Description: Engine software on a turbocharged platform is far and away the most cost-effective upgrade to improving engine performance. Through optimization of control strategies and taking full advantage of the engine’s capabilities, immense power can be extracted without any additional modifications. The newest BMW’s powered by the latest B58 powerplant is no exception to this. In fact, supporting factory systems make the latest variant much more capable from the start compared to the engines previous iteration. The results are unmistakable… and enjoyable.

While increases in power via ECU upgrades in the marketplace can come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan’s calibrations are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning 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. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labeled as being the smoothest, factory-like solution in the marketplace.

Dinan’s ECU upgrades are offered in numerous configurations depending on your specific needs, desires or limitations. Whether you are limited to 91 pump gas, want to experience maximum performance on E85, or something in between, chances are Dinan has an option for you. At its core Dinan offers 2 base options; Stage 1 and Dinan +. The Dinan Stage 1 Performance Engine Software is designed for the B58 engine to yield maximum power (for a variety of different octanes), improve drivability, and remove the factory speed governor for unadulterated entertainment. The Dinan + variant of software offers these same features (albeit limited to 91/93 octane) but also carries the signature Dinan 4yr / 50k, factory matching new car warranty that the brand is synonymous with.

Features/Benefits (Stage 1):

• More Power:Max gains of 116 WHP / 136 lb-ft of torque over stock on E85. Consult the performance charts on the product page for additional octanes and data.
• 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.
• Access to numerous octane calibrations depending on your needs (91, 93, 100, 104 and E85). Switching between mappings would require a reflash at a Dinan authorized dealer.
• Full map rescaling for drivability from idle to wide-open throttle and everywhere in between.
• Optimized boost control, cam phasing, lamda targeting, fueling, airflow and temperature controls for maximum power output that is also safe and reliable.
• Retains all BMW factory engine safeguards and adds numerous additional safety protections.
• Top speed governor (VMAX) removed.
• Torque by gear strategies implemented for maximum power output and traction.
• Sport mode cooling that targets lower coolant temperatures added for optimum track effectiveness.
• Pedal feel improved to naturally align with the increased torque output.
• Sport gauges rescaled to reflect higher than stock power output.
• Remote start functionality (if equipped) completely retained. Digital key presence not required.

Features/Benefits (Dinan +):

• More Power: Max gains of 43 WHP / 62 lb-ft of torque over stock with 91 octane. Consult the performance charts on the product page for additional data.
• Dinan + performance software matches the factory new car warranty (4year / 50,000 mi) and is the warranty protection commonly associated with the Dinan brand.
• Limited to a single calibration (91).
• All other features from stage 1 above are shared with the Dinan + calibration.

Congrats on the release! I see there is an e85 option listed - is that tune running on an otherwise stock car?

Yes, outside of the tune the vehicle is stock (ie: stock cats, pumps, etc.).

Dinan_Engineering Do you have an eta for MY21 tune?

I do not. Its being worked on but trying to pinpoint timing on the reverse engineering / software side of things is next to impossible.

That makes sense, hopefully, you guys are close.

[lucasplagenza]

Do you guys recommend a spark plug upgrade for stage 1? Dinan_Engineering

[OffK]

Does remote start remain functional with your tune?

[Top Gon]

Does this work even with locked ECUs?

Tune is designed for stock components but successive stages may require a different plug or any number of other components to run correctly.

Should. Will get verification and respond back when able. Car currently being prepped for a track day and is not operational. =/

07/2020 and beyond build date vehicles / MY2021 vehicles with the new Bosch ECU's, are not supported.

This is huge for me, as this is the principal reason I haven't invested in an upgraded tune. I want my OEM remote start to work as it did before (i.e. not needing a to leave a keycard in my car full time), so very much looking forward to a response on this.

Side note, I wanted to check my DME version to see if my car would work with this tune and am having a hell of time trying to figure out how. I thought this would be a common question but my searches haven't gone anywhere. What's the best way to check what your DME version is? I'm assuming that the OTA updates are for iDrive only and do not affect the DME, correct? (Apologies for the newb questions)

[tarrant64]

Cannot wait for MY2021 to be figured out....

Either way - good work Dinan!

[Gdiddy23]

I checked out this product on the Dinan website and the stock dyno figures they show for this car is pretty insane. I know dynos aren't always 100% accurate but they recorded figures WELL above what BMW claims. I'm pretty sure the crank torque was like 450 or something

If the DME is unlocked then a dealer could flash it without sending the DME into Dinan. Or if the dealer happened to have their own unlocking tools on hand (not unheard of but rare) they could unlock and then flash without sending in the DME. However if the car has made an appearance at a dealership in the last year+ its safe to assume the car is locked. The number of unlocked cars in the field is going to be a very small number.

The M340i is closer a traditional M car (advertised crank numbers being closer to what the car actually makes at the wheel) in our testing. Not a bad thing as a consumer! Looking at some other competitors dynos in the marketplace our stock numbers are very similar to others in the marketplace so its not an outlier either. At the end of the day though no matter what the baseline says the most important metrics are the deltas which I think range from respectable to silly in the case of E85.

Does this remove the start stop function when idle ?
Also what would be needed to run e85? Wouldn’t I need sensors or something ?

We do not code out the start/stop function with the tune and nothing additional is needed to run E85.

I am waiting for my account to be verified but while I wait. I have a 2020 M340i. Engine started smoking, white smoke. Possibly oil. I had to add 1 qt. Car has 2k miles. Emergency error message came on starting battery failure and when I came out to the car, which was parked in a garage- not running. And started her up it said the engine was overheated. BMW said they have only seen this once before and may buy the car back. Has anyone had any issues similar to this??

So you’re interested in the Tune ?

[Darkace347]

Was interested in purchasing the Tune, was debating between the one with warranty and without. I noticed the one without a warranty has many more maps, if I chose an E85 map, but then later decide to flash it to the 93 map or even back to stock for that matter, do I have to ship my DME back out to you guys in order to reflash it to the different maps? The nearest dealer from me is about 1-2 hours, and doesn't seem practical if I wanted to switch maps like this.

Can you kindly clarify - for $499.00 US I can flash my car, run full E85, with no other mods and safely get 116 WHP gain? In an earlier response it was shared that it was simply a flash but this response mentions "other components" all good just trying to understand which options require something other than just recommended fuel and a flash
