Lean every time weather is cold
Is there any solution to this problem? There is at least a factor of 2 difference (afrs + 2 ex 16 instead of 14) every time the air gets cooler.
And no, it's not just the afterstart enrichments, this happens once the car is warm too.
Would the solution be to have 2 or more VE tables to use according to the weather, because that would be a pain in the ***.

Sorry that I can't be of help for a proper solution. But the solution that you suggest above is definitely not a good one. You really have to find the source of your problem because assuming that you will always have this offset and running 2 different maps is a bandaid at best and a blown engine at worst.

i imagine the megasquirt has an air temp sensor for this very reason... air temp enrichment. set it so it adds fuel when the temp is lower. i'm sure someone has a set of values here.

I don't have an issue with this, though when it's cold I tend to let the car warm up a little. You can use IAT based enrichment but it sounds like your IAT sensor isn't reading right because the MS should make corrections based on IAT. You can go into advanced- coolant based density, then set it up for IAT based enrichment and adjust your values in the table accordingly.

Actually-- that may very well have the old firmware and config files-- that's when I was on the dyno figuring out the need for a change, and around that time it was implemented, but if you bought in early December it's entirely possible you need to update to the latest firmware and tuning software. It specifically addresses this. It's also assuming you're using our IAT sensor if you've done a MAF delete.
