The original key and Hiss ECU are a pair, you cant interchange them, but you can use a new ignition if the chip is taken out of your original key and attached to your new key, you can buy an antenna from ebay, that just transmits the password to the ECU and back to the antenna (all done in milli seconds), have a look on You Tube ,there are various video's explaining it

Okay. So the HISS is not paired with the key, the ECU is?

Thats good to know. Then I can do as you suggest and buy a HISS that is "universal" and use the new ingition and ECU. Because they are a match.

 

The Hiss system is within the ECU, the antenna reads the chip in the key and confirms with the ECU that the key in use is the one paired with the ECU, so its the original key (with chip inside) that the antenna wants to read, as long as the chip is as close to the antenna as can be ,the antenna will read it, but try this out first before you put money out on a new ECU and Programmed key, so its just the antenna needed and new ignition switch if thats destroyed

 

I understand. The thing is that i bought a new ECU and hopefully a programmed key, but the seller forgot or left out the antenna. So I was not surprised when using the old antenna didnt work. That is why if I understand it correctly i only need a new antenna now. I could have made it cheaper for myself. Could have left out the new ECU. But if I buy a antenna it would work. If the motor is not fu**ed.

Do you know if I can buy the antenna from another Honda bike of the same age? If not I could buy from Ebay. I am norwegian so it would probably get customs on it. But its worth it.

anyways, thanks a lot for the help. I was thinking about selling it for parts, but thats a shame because the bike was really good before it got stolen. Maby I could get 5000 dollar for it in norway.

 

Have a look at #11, there is one there, but remember if you try to take out the chip from the key you could destroy the chip , and if you fix the chipped part of the key to the antenna anybody could steal your bike, or even steal the chip and your back where you started,This pdf will explain it better

 

I saw it. And I have already made the order

I have a matched key and ECU so that would not be a problem.

Crossing my fingers that it would work!
