Regarding single point wideband sensor, you don’t need to worry about front rear cylinder trims. The factory ECU map sends different trim values to the injectors already. IIRC the rear cylinders always run a bit richer than the fronts, to compensate for their warmer position and in the airflow. So if you use a single sensor you are adjusting both banks equally. To explain, let’s say at X rpm & Y throttle position the stock ECU sends front value 50 & rear value 55. Your internal or external (on dyno) AFR probe, decides you should have +5 added for the ideal AFR you have set the system for (13.2/1 for Dynojet, adjustable in RapidBike) , so all the injectors get a +5 signal added to the base ECU value, so the fronts now see 55 & the rears 60 ! So the offset trim values are maintained, regardless of which piggy back system you use. Hope me that makes sense.

Those things make bleeding brakes a breeze. Even my 5th gen took me no time at all a few weekends ago. Amazing tool!
