All the possible solutions are not looking good!Originally Posted by SPQR
This sounds like it's got through the "veil" to Honda Japan. This is good. I have found by previous experience that it's only when the Japanese manufacturer hears of the problem that real solutions happen.
However, I think the issue arises from the high compression ratio of the engine. As it's pretty hard to change, the solution might be 1) You all must use 98 RON petrol; or 2) They take your cars and tell you they're going to fix it but in the workshop they upload a new programme for the engine computer that retards the timing or squirts more fuel in for a given load.
Neither solution is really acceptable as both come at a cost at the petrol pumps for the owners.
Solution 3 could be that it is was a dud knock sensor (or O2 sensor) afterall (that explains why not all cars have the problem). The solution for this is a replacement sensor. I hope it's something as easy as that.
I did not experience the problem when I test drove the car and our one dealer in Darwin is too tight to fill the tank with 98 RON (at $2.00 per litre at the time of the test drive!) so the test car would have had 95 RON in the tank. And its hot up here; so it's the worst conditions for "pinging".
