Pick a steep hill, and accelerate hard uphill and see what happens.... My Euro still pings with 98 RON and fuel treatment the dealer put in.

Has anyone tested this?

Off topic: The dealer also did an engine flush at the 6 month service and didn't replace the oil filter (doesn't seem normal, does it?). Will be calling him up on Monday to find out WT* they did???

I tested mine in pretty much all possible conditions, no ping at all.
P.S. I am driving the car with Caltex Premium 95 all the time.

Alright, in Perth here, Prestige Honda's got the knock sensor and software fix ready to go - gonna do the fix at the same time with my CU2 10,000km's service next week on Friday!

Wish me luck!

I dare say when pushed hard, most Euros are likely to ping....

Here is what Honda Australia had to say about this issue:

Honda Dealer - "I’ve had a call first thing this morning from my Honda Technical contact in Melbourne instructing me to pass on to you that the vehicle will require an extended learning phase of 3 full tanks of high quality fuel 95 & higher and then we need to reassess the situation."

So, there you have it....A pretty lame response to a very serious problem.

note that all honda dealer that have install the fix to CU2 owner said the same thing consistently, so it might not be a lame response afterall...

So what's this learning phase for then? If we have been filling up the car with 95 and / or 98 RON then is it still necessary?

I think overall that the Euro CU2 can't take fuel lower than 98 RON despite being stated as able to do so.

I've been running on Ultimate 98 and this has minimised any pinging so far to the point that it's not even audible.

I am now on my third tank of BP Ultimate 98 since the fix. Still a very slight ping there under moderate acceleration, but it seems fine under heavy acceleration (even under load up a steep hill). I'm not sure about this "learning" phase - if anything the noise is slightly worse on tank 3 than tank 1, but it's still very mild.

It is still necessary, if they change the mapping it takes time for the system to learn. Same if you keep changing fuels.

I stick to Caltex 95 RON and the car seems happy on it, on the odd occasion I have used 98 I noticed no difference at all.

Thanks for the info Sludge, I'll post here once I've got the car fixed next week and serviced and let's see how it goes from there!

Over a distance of 18,000km I have used Caltex 95 exclusively apart from 2 tanks of 98 that I tried several months ago (Which made no discernible difference). I have only had the software update so far - knock sensor has not been replaced yet and my pinging problem has been completely eliminated.

Thats a worry...My dumbarse service advisor told me its not pinging but post combustion detonation and hear this..The cu2 is not ivtec and does not have vtec on the exhaust side for fuel economy reasons. He also says to get the increase in power over the cl9, honda had to play with ignition timing and air/fuels.

Buddah, excuse the noob question but just wondering: most of those that still have some mild pinging have had both the software update and knock sensor replacement. Do you think there is any significance that you only had the SW update and your pinging is completely fixed? Could the software update on its own be more effective than software + knock sensor replacement?

I can't answer that with any certainty, when my software update was done I was told a knock sensor had been ordered & I would be advised when they received it. I haven't followed up on it yet as i no longer have the problem (I have done over 3,000km since the software update). It is therefore no longer an issue for me personally, but in saying that i think i did hear it very faintly on 1 occasion only for 1 or 2 seconds.

What disappoints me more is the reported response from some dealers over this problem. All I can suggest to those who get such a response would be to find another dealer.
