrees probably isn't enough at 30 degrees.

 

So if I tuned it for the cold weather, then I might run into some knock issues during the 100+ summer?

 

No, you just pull timing for high IAT.

 

pay more attention to density altitude than the temps. it's a combination of temp and humidity. dry cool air is great. damp cold air not as much. also, damp cold air makes for shitty traction. you can usually just go off of the hoods on parked cars. once the roof/hood/bedsides start beading up, the racing is going down hill.

 

what he said, here in florida its always damp

 

Most dynos run corrected numbers so you can get accurate comparisons if you dyno in december then make changes and dyno again in july. you can see the uncorrected numbers, but if you are looking for a number to work off of you need to see the corrected numbers so you dont always wait for the perfect day to dyno.

 

Awh, I see what you are talking about, Thanks. Just got the soft ware a weekish ago, there's a lot of **** haha

 

Nice tips, I have been watching the ike gaunlet of the new trucks, they say going from 10K-12K feet is roughly loosing 30% air density, which is in range of a 30% power loss

I'm in dfw area so its some what close to sea level here, but most days are dry air except rain season gets pretty humid
