castaway_2054 wrote I've had the bluespark tuning module in my 2025 X5 50e for about a week now. I have it on the default "C" setting and the difference in driving experience is quite stark. The car is much more responsive and acceleration seems to come effortlessly. Engine runs very smoothly overall the car is a pleasure to drive. Honestly I feel like this is how the stock tuning should have been to begin with.
I'll try the higher settings once I have the recommended 200 miles on the C setting.
Agreed. I moved it up to E9 after 200 miles and picked up .50 second in a 30-80 sprint over stock. Remarkable performance gain with just a box. Best I could do 0-60 was 3.66 (1 ft roll) or 4.04 standing. Stock was 4.15 1 ft roll and 4.44 standing and all this using a reliable draggy. Launch control used in all sprints. Oh and btw my best 1/8 mile was 7.87 fwiw. No place near me for safe quarters.
