R1150GSA Pinging

Thanks

The ecu from 1100 rs is MA 2.2 (1993 model). But i think that the rs has not catalytic.

Can i use it for my catalytic gs1100 ?

Not as a plug-n-play swap, the connector pinouts are different. It's possible though. Some number of the 35 pins in the 1100 ECU connector must be relocated to match the 1150 ECU.

Thanks. Anyone who has the SCHEMATICS diagram from both ECU ?

It's not.
It's just the same couple of people who always have the problems.

Way to empathize, Neil.

I hear you.

Pinging may not be much of an on-going problem but there seem to be lots of lingering effects of lean-running in the Oilhead fleet. It seems that most owners accept them "just the way they are". My personal favorite symptoms are, "keep the RPMs up, Oilheads love 4-5000RPM", or " ... rarely in 6th gear below 70". With as little as 3-4% more fuel, the Boxer motor is transformed.

Although Lamda shifters can be bought for $160 (Innovate Motorsports LC-1), when someone makes a Nightrider-type Lambda-shifter, then I think there'll be a wave of interest in what these devices can do. Here's a good comparison table: comparison of different lambda settings.

That 'lambda shifter' is fantasy.

I was referring to the Nightrider 'level shifter' piece you mentioned. Not your LC-1.

Hello again.

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 :
