The initial round of tests of lambda-shifting that I made on the Motronics and BMSK ECUs covered a broad range of motorcycles. So far the list includes: R1100GS/RT, R1150GS/RT, R1200GS/GSA, F800S/ST/GS, F700GS, F650GS and recently a Husky TR650. The vast majority of those tests were made using the Innovate Motorsports LC-1 Wideband O2 sensor, which has a simulated Narrowband Output. The measurements and results can be found here, 2004 R1150GS/RT R1200GS/GSA Wideband O2 Sensor Project Part I, and on other sites. Although I began the thread as a place to post tests that I made on the LC-1, it seems that product support questions crept in, in violation of ADVrider's strict policy against that sort of thing. As a result the thread was archived to the VENDOR forum. Here in part II of the research and measurements, we all need to respect the spirit of ADVrider's GSBoxer thread. Therefore if you have a question about the AF-XIED for BMW, please ask it here: BMW-AF-XIED by Nightrider. If specific questions do get asked HERE about that product, I won't be able to answer them and I'll ask the moderators to move those questions to the Vendor thread. Lastly, GSBoxers is about the GS and GSA boxer motorcycles. Therefore, if you have questions about your RT, I will answer them only in the context of the GS products. The moderators have been clear about RT contamination, they don't want to see it. In that spirit, I will be asking colleagues with R1150GSs and R1200GSs to make any measurements needed to support Motronic and BMSK fueling questions. The next post, later today or tomorrow, will be about measurements that were recently made on a 2001 single-spark R1150GS. These measurements clearly show the Motronic MA 2.4 learning about fueling and adapting the Long Term Fuel trims. Because the Motronic MA 2.2 and 2.4 lack the computing power to report short and longterm fuel trims, many hold to the belief that those fuel trims don't exist and therefore that the Motronic is unable to learn about mixture. I think you'll find the upcoming data more clear and convincing that the far more technical entry I made here: Motronic MA 2.4 Mixture Learning and Adaptation, that runs for a few pages. Please join me in supporting the moderators by sticking to the mission of this thread.
