Yes, you can rewrite the ECU with another map, but I don't know if there is additional encryption from BMW.

But would you really want to spend £1600 on the BMWP remap, then another £850 on a DMS map, just to get an upgraded radiator fan and water radiator ??!!
Utterly pointless no? I will be retrofitting the additional water radiator once the car's back in action - it's not difficult at all and the parts aren't expensive. I'll forego the bigger radiator fan, because I'll already have two oil coolers and two water radiators...!
