I dont dispute fuel can be used to cool a cylinder BUT there is STILL combustion creating heat !!!!
(Assuming the spark is still active of course)

No combustion = NO HEAT !

As I said before, why waste fuel cooling a cylinder that shouldnt need cooling if the engine is mapped correctly.

So, lets suppose this "cooling" is being done deliberately....
You are driving up the road flat out...when do you know the cylinders "need" cooling ?

5 seconds, 10 seconds, 1 minute, 10 minutes ????

The answer = when it melts a piston because it hasnt been mapped properly or caused by an external fault.

Surprised the expert tuners are not adding their 2 pence worth .....
