ΠΡΟΣΟΧΗ!

whatever I do here, I do on my own motorcycle and I take responsibility for it, my own motorcycle!

If you decide to do something along these lines and break/disarm/annihilate/exterminate your motorcycle, it's totally your own responsibility!

So, as clearly as this can be said: I AM NOT RESPONSIBLE for your damages!!!!

How to install John Gemi's Chip on a R1100GS or R1150GS!

I have installed John Gemi's chip on my bike, a few years ago and it was a real gem (no pun intended!).





So, when my friend Spyros showed up one day at my home with his newly acquired 2002 R1150GS, while we talked over the bikes, and what's different from the 1100 he used to have, I mentioned the chip!

Of course we ordered the John Gemi Chip then and there. A week later it appeared on my door!

Since Spyros was on vacation with his family, he entrusted me with his bike, so I installed the chip on it and did the first ride, too! I had ridden it before, as well, so I knew what would change!



So, first of all, the tank must go back. Then, we disconect the minus from the battery.



Using a short extension and ratchet we loosen the four philips head bolts that hold the bike's ECU on the frame and remove them.
As you can see, the previous owner found the lower bolt convenient to add a ground wire AND to mount the relay for the aux lights on the bolt! Oh well.



Then we move the ECU out of its resting place, so we can remove the plug.



The plug is easily removed then.



We have the ECU on the table.





Using the correct bit we remove the four bolts on the ECU cover.



Using a flat blade screwdriver or two, we pry open the two halves of the ECU. Taking our time to do this pays dividends. We must be extra careful not to scratch anything INSIDE the ECU, between the two halves...



With a small flat blade screwdriver we remove the plastic cover that sits over the original chip.



Remove the chip! Extra Careful here! Take your time!
As you can see I managed to slightly crack the chip's base at the right side. No real harm done. A small drop of CA fixed this minor incident. So, be EXTRA Careful!



Mount the new chip in its position. Make sure you put it with the correct orientation. Before removing the original chip take a photo and observe where the indentation on the end of the chip is (in this photo its on the right, as pointed by the arrow!).

Before CAREFULLY closing again the two aluminum halves, put some high temperature silicone sealer and seal the ECU absolutely and completely, right on the perimeter of the ECU, taking your time to do it right.
You will see a 20+ years old sealer there...

Reinstall everything back on the bike. Don't forget that washer there!!!
Make sure the right throttle cable is seated again correctly. It ALWAYS goes out of its seat when you remove the tank!





Enjoy the ride!





What washer? See? I got your attention!
