Replaced ECU and bike won't start.

[Robertboulter]

Went for a ride out to Matlock Bath in September last year and she died on the A50 with a strong smell of sulphur. The battery had started to melt so I disconnected it. got home and found the reg/rec to generator plug had failed blowing all the bulbs ,melting the battery and killing the ECU. All the bulbs and fuses have been replaced, the reg/rectifier tested (was ok) and a new plug fitted. managed to acquire a good used ECU but bike still won't start. I'm getting a flashing red F1 light ,the code is c42 which I believe is ignition switch signal. Does the ECU need to be married to the bike as with cars or is there another problem.

You do have a small led next to the key, correct?
That is the ignition immobilizer light.
Your new ecu needs flashed by the dealer or with Woolrich, so the dash, ecu, and ignition can communicate.

@sixpack577

how did u find out the bike is a gen2?

@Robertboulter

1. in the net one can find guys who can flash out the immobilizer
and then every gen2 ecu works

2. where the heck are you from ?

3. with your next tech question ever , mention the type of your busa clearly sp that even stupid guy like me can easyly understand what ur talking about.

Sorry for the late reply fellas, had a busy couple of weeks. Managed to get the keys from the bike the ECU came from and it's now running. Just waiting for a Mofset regulator rectifier and cooling fan relay to arrive and I'll be out and about. Makes sense to fit a Mofset reg/rec as this seems to be the Busas achilles heel and this should prevent a reoccurrence
