Dinan's new Plus Performance ECU flash software is being rolled out with the S55 engine platform first. That means it applies to the BMW F80 M3, F82 M4, and F87 M2 Competition.

No doubt some fanboy of tuning company X will point out there are tune only S55's making more power and that is true. That same fanboy likely will not bring up tuner X does not match the factory warranty and tends to disappear when things go wrong when pushing limits or releasing tunes way too early (which happens more often than you think).
Dinan is taking an approach very similar to that of APR which is high quality software and products that go through rigorous testing and engineering. This is a big difference compared to your typical social media tuner stating they are making huge numbers while testing tunes on customer cars and hoping for the best.

DINAN S55 ENGINE PERFORMANCE SOFTWARE FAQ:
I already own a DINANTRONICS Elite kit for the S55 engine, can I switch to the flash?
Yes, you can trade in your existing DINANTRONICS kit and qualify for a warrantied tune (balance of the factory matching 4yr/50 k warranty) upgrade for only $149.95. If you are already out of warranty or simply want more power you can opt to switch to the full stage 1 options (no factory matching warranty) without any associated upgrade fee. Pricing listed is dependent on trade-in of registered, first-hand units. Used, second-hand units do not qualify.
I have the Dinan + tune but want more. What are my options?
Dinan+ users can upgrade to the Dinan +HE variant at no charge for more power while retaining the Dinan factory matching warranty provided a Heat Exchanger is purchased and installed as well. For those that want even more power you can opt to switch to the full Stage 1 tunes, taking advantage of more aggressive mapping geared for race fuels, at no additional cost. Switching to these mappings however will immediately cease any factory matching warranty obligation. For all of these scenarios, labor and/or install dealer fees still apply.
MPG with Performance Software on a turbo car?
This is the beauty of a turbo engine. When the engine is not in boost (below about 3K rpm) it is sipping gas like a small non-turbo engine would. It is only in higher boost levels that more fuel is used. It all depends on your right foot, if you drive gently the car will use the same or slightly more gas than stock and if you drive it at wide open it will use more.
I do not live near a Dinan Dealer can I still purchase Performance Software?
At this time Dinan S55 Engine Performance Software must be installed through one of our authorized dealers. Our dealer list is constantly expanding however so check out the dealer locator often at https://www.dinancars.com/authorized-dealers/ to make sure a new dealer has not begun servicing your area.
Will Dinan parts be covered under my extended/CPO warranty through BMW?
The Dinan warranty matches the new car 4 year / 50,000 mi warranty but does not cover any extended or CPO warranties.
Will stock parts hold up to the added power gained from Performance Software?
Dinan performance engine software is not designed to push your vehicle to the point of potential failure. Part of our R&D process is scrutinizing every component for the ability to handle the extra power added to the system. We work very hard engineering our products to work within the limits of the engine components, and feel as confident about our products as BMW does about theirs.However, frequently tracked or aggressively driven vehicles should shorten maintenance intervals to account for wear and accelerated fluid breakdown.
Can I flash my vehicle back to the stock tune?
Yes, you have the ability to flash the vehicle back to stock but the process would need to be completed by a dealer. There is no cost to do so from Dinan but you would potentially be subject to dealer labor rates to perform the service.
After installing Dinan Performance Software who can service my BMW?
Anyone.
What if I am not happy with my Dinan Engine Performance Software purchase? Is there a return window?
All Dinan engine software include a 30-day money back guarantee with no questions asked. If for any reason the owner is dissatisfied with the Dinan engine software, they may return to the place of purchase for a full refund, provided they are within the 30 day period from the time of the initial purchase. Labor or shipping charges are not included in the guarantee and are at the discretion of the place of install.
