Just seems odd that the cars without the kit very rarely suffer any issues (i.e. the engine going into overheat mode) yet with the kit on the fan is going off constantly.. must be my cynicism!
The Urban Cooling Kit is designed to improve cooling to the rear of the cylinders (in the M3W installation sense) when on the move and stationary. It also helps stabilise cylinder head temperature to improve conditions when the engine is running. The Skip Fire that is used on early cars is more of an emergency measure to prevent serious damage due to very high temperatures. High temperatures will kill your expensive S&S engine quickly. You really know when Skip Fire happens and it's not something you want to occur on a regular basis. The ECU flash that is done with the cooling fan fit to deactivate Skip Fire and control the fan running has the added benefit of a better base fuelling map than the early original. The Urban Cooling Kit is maybe not the best looking thing but it is well worth having if you want to extend the life of your engine.
