I was referring to the Nightrider 'level shifter' piece you mentioned. Not your LC-1.
The tuning on my bmw r1100gs is continue.
I think to use two ignition coil parallel for better fire spark. The bosch coil gives up to 12.000 Volt. I dont know what happen and how long will be the voltage by one battery. Have anyone some idea how to make the connection by register or by AC Adapter for the seccond coil ?? I will try to use an AC adapter for low voltage at the second coil. Etc 12 V for the first coil and 4-6 Volt for the second. So i think that the new high voltage on the spark being 14-16.000 Volt .
I want to make my R1100 gs to gives up 8.000 rpn. I make new camshaft and new pistons, compress ratio up to 12:1, free air and exchaust..
Now by my old setup, with ratio 11:1 and camshaft from r1100s, the engine gives until 7.500 rpn and i think the power could be continue up to 8.000 rpn. So i need more compres ratio, more fuel, dual pin plug sparks.
The dual sparks is this one (NGK BKR6EK) and work fine on R1100GS :
I am having some trouble tunning a 1150GSA, 2003, servo model.
No matter what I do, the spark plugs are white.
The bike came without a CCP. I installed a jumper wire like this - http://t2.gstatic.com/images?q=tbn:ANd9GcQ5fPFVlaKjuRMlmDr9dp2IrBdvLC1RXwh_vWpAxre_JSm-KT2RwA
That did not change anything, as the spark plugs are still white.
The bike now feels a little like powerless. It pulls, but it does not feel as a regular 1150GSA.
I did run a diagnose on the GS911 and I can see that the graph for the O2 sensor looks normal, like /\/\/\/\/\/\/\/\/\//\/\/\. Perhaps it is a little lazy, meaning that it does not update as often as it should, but it stays in the green zone.
I have also changed the fuel filter. Sadly, I do not have tools to measure the gas pressure between the FPR and injectors. That is a nice to have tool and I plan to get it soon, but I do not have it now...
Any ideas on what is wrong ans the mixture is too lean?
The GS911 shows the Motronic version as 4.
What I did was to take the injectors and lambda probe for ultrasound cleaning. Also, I got myself an almost new cat, that I am going to replace.
I hope I can make the swap today and I will see how that goes...
I think you're using the wrong Cat Code Jumper (CCP) positions. The image you posted is one of the jumper positions used with an aftermarket EPROM.
Check out the factory CCP positions, and the Steptoe jumper. People use the Steptoe jumper positions of 30 and 87a for the R1150 with Motronic 2.4 ECU.
The factory Cat Code Plug jumper positions.
The jumper positions for an aftermarket Motronic EPROM chip. Possibly the BBPower chip.
The Steptoe jumper.
So I should be using a wire to connect 30 and 87, for the 2.4 motronic in a 1150 gsa for the original setup. Am I wrong?
You said you went from no jumper installed, to a jumper between 30 and 86. And when you installed that jumper, the bike didn't run right.
The previous post has links to nearly the jumper data there is on ADVrider.
No you don't have to use a wire. I suppose you could use a paperclip if you wanted to.
I was actually looking for a confirmation about what gets connected to what :)
There are a few jumper choices. Try them. At some level, jumper settings are like 'How many miles do you get out of this brand or tire?' threads.
1. No jumper, which you were using.
2. 30 and 86 which you tried but found it did not work.
3. The stock 1150 jumper setting, which you can try.
4. The Steptoe jumper, which you can try.
this might be helpful ( but im unsure why the photoshows 87 conntected to 87a?)
It turned out to be a bad stick coil. I almost started crying when I realized that. After all the work, it was a bad coil...
I had another 1200gs and I was able to swap the coils from that one. That is how I found out where the fault was...
Thanks all for all the help. A kick in the ass is one step fwd.
