So if we are running now and no problems, then it will not need to be programmed and be a plug and play.

So this could be a mandatory preventative maintenance.
all depending on the cost.
but completly understand on wanting to get the finish product completely done before you figure the price and let us know.
I am sure several are curious about what price range you are shooting for.
If it would be cost effective enough for a preventative maintenance, or be more in the range of holding off till it is needed.

Sounds like what you have a generation 1 atm
And in the 6-12 months a gen 2

Definitely time consuming soldering all the wires, once you have your board set up how you want and can etch it and much less wires to solder

Unless you have a electronics college close and have the class practice there soldering skills

TY for your work.
