[curtis265]

one side is fine

positive side (red)

i thougt you're supposed to do the negative side?




good to hear ur car's fast again

i reckon your fuel consumption will go back up though

Yes if you disconnect your battery, always disconnect the negative (black side) first, and reconnect it last.

Either way, can't see the point of having both off lol

yeah, no point. just do one (negative terminal), 10-15 mins later, come back, done and dusted.

I read from the tsx forum that you can get the ECU updated with the latest honda's firmware by a dealer. Have anyone requested for this service to be done to their accord euros and if so, at what cost? Some firmware update will recalibrate the engine performance or the transmission according to the tsx post.

an american TSB doesn't mean it's released here

Guess I'll just have to ask them dealers

Ooft, the problem is still there The fuel tank is abit above half and its on about 270 k/m on its current tank, whereas it's normally sitting on like 210 at that point. And again power loss is most noticeable when going up hill.
Should I just get it checked out at a mechanic?

We have just installed our 3rd ECU at the dealers.

Our car, an 2005 Accord Euro luxury, was running poorly over a long period, lacking power, acceleration, and had difficulty pulling a small box trailer.

Then the dealer found ants in the ECU. I thought this was a joke but there were quite a lot of ants.

Apparently they are attracted to the resin that coats the circuit board.

We installed a second ECU but it only lasted two weeks and the VSA stopped working, and the MIL came on. Dealer pulled the ECU and it had more ants in it.

We've just put the 3rd in and sprayed the inside of the car with ant spray, also the ECU case and around where it is mounted.

Still don't think it's possible? When I bought this 3rd ECU (I had the 2nd one already) from Honbits Todd told me they had sold several already, all for the same problem.

So check inside your ECU if you are having problems with performance and economy. It only takes about 10minutes and is worth peace of mind.

A new ECU from Honda - $2,500 installed. Even a used unit is about $400.

The ECU is mounted behind the centre console, held in by two 10mm bolts, behind some plastic trims pieces on both sides. The driver's side you have to remove the footrest - it just clips off.
