How To Pair red key to new ECU

[Bates]

Hi everyone,

So I bought a FZ6 S2, the dash and tacho wasn’t working because the previous owner had put in a different ECU because he bought as a none runner and used a ECU from another Yamaha to prove it was a ECU fault. I’ve bought a new ECU,

4S8-8591A-00-00 I believe to be the correct one.​

I’ve installed in and now I get the dash come on, however the bike just cranks and does not start. I’m thinking this is because the ECU is not paired to the Red key/immobiliser.

So my question is, how do I pair my existing red key to the new ECU?

Cheers

I would think the immobilizer would also not allow the starter operation. Fuel would be my first thought Then spark. A shot of ether would tell you if it's a fuel issue.
A dealership may have the pairing info you need.
