D-SPORT 4+

I wasn’t solely focused on the app as being a part of my buying decision. Dinan reputation, history with BMW and the affordability of the solution carried more weight for me. But when the app is so closely aligned with hardware functionality, Dinan customers, and its reputation as an innovator deserve better. If this was my first experience with them I can say that I would be hesitant to give them any additional chances. The DINANTRONICS Sport module is like the restaurant that has amazing food but unfortunately the app is the dirty unkept restroom. Clean it up Dinan and provide us with something befitting of the engineering heritage that provides the brand loyalty great organizations rely on.***App UI is buggy. Couldn’t get the gauge to ever appear even after a hard close of the app and uninstall/reinstall. Allowed me to change the driver settings but couldn’t refresh it. After identifying my vehicle type it wouldn’t accept and move to next screen. Had to hard close and start the process over. I didn’t have extremely high expectations of the app but they can’t align hardware functionality so closely to something so poorly developed.***

I only recommend to a certain extent. It’s a good starter tuner for anyone wanting to go the cheap route but definitely not the best either. I bought mine about a month ago and installed it but it’s had a few problems. For one, the boost gauge doesn’t work in the app, you can’t really feel any power difference and also the turbo lag for a base B38 F56 Mini is much worse than factory. Also, it threw a Drivetrain Malfunction warning due to the tune itself only because it adds boost. It doesn’t mess with anything else. This was a problem before with the Elite tuner apparently but that’s been resolved. What was going on was that the car wasn’t wanting to take the time because I’ve been told that it could have mixed numbers up in areas it shouldn’t have. Do I recommend it? Only if you’re looking at making your car quick on a budget, but if money isn’t an issue go with the Elite.

Dinan sells incredible upgrades that enhance BMWs and make them even better. Why on earth would they find it so hard to properly program IOS software and develop actual instructions for a better customer experience? This software does not do this product justice, and the poor execution of programming it and explaining it to Dinan customers would make most people think twice about purchasing this product over a similar tuner. The product seems to work well on my 228i. I just can’t always tell you why I select the functions I do, or why it sometimes allows me to change things, and other times I have to restart the software. The only plus is that once a mode is selected, it does not change on the tuner until another is accepted.
