Default Auto final drive swap - coding required? - 08-21-2018, 02:51 AM

Hi All, new JB4 user here from the UK with and auto m140i.

I'm looking into fitting a 3.077 diff when I have an LSD installed and I understand that it requires some coding to avoid transmission errors, though information on the topic is very scarce.

I found a user on BabyBMW that had done the conversion and have PMíd him, but itís a while since his last visit.

A chap in the UK that does lots of LSD swaps is also on the case for me, trying to find out whatís needed as he also knows of one thatís been done.

Any nudges in the right direction gratefully received!

Cheers, Matt

How are you correcting the speedo and odometer? That’s going to take more than coding. It’s going to need some sort of flash.

The speedo and therefore odometer will read wheel speed so will be unaffected.
