Tuning for different seasons.

[missin' 2]

Hey all, I know this has been covered before but I'm looking for somewhat of a method for the madness when trying to tune for cold temps 40°s vs hot summer temps 90°.

What is your preferred method?

Easiest way is to back down the boost 1, then put the engine under load 2, watch your air fuel numbers and adjust accordingly 3.
You tune for no knock and what makes the most HP on your particular application.

Typically when it gets colder out, you increase the fuel.

Makes sense. I was just wondering if there was a general guideline. Ex. Remove 20% alky and add 20% fuel. Just to make the tune close from the get go.

When you lower boost it automatically reduces alcohol

Ok, I'm running the isac right now for alky so im trying to get that dialed in but yes it does lower the duty cycle of the pump but I don't think I have the same rate%/psi as your controller. So I was just looking for a quicker way with a method for adjustment.
