[CU2] To all the new Euro Auto owner out there!!!!

[Bobjones]

With a lot of letters to the media about the same engine noise we are all experiencing finally Honda have caved in and given me an answer. It is as follows... Software fix is reputedly available mid February

Dear John, 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

Hmmm I would like to see what this fix really is. Just glad they have "identified it" though I have large doubts that "post ignition" does not cause any damage. So what they are trying to say is that the ECU tune is FUBAR, we will adjust it to use more fuel, retard timing or a combination of both??

The higher CR may have an effect, and 0.5 CR is a large variable, but can easily be adjusted with a head gasket, alot turbo engines get thicker/sandwich head gaskets to lower CR to run more boost, at the detriment of lower down torque at times though, but the benefit is less chance of detonation due to AFR's being too low, especially if running higher octane fuel...

I am not holding by breath for end of Feb, more like end of March if the Honda dealer is anything to go by???

If all trip computers on the CU2 read the same they read 0.4L/100 below true reading - eg, if it reads 7.2, true reading 7.6. My best to date is 784km - 54.59lts = 6.96. Amazing for a CU2 Auto

Yeah, still blows me away how fuel efficient this car is.

I think it is the fuel mixtures.

Weren't you the one that had the ignition retarded? Apparently that didn't work.

I took my Lux manual out on the weekend and with about 80% highway and the aircon on for most of the time the trip computer was showing an average of 7.3 litres per 100 k's. Pretty happy with that. My manual has no weird noises and I could not be happier with the car.

Hey SteveH
Could you tell em what build date is your Euro.
Mine is 1-May-2008.
Im just curious due to the fact that certain May build cars have had this NOISE that everyone is talking about.
Mine has it as well.
Apart from that the car is awesome.
Love taking it over 4000RPM blows me away...
It has 3,200 kms

Build date on mine is November 2008. I have only just clocked up 1,000 k's, so it is probably still too early to tell if the noise will appear

Thanks SteveH

This is quite interesting as most other Euro's who have a different build date
apart from May 2008 do not have the acceleration rattle or pinging noise as we all call it.
This is my forst Honda car and im dissapointed since the rest of the car i sreally first class, it gets plenty of stares from onlookers.
It has that x factor the others dont have.
Anyhow im hopeful Honda Australia helps all the other owners who have lodged a complaint.

If they dont its going to end up crap creek.
The car of the year will then become the rattle of the century

Mate when i purchased the Euro the dealer threw in the non standard
gear shift from the accesories list, it really compliements the interior quite nicely. Do you have any hassle with the standars gear shift?

Mines a May '08 with 14,669kms.
Not that it's a bad thing, but I can't replicate the dreaded 'noise' no matter what I do.
Lug it, rev it, nothing.

Quoted your post dude...
So you are trying to say that if you don't have a May '08 you wont have rattle?

What I want to know is how do you know?

I had 06 Euro 6SP manual (best car I'll ever own) and was always getting 6.2L/100km on
Sydney to Canberra trip.

I now own 08 non euro accord that also pings like euro. Took it to the dealer and was told that they are waiting for solution from Honda Japan to try and resolve the issue. Non Euro is supposed to run 91RON but it still pings when using 98RON. GrRRRRR
