If we are talking 2015 -2016 Kawasaki Versys 650, seems a few people had a quick look at my post and that was it. More detail of why the booster plug may work but the flash available for the 2015 & 2016 is far superior

I copied my post from another forum and edited it. This was my question:
My question, is the intake air temperature directly related to fuel mixture & timing, as that is what it seems as to booster plugs. And a answer
Yes, there's an ambient condition sensor that will richen the fuel as needed with outside cooler temps. That's what the booster plug is doing. the problem is that there is a weird fueling strategy in the ecu that has both cylinders operating with different fuel charts, and they switch, where one is richer and the other leaner for a couple thousand rpm, and then they reverse. .. so in that area ( below 4000 RPM where the problem exists) the booster plug would be adding fuel... not a strategy I think is viable.
So my take on this topic, adding a booster plug, doesn't involve removing your ECU , is possibly cheaper and easily reversed if you decide to return to OEM. Since I have owned a 2007 and adjusted the TPS and now own a 2015 and have had the ECU flashed
, I can honestly say it is like a new bike. Several comments in the other thread I started mentioned no one riding in the below 4000 RPM range, speaking for myself, many small towns I pass through have 60 KM/HR speed limits, the highway speeds into and out of are typically 80 to 90 KM/HR. I can now ride down to 2500 RPM at 60 KM/HR in 6th gear and accelerate back up to 80 KM/HR , without changing gear
Also gone is the abrupt off throttle engine braking and low RPM snatchy throttle response.
