Flashed BM3 stage 2 = high coolant temps ?

Recently flashed BM3 Stage 2 93 OTS and appear to have lost the aggressive cooling maps associated with Sport / Sport + settings. Pre-flash, coolant temps would drop 20+ F when switching from Comfort to Sport/Sport +, but no more. I did submit a ticket to PTF and they will look into it but....Anyone else observe this ?

I haven’t looked at this in real-time, but my logs here show the more aggressive cooling working with DSC off: https://f87.bimmerpost.com/forums/sh....php?t=1568593

Issue may, or may not, be specific to stage 2 93 OTS...

To be clear, my logs are not in Sport or Sport+.

S/S+ should trigger the same more aggressive cooling mode as DSC off, but just noting my logs are with DSC off.

I may have “jumped the gun”
Just road tested and aggressive cooling now appears to work for Sport/Sport +.
I now also have burbles I didn’t have yesterday, so maybe the ECU needs to cycle a couple of times ?.
