With the right BMW i3 coding, it's easy to recode your i3 REx and flexibly activate battery charge hold mode. And to keep you driving even longer, get a gas tank capacity upgrade. It's possible to hack your BMW i3 for more driving range, as well as some other cool features.

I recently bought an older i3 BEV as my around-town errand car. Being a 2014 with a well used 60Ah battery, its range isn't great, but well within my needs. Nevertheless, as an embedded electronics nerd, I thought it might be fun to try and boost the range by hacking up a custom range.

Check out our i3 REx coding, which will extend your BMW's range by increasing your gas tank capacity reading and unlocking "hold battery charge" mode. The most obvious change that NEEDS to happen on all Rex BMW i3s is adding the extra fuel capacity and enabling the range extender menu. These 2 options extend the distance and speed you can travel.

What is the BMW i3 range extender? As modern electric cars promise hundreds of miles on a single charge, it's easy to forget that the original i3 would give out after only 81 miles.
