After reading posts and playing with INPA i understand that there is no connection between cold start problem and valve lifting setting! When you start your car the valve lift is set to default 6mm and keeps it until rpm fall to 600 and that is the time period usually until when CE light flash. Even after that valve lift changes to other default setting which is 0.3 mm and keeps that level for some time until the engine warms up. I am not 100% sure if the timing is exactly the same, but it seems that valve lift changes to set height which you have set in INPA only then when INPA allows you to change valve lift setting.

So basically set valve lifting kicks in only after short drive when engine is warm when the CE light have flashed long time ago, so valve lifting can make difference only to a warm engine, not cold start.

So my question is that what happens to fuel consumption and power when you lift the valve ? If valve it set to 0.8 mm the fuel consumption is greater but also more responsive throttle and better acceleration ? And if set to 0.3 mm then fuel consumption is less and also less responsive throttle with not so good acceleration? Or it is the other way around ?
