Need Help on TBW
So, lets say that the increasing circuit has a range of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and the decreasing circuit has a range of 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, at mid throttle both would read 5, at idle one would read 0 and the other would read 10, and at wide open throttle it would be the opposite of 10 and 0. So if the computer reads 10 and 1 or 1 and 8 (or any other mismatch), it can force a reduction in power. If I understand the "why", this is done so that the system won't allow the engine to rev up because it mistakenly thought you wanted wide open throttle when you were at idle or mid throttle. Its a "safety" to keep the bike from taking off when you don't intend for it to.
Most people probably are not having a problem when they solder the wires because the connections are good enough so the system still reads the values within the allowed margin of error so everything works like it should. But sometimes you might have a problem if you have a bad connection (or two), and that may result in what your friend was trying to express.
I'm sure that someone much more knowledgeable of the TBW system can correct and clarify what my feeble (and ignorant) attempt at an explanation is trying to say.
Good luck with it, I hope you are back on the road soon!
