In the interest of documenting what the Motronic does under various conditions, I've added a plot of fuel injection time and spark advance logged during the WOT runs I made to produce the torque curve posted above. (Below the advance/injection plot I've added a summary of the GS-911 data log for anyone interested in what's being collected. A typical test run has several thousand lines of data that gets imported to an excel spreadsheet. The first two columns of time and RPM are used to calculate acceleration, and from that torque and HP.) The conditions for the WOT runs were: shift the bike into fourth gear; running along at 1500 RPM; and then open the throttle fully until about 7000 RPM. Looking at the plots below a couple things stand out. On the injection time plot you can see the Motronic fire off 7 mS shots of fuel right away to get the acceleration going—very rich, and keep in mind that each injector fires twice per combustion cycle. Then from 2200 to 4000 RPM, still WOT, the pulses drop to about 5.8 mS—still rich but a little less. From 4000 RPM to 5500 the injection time lengthens to 7.5 mS which is nearly on continuously at 7000 RPM. Between 5500 and 7000 RPM the engine is putting out 70 - 94 HP so the Motronic is keeping the mixture very rich. AFR on my bike is in the low to mid 12s for these WOT runs; by comparison the stock setting is in the 13s. Looking at the Spark Advance plot, under the Wide Open Throttle conditions of this series of measurements, the Motronic is conservative with Spark Advance, holding it at 20 degrees or less until 5500 RPM. By comparison, under partial throttle cruising conditions the Spark Advance gets as high as 43 degrees.
