Thanks for the data that means the R1200 pumps 3L per minute, about 50% more fuel per minute as the R1150/R1100 which is 2L per min.

Your data looks great, no negative Engine Load numbers, as with the other Camhead I've studied. A further observation, before you replaced the pump, your Multiplicative trim was about 7-10% high meaning the BMSK learned it had to add fuel to get you to a stoic ratio (due to low pump pressure I bet). Since you've reset the adaptives and replace the pump the numbers look like -3% to 0% meaning the pump is giving the injectors about the amount of fuel they need. Other aspects of engine performance can affect the adaptives but they fell about 10%, which points to the fuel pump replacement. Ride for 1000 miles and PM me with some new data and lets see how they look.

Thanks for the data that means the R1200 pumps 3L per minute, about twice as much fuel per minute as the R1150/R1100 which is 2L per min.

Thanks for all the help!
