Dear xxxx, we appreciate that you are concerned about the presence of an engine operational sound as it detracts from your overall enjoyment of the vehicle and we wish to again reassure you that this condition will have no impact on performance or engine reliability. We have been working closely with the technical division of Honda Corporation in Japan and following extensive investigations we can confirm that the condition you are experiencing is not that of “pinging” which is known within the industry as “pre-ignition”. The condition that you are experiencing is a combustion sound taking place after the programmed ignition, namely a “post combustion noise”. As this condition takes place after the programmed ignition and with the piston on its downward stroke, there is no detrimental force or impact within the engine in your vehicle. Therefore your engine has not sustained any damage and we are happy to offer you a guarantee on the engine while you are the owner of this vehicle as a way of reassuring you of our confidence that no wear or damage is occurring to the engine or associated components.

We trust this advice from the manufacturer clarifies the matter.

Regards
Joe Gelsi
Customer Relations Manager

Interesting. It's cool they included all that relatively technical information in there.

MMsTSX

so basically they just told you to deal with it.
they will do nothing to fix it, it won't hurt your engine, so deal with it.
what a bunch of crap.

Why is it a bunch of crap? Different engines make different noises/sounds. I don't even notice it, and if it doesn't hurt the engine in any way, why worry about it? I'm satisfied with their explaination and response.

I guess it will be an easy retune of the ecu.
