I have one in the post, any guides on what to do when running it in interrupt mode?

Reduce BCS DC Base by about 30% and fine tune based on logs. Reduce Load Error Correction BCS DC too to prevent oscillation from overcorrection. There is a Grimmspeed BCS tune for Speed6 I'll post the tables from that shortly.

I would have thought there would have been a way to set maximum bcsdc as well?

Max BCS DC is the lower of 100% or BCS DC Base lookup +10%.

So if you set base at 85% the max it will do is 95?

In theory. It does sometimes go a little over though.

I published a base 93/98 tune with Grimmspeed Interrupt BCS tables. You can copy the BCS DC Base and BCS DC Adjustment Load Target Correction tables from it.

It's a good starting point. You will want to log actual BCS DC and adjust the base table to match logged values in order to dial it in for your car.

any chance we will get one on the gen2 speed3 section?
