I recently had to replace the ECU to another 2:hand unit. The new pre-owned ECU has all the same markings and codes, production date is a few months apart to the original unit. Thr problem I have is that when I try to start the bike I get an ”EWS”- code in the display. I guess it is the immobilizer ...

Alright thanks buddy !

Thanks,

I hope someone would be able to help !

Hello From Helsinki, Finland

Nice Forum you've got here :-)
Bought today a nice 2005 R1200RT with 100 tkm on the dial. I have an old K100 cafe racer build in the garage as well.
This R1200RT however, has a ground problem in the ECU, at least I suspect it. Would love to get my hands on a pinout ...
