2020 vs 2021+ tune cost difference

Dutt1113 · 12-28-2023, 02:48 PM

Does anyone know the reason for the huge cost difference in the tunes for 2020 vs 2021 M850? The tunes for builds up to 6/2020 can be had for $1000 or below. I keep reading that the builds for 6/2020+/2021 and up are not possible, yet I've seen some tuners like Eurocharged and DME Tuning show tunes available for 2021+, but they are $1999 and $3799 respectively. Both 2020 and 2021 tunes show around the same power of about 670hp, but the cost difference is huge. Is it a special process vs 2020's to flash the ECUs or is it just the demand vs low supply of tuners that have figured it out for the 2021 ECUs?

It is because the new ECM's need to be benched unlocked in the EU before they can be tuned at all. So cost is added into the shipping and work there and back for tuning. Like having to pay twice sadly...

For a 2021 and up, that seems like it could take weeks to get the ecu shipped to the EU and back for a flash. For a 2021 I'd rather just get a jb4 until a local flash or remote flash can be done. I'll probably end up getting a 2020 anyway which I guess wouldn't matter in that case.
