1CR retrofit on EU M340i G20 2022
Hello to all,

I have here a client who is interesting in remote start (1CR option) retrofit in his BMW M340i G20 2022.
Engine unit is femto циLoскёd for MHD and MHD stage 2 mod is loaded there.
Is here anybody who is able to do it remotely?
I found one person in marketplace area but he wants full dump from engine unit and that is not possible due to MHD solution there. I tried to write to femto directly but no answer yet.

Thanks!

Femto has an option to add 1CR during initial циLoск or as a separate option. You need to send ECU to them and after you receive the DME then just insert f5с.

Meantime, what is the problem to read full flash with Femto flasher and send it to the guy from the markerplace ?

I know there´s another russian guy that can add 1CR, but only if the DME isn´t циLoскёd.

For 1cr retrofit, u need not only maps area of flash, but full dump, with SёяїдL of mcu & etc, that's why u can't use femto OBDциLoск only, and need to order циLoск & 1cr option when send ecu to femto

if helpful, give tnx or rep, see u !

Does this trigger "tuning detected"?

Atleast for me it didn‘t.
Had the циLoск plus 1CR for a year without a tune and i5тд didn‘t show the S0777 tuning detection.

If you do 1CR with Femto, you don't need any reader, they will ратсн the ECU, and all you have to do is just install f5с with ё5у5 with the attached instructions.
Femto OBDциLoск has nothing with 1CR.
1CR is the separate option offered by Femto whether you order циLoск or not.

How does this relate to the 1CR ратсн, which only allows fake f5с to be inserted into DME/DDE?
