"Each web site does or should give you 8 different options for a Rune.Artmonkey sorry, I don't think you need to buy an ECU because you lost the keys to your bike. Each ECU can process up to 4 new keys. Two keys came with your bike the ability to process two more new keys for the ECU currently on your bike. When I ordered my new keys recently it just ask me the bike model it did not ask for a key number. After you get your new blank keys follow the pair instructions in the service manual, you don't need special tools. If you ordered a new ECU you should be able to cancel it, if it's on back order.
The 4 models (EA,EB,DA,DB,) along with two options (A or AC) for each of those 4 models,
A being for 49 state and Canada Runes as well as the few Runes that went to the folks down-under,
and AC being California Runes.
The A or AC will come into play for the correct ECM.
Neither the A or AC option or the model option factors into ordering
the correct key blank. The key code does (more accurately the letter),
be it from the partial code of the original two keys,
or the full code under the fuel cap, or your records.
ALL of those 8 different Rune options (or 16 if you count 8 for each year 04/05)
will give you the same two different key blank options No 1 or No 2 to select from,
which is where you use the letter from either an original key,
key code from fuel tank or better yet, when you purchased a Rune you recorded it
and placed it in a safe location for that day IF you needed it.
If it was done only by Model, that would help make it far too easy to beat the H.I.S.S.,
to steal a Rune.
I've always wondered if Mother Honda recorded each key code that goes with each VIN as they came off
the assembly line. Allowing a Rune owner to simply prove to a authorized Honda Dealer they
own the Rune in question so the code can be retrieved? Or by Phone if you and your Rune are
registered with Mother Honda.
As for as ecm can process 4 keys, correct, but it's not that simple, and you don't want it to be.
IF it was that simple the Rune's H.I.S.S. would be worthless as tits on a bull,
again, making it far too easy to steal a Rune.
S/M states under step seven of the topic When all keys are lost, or ecm is faulty,
that in order to add a third key, you follow the instructions that
MO Rune Rider posted above in post #15.
The requirement to use an original key and a special tool for adding in a spare or key #3 and #4 is a good thing,
without it the H.I.S.S. would be even easier to work around."
