How does the hot exhaust gas cool the fresh charge.... Or have I got this 
wrong and you mean that the exhaust gas isn't heating the cool intake 
charge and the cold intake charge is causing the detonation????

Either way I'd be very surprised if lack of ERG had anything to do with 
increased detonation.
