- Fuel
--> <<Advanced Fuel>>
----> Fuel Trims
------> Air Temp Fuel Corr Table


You whole map is more than likely set at 0. So what you are going to need to do is modify that table, and add fuel when it is cold, and remove fuel when it gets hot.

So as you are driving around in cold weather try to adjust that table and get your AFR's to match where you were tuned at.

Here is a SAMPLE of what I am using, which for me is still off on pump gas and race gas, I have not fully tweaked it.

34.375 28.90625 23.828125 19.140625 14.453125 10.546875 6.640625 3.125 0 -3.125 -5.859375 -8.59375 -11.328125 -13.671875 -16.015625 -18.359375 -20.3125
-40 Degrees --------------------------[104 degrees]---------------------------> 248 degrees

Use at your own risk.
I took this from the Boost Comp Excel sheet on aempower forums.

while this is true in many places, here in Puerto Rico your starting air temps could be in the high 80's when initially starting your car, and rise to about 95-100 when driving. What you should check is what cell of the fuel map is highlighted when cold(coolant temp) and compare it's value with the one highlighted when @ normal operating tempertaure.

BTW, let me know when you get your fuel assembly.

WOW... great... did that, plus did little adjustments at the Warm Up Enrich table, the Start Decay, and the Start Extra table, and after two days of not using the car, it started the first try... and it went very smooth while warming up..!!

Once again thanks..!!
