Bench Tune unlock required for BM3 tunes on my M2 Comp?

JoanLluch · 05-17-2022, 06:50 AM

I'm going to replace my M4 F82 by a M2 competition F86. The manufacturing date of the M2 is August 2020.

As I am now used to the M4 engine behaviour, I want to get about the same feeling on the M2, so I plan to apply a BM3 Stage CS or Stage CS+ tune to the M2 car.

I am not going for more aggressive tunes because I will be driving the car daily and plan to do a lot of mileage with it. So I just want the engine to pull as it normally should on the upper rev range

Question. Do I need to dismantle the ECU and send it for bench unlock with this car before I can flash my desired tune into it, or can that be avoided?

[EDIT] Sorry, I realised this subject is best on the general discussions, so I just posted the same there. Please ignore here

August probably means no bench unlock will work, sorry.
