F6B where's the weight?

Interesting concept. I always match rpm to road speed when downshifting, car or bike. I don't understand why it would make a difference that the engine is fuel injected? Why is the ECU "confused"? You need to raise the rpm, so you use the throttle (the "blip").

The ECU reads the data from various sensors to determine how much fuel the injectors get(injector pulse width) like the TPS (Throttle Position Sensor) or where the ing. timing should be for the load on the engine, as well as the MAP and KNOCK sensors, all which tell the ECU what is going on and what the engine needs at that time. By blipping the throttle the data sent to the ECU is wrong for what is going to happen next...slow down or stop, so the ECU thinks you are accelerating and gives more fuel than needed, changes timing agin thinking it is going to accelerate. If you are running open or more free flowing exhaust pipes you will more than likely hear decel popping which blipping the throttle exacerbates.
Now on a carbed engine decell blipping was to clear the engine as the vacuum will suck in more fuel and can cause a stumble if you were to suddenly accelerate. There is no need to blip a EFI engine, but old habits are sometime hard to change.

As to matching the engine RPM to the trans gear speeds.... Do you let the engine come to an idle before each down shift? Of course not, the engine is turning enough RPM under normal riding conditions for a nice downshift, try downshifting without blipping the throttle and you will see the F6B as well as all Goldwings will downshift perfectly.
