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.
