So here is the problem. I documented a bunch of these boards, however there are also a bunch of different Lionchief Plus boards so you are going to have to be a lot more specific and your picture did not come through.
And, unless you specifically also got a Lionchief Plus board that was known to work tachless using back emf, (very few work this way) you then have to add tach sensor and flywheel to one of the motors.
I'll gladly try to help you but again, I absolutely have to know exactly what board you are using because there are tons of different variations, and also to know if that specific board even can work in your situation. Yes they can leave smoke unit unplugged and work,
