Sure, the Dinan has problems and so do the JB4 and NM module. It's not really Dinan's fault the guy took his car to a non-Dinan certified dealer instead of contacting Dinan or at least touching base with both Mini AND Dinan. I got a CEL with the code P12A9 code and the first thing I did after getting home was to install the bypass and contact Dinan. That's just common sense if you're using a piggyback tuning box. You're bound to run into problems when modding so you need to at least have a basic knowledge of troubleshooting problems when they arise. It sucks that the guy had a problem with his Dinan, one that sounds more serious than the one I had with mine, but his sole experience isn't a good representation of Dinan just as mine on its own isn't either. There are way more people that never had an issue running a piggyback but you rarely hear about them because people don't normally post on forums "I made X modification 3 years ago and it's still working great!" You usually just hear about the times when someone runs into an issue.

 

I have had the NM on my 2016 JCW for over 3 years and 35,000 + miles with no issues.

 

JB4 and Dinan are both available for the F54. I was using a JB4 piggyback with some success prior to getting a tune. Honestly, a tune is a solid option for the F54 -- and paired with a catless or sportscat downpipe and larger intercooler (be aware, some intercoolers won't fit nicely in the F54 body due to possible differences in the crash bar / slam panel), the F54 can be really zippy to scoot around in.

I would suggest a piggyback tuner like the JB4 as a first option. You'll get some good oomph out it.
