Title: ECU K75S 1988? two types
Post by: bjorgk on January 07, 2018, 10:48:04 PM

Hello
I bought a K75S 1988, but it's missing the Ecu, fuel injection module.


I've searched ebay. There are two types. 0280000376 for 1990 with a blue label and 0280000332 with a red label advertised for 83-96. The blue is cheaper. Can I use both?


Do I need a mounting bracket too?

You can use both, 32 is the standard version, 76 is a cop version which have a better RFI shield.
If you don't have the plastic frame you need that to, it's two Versions...one for the standard seat
and another for the low seat.
The mounting rubbers for the plastic frame and lock pin to keep the ECU in the frame you probably
need to.

Thank you very much. I found the plastic frame.. I thought there was one more frame. When I checked it had 2 round holes on one side. And one in the back. A compartment. Was above the battery.


I ordered this then,.

It has the mounting rubber. Then it seems I'm only missing the lock pin. From google it seems this is how it should look. http://i45.servimg.com/u/f45/14/15/33/08/dd10.jpg. Maybe I can make something similar. Or order new.


Thanks again. Then that issue is solved. Hopefully I will find out if I got a working bike in about a week.
