hello, since we can use RR to tune m50 motronic ecu's (only 402 and its the most commun one) i told my self why not to "build" like a library of m50 original and tuned bins ,i spend a lot of time searching and collecting bins and it was suffering tbh so we wanna make it easy and more useful
we can share our experiences and some mods with this engine ( stroker , itb,...)

this is for 402 ECU

after the 402 THOOSE ARE FOR 403

M50 non vanos ECU 405

If any of these are non-stock, please remove them. See the forum posting rules.
Thanks

yes bro all thoose bins are stock if there's a non stock or modified one i will tell in the description or pm each other.if that's agains forum rules
having some modified bins for for exemple stroker or itb or cams ... will be good to exchange and giving each other idea and help

Thank you very much!! One question, how do I know the software that I have installed in the bosch control unit? I have the control unit 026120040 on a non-vanos m50b25 and the white label on the left has written 1748401 003 078. How can I find out the software? thank you.

you can find the software number writen on the eprom inside the ecu or by opening the bin file in a hex editor
its not a problem you can use any software number just always follow the ecu number
dont une 403 bin in 402 or 400 dont do that
