I’ve been asked if this will do fuel mapping and stage two mods. No, it doesn’t replace a $2k programmable ecu with wideband. It does allow you to have fun adding a bit more kick to your bmw. Product works perfect for the price. ### 5/5 — AMAZING *2025-08-16, version 2.0* Installed the tune on my bmw (very easy) and downloaded the app. App works great and very noticeable results ### 1/5 — Not compatible with iPhone 14 or newer *2025-04-16, version 1.9* Dinan is working on a newer version of this app but for now it is not able to connect. ### 1/5 — App is complete JUNK! *2023-02-17, version 1.8* Wow, if dinan doesn’t give any importance on its app, what does it do with its tunes? ### 1/5 — James Brady App Experience *2023-01-22, version 1.8* Trash at best! As I read reviews on multiple distributors websites and forums, this app is in disparate need of an update for several years now! It takes away from the full experience of the unit. For most, they have bluetooth connection issues like myself on current ios and android devices. Where I come from that’s called not getting everything you paid for! Very disappointing Dinan, we as consumers expect more from a company of your magnitude and longevity to just turn away and ignore this and do nothing. Especially when there’s so many other developing companies with a similar unit! ### 5/5 — Simple and works *2022-08-11, version 1.8* I don’t understand why this app gets so many bad reviews, perhaps it’s because they are slow to update the app when there is an iOS update? It’s a simple way to get a few extra horsepower and changing the map is very easy I don’t really have any complaints. Safe on the car never any check engine lights much safer than MHD tuner which I have had in the past and made my engine run poorly. ### 1/5 — Dinan should be ashamed honestly *2022-07-21, version 1.8* You’d think a company so reputable and so amazing would not let some crappy app stop their customers but it’s yet to be addressed or even remotely fixed , the app does not show a boost gauge for one, two it does not give you 30-50 additional horsepower , so all in all the app is garbage and dinan doesn’t seem to care to address the hundreds of horrible reviews about that , and they false advertise to get you to spend 300 bucks. I’ve emailed dinan several times and to my not so shocked state…. No reply . You’re leading your company towards rock bottom guys.. fix the app or make changes for god sake ### 1/5 — Absolutely horrid app *2022-07-15, version 1.8* Bought a Dinan Tuner for my F10. App doesn't even recognize the tuner and support basically said your iPhone might not be compatible. Thanks. ### 1/5 — Changes Tune on its own! FIX THIS!!!!!!!!! *2022-06-07, version 1.8* The application changes tunes on its own to Valet mode. The application does not let the driver know what tune they are in. Dinan does not seem to care what the application does as long as they sell products to the customers. As long as they fleece the customers. I will be reaching out to the AG office to report the company for selling worthless products. I have filed a BBB complaint as well. Dinan needs to know if they sell products to customers they must sell products that actually work or they will be reported. ## Frequently asked questions about D ### What does the D-SPORT app do?
