Dealer ecu flash?

bluekitty · Yesterday, 01:02 AM

Know how the 2025 m2 has more horse power than the 2024? Is it possible to have the dealer flash the ECU with the 2025 mapping on a 2024 and get the little extra power?

My car is starting to display a maintenance reminder for next month and I figured I'd ask here vs the dealer.

Anyway, I know I can do an aftermarket flash and get allot more hp out of the S58, but I don't want to void the warranty.

The delaer is mot able to flash you the 2025 software. Any kind of flash will lead to loss if warranty. You can flash the 2025 software by a coder as the original BMW files are used and the ecu is not locked for these files. kubax86 is a reliable source for such flashes.

There are a couple of threads here about the LCI flash. It’s not done by dealer. Can potentially cause warranty issues and I believe any OTA software updates will overwrite it
