Dinan has a long and storied past when it comes to engine tuning having introduced our first engine performance chip in the mid 80's — over 3 decades ago. From those early years with chips, followed by engine software and then to our own external control modules we have become experts in nearly every possible way to extract safe, reliable power from the factory powerplant. While we have long preferred the unheard of control and sophistication capable of being achieved from engine software, over the past 6 years that option was not one afforded to us. That changes now with the re-introduction to flash tuning for Dinan with the S55 engine. 

The first of the next generation of Dinan flash tunes, the S55 callibrations are held to the same principles of the past; performance, reliability and safety. Dinan performance engine software is so much more than just tuning up the turbo boost after all.  It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place.  Protecting your BMW while giving the most performance is the definition of "Performance Without Sacrifice". Drivetrain and engine components are analyzed for strength then the callibration is tested on the dyno and in the real world for durability and drivability.

This next generation of Dinan flash tunes does differ from the past however in that there are many different options to choose from depending on your needs or desires. Whether you want a warranted tune for 93 pump gas when under the factory warranty, an E85 performance tune for maximum performance when outside of the factory warranty, or something in between, chances are Dinan has an option for you.  

Features, Benefits & Requirements Specific to S55 "Dinan Stage 1" Performance Engine Software:

More Power: Max gains up to 146 HP / 155 lb-ft of torque over stock on the F87 M2C and 122 HP / 145 lb-ft of torque over stock on the F8x M3/M4 using E85. Detailed power data for 93 and E85 can be found listed at the top of the page or via the performance graphs located under the "PICTURES/VIDEO" tab. For performance data on other octanes you can download the charts at the links below.

       –  F8x M3 / M4  |  CRANK CHARTS  |  WHEEL CHARTS
+  Dinan Stage 1 performance software includes a limited lifetime warranty against defects in the software and provides free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty and are at the discretion of the place of install.
Access to numerous octane callibrations depending on your needs (91, 93, 100, 104, and E85). Switching between mappings would require a reflash at a Dinan authorized dealer. 
The Dinan Heat Exchanger (D780-0001A) or equivalent is highly recommended when running ANY of the Stage 1 maps. Without the heat exchanger installed the vehicle will tend to heat soak / derate under any meaningful load. Advertised gains as a result will not be able to be achieved.

Features and Benefits Common to All S55 Performance Engine Software Variants:

+  Full map rescaling for drivability from idle to wide open throttle and everywhere in between
+  Top speed governor removed
+  Retains all BMW factory engine damage safeguards
+  Torque gains drastically improve acceleration
+  No hesitation between shifts
+  Downloads through the OBD2 Port (See note at the bottom of the page about possible compatibility limitations)  
+  Hassle free operation — Install and enjoy


 

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. 

When I purchase a Stage 1 S55 flash do I only have access to one of the octane mappings?
When a Stage 1 S55 flash is purchased you obtain licenses for ALL the various octane maps. However, only one map can be loaded on the car at any given time so if you wish to use a different octane then what is initially loaded it would require a trip to your authorized Dinan dealer for a reflash. Labor / install charges to perform this service would be at the discretion of the dealer. We recommend loading the octane mapping that is most commonly used for the vehicle (91, 93 or E85 most likely) and only do a map change for special occurences such as a track day.    

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 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.

 

COMPATABILITY NOTICE - BOX CODES & JUNE 2019 FACTORY UPDATE


DME box code and bootloader information must be obtained from the vehicle to determine if a vehicle is flashable in its current state. In some cases we will need to create a file for your vehicle. This process could take several days and multiple dealer visits. 


Vehicles previously serviced or updated after June of 2019 may have received a DME bootloader update from BMW. This bootloader version will prevent the Dinan software upgrade from completing. DMEs with the updated bootloader must be removed from the vehicle, and sent to Dinan HQ to have the bootloader backdated. DMEs sent to Dinan for the backdating procedure will not be opened or physically modified in any way. Once the DME is returned to the dealer, they must still be flashed with the Dinan performance software through the OBDII port. If a previously backdated and flashed ECU is updated with the new bootloader, the above process will need to be repeated. Dinan will not pay labor under warranty to remove and reinstall ECUs that were previously backdated, and then updated by BMW or a third party.
