1. Super easy to install. I'm not much a DIY'er but with a couple YouTube videos it was a piece of cake.
2. Blue tooth adapter with iOS App = A+. Real time feed with the gauges is a very cool, and the ability to change maps and settings on the fly is impressive.
3. Power (even in Map 1) is serious. Instant power all through the bands; seamless shifting.
4. Ability to uninstall the tune when going in for a service; 👌🏽
Conclusion: If you're looking for a piggy back tune, this seems to be a great option. Very happy with the investment so far.

I also have a JB4 installed on my M340 as well. Love it but there are a few issues you may run into. Seems as if Jb4 isn’t as optimized for the M340 B58’s yet. On Map 5 with a E30 mix it’s a gamble whether the car will function properly or not. Throws a drivetrain malfunction for me and seems to be running quite lean most of the time. Map 1 & 2 with 91 pump are solid though, never had a issue. Only run into issues whenever I push it a little. Love it regardless highly recommend it but just give it time so they figure some stuff out. Let me know if you run into any similar issues. |
Thanks, I'll keep that in mind as I get more experience with the available map settings.
Map 1 & 2 with 93 octane have been flawless so far. As a daily driver, it's likely I won't be out of these two all that much.
