Cold map??

[tb205gti]

Why is it very noticeably slower when cold then?

I was always under the impression you need more fuel when cold as some of it sticks to the cylinder walls or is lost down the sides or the piston. Maybe not a different map altogether, but must be some difference in the map when the engines cold?

There are a lot of compensator maps that gives a slightly richer mixture when it is cold, because internal losses are greater when the engine is cold. The injectors hit the bowl in the piston, if they hit the cylinder walls - you have a serious defect

but there is not a set of maps that define a "cold map" in it - unless you make that yourself.
