Thank you for posting your data and findings. No doubt the 50e has some performance left on the table given the odd detuning from bmw.

Any chance you have logged some 1/4 mile or 60-130 with stock vs the device? The later might be difficult if I’m remembering correctly that they limit these cars to 130

Any exhaust mods to this beast?

Not mine. Just a tuning box. Testing again today

Last week I took my tuning module off and plugged in as stock and tested. In summary, I found a .38 average improvement in the 0-60 times and .47 improvement in 30-80mph times while plugged into the tuning box vs stock. I have no idea what dyno results would be

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.
