EPROM Installation Notes.
BMW Motronik R 1100 R/GS
1.
Make sure that the ignition is switched off! Start
by removing the Motronik housing (under the tank
before the ABS). You will need to remove the tank
first. Once you have found the housing (square
aluminum box with rounded corners) undo the small
screws holding the unit in place. The tie clips
you undo also seal the housing shut, so don't
lose them.
2.
To open the two sides of the housing use a Torx
screwdriver, no 30, if you don't have one don't
worry. Tubing pliers and little screwdriver work
just as well. There is a seal of silicone (all
the way round) connecting the front and back of
the housing. It often sticks very strongly. Lever
the front and back apart careful by inserting
a flat head screwdriver or similar. Work you're
away around the edges gently prizing the edges
apart. Don't try to open a side in one go; by
working your way round the housing the silicone
seal will split evenly and easily. If the silicone
sealing is a little damaged, don't worry it is
absolutely no problem. Don't use new silicon for
sealing again.
3.
Locate the socketed chip on the printed circuit
board. This can be readily identified by the white
plastic "H" shaped retaining clip, which holds
the chip securely in place. Remove the H-clip
with a small screwdriver, inserted into one of
the two small slots opposite each other, in the
center of the clip. ' Each Eprom has a marking
(notches on the side) to prevent inadvertent rotating
of the chip. The base version on the circuit board
is soldered (cannot be removed) and has notch's
matching that of the Eprom.
4.
Remove original chip from the socket by inserting
a screwdriver between the short end of the chip
and the socket. Pry up gently, work slowly and
gently pry from alternating ends of the chip.
Do not try to pull
the chip out by hand. Do
not pry the socket away from the printed circuit
board! The BBPower Eprom uses the
same socket to attach it to the circuit board
(the green base under the Chip).
Assemble.
5.
Once the new chip is locked onto the circuit board
(using the above mentioned socket) close the housing
(do not reseal with new silicone). The locking
clips should click audibly. Gently Re-bend the
clip if necessary!
6.
Important! - before you complete:
Before putting everything back in place perform
this quick test. Turn on the ignition and listen
to the fuel pump, it should stop after a few seconds.
If it does not the program has not kicked in.
In which case switch off immediately. If this
happens its best to call Motorworks ad get some
advice. You've either got a faulty chip (un-likely)
or you installed the chip incorrectly. However,
their advice should be sought.
7.
The chip includes 8 programs and is supplied with
a small spade connector. The spade connector is
to replace the built in coding plug found in the
fuse box under the seat.
