ECU query

[ragerover]

Bit of advice required

long story short... I've been asked to fix so friend of a friends bike (1150R)

the idiot decided to wire a sat nav in with a live from the battery and an earth
to the frame, he then decides to join the 2 together
The wire goes bright red and a pop noise
bike won't start, I've been through all the usual. I've then borrowed a mates
ecu from an 1150 adventure and it starts first time.
im going to replace the ECU. Can I use a GS one .. Seems logical as they are same motor
or can I get it fixed ??

cheers in advance

Depends on the ECU part no.

For example:-
Part 13617658618 (Control unit, Motronic, Double-Ignition) was found on the following vehicles:

259S R 1100 S 98 (0422,0432) N/A, Europe
R21 R 1150 GS 00 (0415,0495) N/A, Europe
R21A R 1150 Adventure 01(0441,0492) N/A, Europe
R22 R 1150 RS 01 (0447,0498) N/A, Europe
R22 R 1150 RT 00 (0419,0499) N/A, Europe
R28 R 1150 R 01 (0429,0439) N/A, Europe
R28 R 1150 R Rockster (0308,0318) N/A, Europe

So you will need the original R1150R ECU part no to be really sure.

None of those numbers make any sense, that I can fathom.

You never stated the year and whether it is a single spark, or twin spark.

This is the ECU for the single spark. Post 2 list the twin spark.

Part 13617658614 (CONTROL UNIT MOTRONIC) was found on the following vehicles:

R21 R 1150 GS 00 (0415,0495) N/A, Europe
R21A R 1150 Adventure 01(0441,0492) N/A, Europe
R22 R 1150 RS 01 (0447,0498) N/A, Europe
R22 R 1150 RT 00 (0419,0499) N/A, Europe
R28 R 1150 R 01 (0429,0439) N/A, Europe

Bosch part no 0 261 206 173

Motronic MA2.4

BMW part no 13617655474

Can't find any cross reference to see which other bikes this motronic was fitted too.

Edit
But Motorworks have it listed, and show alternative bikes:-

Check part numbers here: http://www.realoem.com/bmw/select.do?lang=en&kind=M&arch=0

Best to put the frame number in if the bike's near the model change date.

Check all the earth connections - the only way I can see that a short between battery + and frame could blow an ECU is if it dropped a few volts between one earth connection and another.

Good luck!
