Well I have covered about 50 miles with the new settings, maybe 30 on the open road and 20 around cities. What an improvement! Especially on pavements dodging old people.
Before the chair would lunge around, then you would over correct trying not to hit anything. Now the control is much more direct, just as important it also stops when you stop turning, it also feels a lot smoother, it goes where you point it without the chair dancing around like it's possessed. Before the braking was insane, when I moved the joystick back even a little it would brake so hard the wheels could lock. Braking is a lot smoother now and you can still get an emergency stop by pulling back on the joystick. I can still go up and down curbs and I have never met a ramp that I could not go up or down.
I have not had any cutouts or overheating and the batteries seem to be holding up like normal.
Thanks for your help Burgerman, I am in your debt.

Have you got a voltage leak / connection to the chairs frame? ... It might be worth a check with a multimeter.
IF you have , then try disconnecting components till it vanishes.

OK. Here are what I got today.
(+) … (-) → 25.54V expected
(+) … Chasis →25.54V unexpected would expect almost nothing or at least less than batt voltage. What was minus to frame? Should be the same as plus to frame...
(-) … Chasis →31KΩ lower than expected, what was PLUS to frame??? Should be identical really. This may be a motor leakage to the casing.

While measuring this resistance to frame, from plus/minus you can try the following. Disconnect the right motor connector at the motor end. And then the left. Does the resistance of your suspected bad motor make a big difference? Compared to the other one?
Then on the MOTOR with the power plug disconnected. Measure resistance from each motor sensor wire to the metal case. Should also be extremely high.
