Any of that "Kirnberger" and "valloti 3" stuff is no use to you and even "Just intonation" is no use unless it relates to the key that your pipes are in... so the best advice is to use the Equal Temperament setting to get your A or D ( your preference... I use D) and tune the rest by ear or use the following off sets for your regulators, which will get you in the ballpark and then you pull the rest in by ear with your chanter:
offfsets from ET for Regulator notes:
D= 0 , F#= -14, G= -1, A= +1, B= -16 and C = -4 ......
sometimes I perfer to set things a wee bit closer to ET for B and F#... sometimes I prefer G and A slightly wider apart and sometimes I like the C a lot flater..... let your ear and your chanter tell you where this all should be.

Edit to add: of course the pipes are not like a concertina in that they will not keep very closely to the pitch standard with variances in temperature. Even when a set has been allowed to warm (or cool) to the room temperature before commencement , the chanter will rise in pitch after a few minutes of playing. So, any tuner that you choose to use should have the facility to infinately adjust its reference pitch so you can follow the pipes as they warm up.
Next point is that the chanter reed will rise in pitch more than the regulator reeds because it is in constant use , so some allowance might be called for when setting their pitch.... this is where the tuning pins come in to use , as they can be pulled out slightly to raise the regulator pitch as the chanter warms up and it gets sharper.
It's all about the Ears in the end
