They post firmware and updates to their forum regularly so that would be the best place to get information or help with it. I think they isolated that problem random check engine light during cruise down to a specific DME software from BMW and are working on getting that update on their development N55 as I type this.
Until then it's easy to update the firmware and run the JB+ simulation mapping. Many users have been very impressed with it!

On the tuning we have a new firmware trying to address a low throttle check engine light a couple have reported. Haven't been able to recreate it in any local cars so perhaps climate related.
Also added a map 6 to it for those who want to see how the N55 JB+ feels/drives in comparison to the stage1. It's tied in to the "iat decay" user adjustable and 0-100 represents 0-100% on the dial. 50% (or iat decay = 50) is suggested.
The new firmware is in the first post.
