Don't waste your time. There's virtually no advantage in using a torque sensor rather than a cadence sensor if you have a bike with a hub-motor. In fact, it can bring substantial disadvantages. It's the controller that regulates the power to the motor, and if you simply changed the cadence sensor for a torque sensor, you'd get power when you didn't want it. A torque sensor needs a special controller with the right software. The retro-fit ones I tried were pretty bad.

The more expensive bikes combine the torque sensor with a cadence sensor to get a decent power algorithm. Even then, some of them have power algorithms that you might find unsuitable. Most work on the basis of multiplying your torque, but that doesn't suit people with weak legs or who have problems with stamina. You can see the scenario, where their legs get tired going up a steep hill, then they can't get enough power from the motor, so everything ends up fizzling out, and they end up pushing.

Ok, but this is the deal, I have got a rear hub motor with integrated torque sensor and with pas sensor at the crank, and of course de controller that fits it, and it has a huge difference with the bikes that just use PAS sensor.

No I´m looking to switch into a front motor, because I´m 2m tall and almost 100kg, so with the battery at the rear rack, plus motor, plus me, the rear wheel is not having a great time.

Thats why I´m looking for someone who has tried the Bafanga bb torque sensor.
