That's not right Ciaran. I got my newECM and stilluse my old keys. The US keys are not
chipped, period. If they were you would see the blanked spot on the plastic (chipped keys have to have the chip facing down towards the ignition, ie the part that your fingers doesn't cover when starting the vehicle). The proof of this is all the American owners who get spare keys cut in Walmart and other places, those replacement keys are just standard blanks.
When Honda were supplying me with a new ECM, they wanted to give me a new ignition switch and keys because that's the instructions for the UK spec (HISS) models. The guys in Honda here don't know that the US bikes don't need the keys replaced and they are just playing safe and applying the recall instructions for the UK models to all
1800s, most of the time they don't know what spec our bikes are until we tell them. Mind you, you shouldn't complain if they are supplying and fiting new parts, needed or not.
UK machines with HISS have a pickup around the ignition barrel (hence the need for the coded key) that US bikes don't have and this is looped into the main connector block that feeds into the ECM. There is probably a way to bypass this, but I haven't had the need to look into this personally.
You will notice an improvement with the ECM Ciaran, no more OH in traffic or parades. Some people say the bike runs better as well, but for the life of me I can't see any difference other than the temp needle stays just under the halfway mark all the time.
As for turboterry's
problem (BTW welcome to the forum), I think a trip to a specialist is in order. There's plenty of specialists in the UK who can supply coded keys for ECMs. You see them advertised in car magazine all the time.
Good news for
turboterry. I misread your profile and assumed you were from the UK. I now see you are in the USA, so you don't need to go to any specialists. The good news is your old keys will work fine with any GL1800 ECM. If you give your dealer a heads-up on this it will stop people being misinformed and wasting their cash on parts they don't need.
Also, if it helps, there is a tutorial on replacing the ECM on this page https://www.goldwingfacts.com/1800ECM.htm
