Description: The S58 motor, even early in its production life, is known as an immensely capable engine delivering power well beyond its advertised levels. This is typical of most modern-day BMW M platforms. What is not typical however is the copious amounts of headroom left on the table for entities like Dinan to take advantage of. Approaching, and/or exceeding, maximum gains of 100 WHP/TQ with pump gas and no additional modifications for an inline-6 is a dream that has become a reality.

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 96 WHP / 126 lb-ft of torque over stock on 93 octane and 137 WHP / 149 lb-ft of torque over stock on E85. Consult the performance charts 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.
• Improved 0-60 and 1/4 mile times.

Features/Benefits (Dinan +):

• More Power: Max gains of 54 WHP / 77 lb-ft of torque over stock with 91 octane. Consult the performance charts 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.

Couple of questions -

1) Is the main difference between the 91 tune of the Stage 1 and the Dinan+ the warranty? Or are the power levels different between them as well?
2) When do you expect to have CARB approval on these?

[BMWFanatic2008]

Wow, great price considering Dinan matches factory warranty. When are you planning to make this available for 2021+?

[Soylent]

What do mean E85? E30, E40?

[stoked335d]

Dinan, This beast is a bit laggy on low end torque for street driving. Willing to sacrifice peak hp for more torque gains below 3K RPM please.
Your dyno numbers for stock are 619hp/523lb-ft torque at crank vs 503hp/442lb-ft advertised.

[allinon72]

Interesting. That price with warranty is hard to justify but it is a unique option.

1. Stage 1 (91) and Dinan + are identical in every way. The only difference is Dinan+ carries the 4yr/50k factory matching new car warranty.
2. Timetables on CARB processes are impossible to guesstimate. We have had applications in for years in some cases and then some things like the X3M intake get approved within a couple months. We emissions test to federal/EPA standards as we can do that ourselves with our in-house emissions dyno cell and then submit all that test data along with the submission to CARB. In theory that should make the process go faster but in the end all I can say is its in the submission process like we do with all of our products that can affect emissions. When it peaks its head out the other side of the process the website, etc will be updated to reflect it.

E85 fuel is Ethanol/Gasoline mix where 51% to 83% of the mixture is ethanol (typically E60-E85 is what is all lumped together as E85). We only tune for E85 directly and dont get into blends (E30/E40/etc) as E85 can be gotten at the pump and is regulated to be within proper mixes (ranges quite a bit by season/location but regulated nonetheless).

As typical with M cars -- the X3M is putting down advertised crank numbers at the wheels -- and then some. This one was a bit more lively than most but it was not all that suprising given history.

If you are interested in a factory matching warranty -- Dinan+ offers the best value there, by far, between all the known entities that do offer that type of option at least.

21+ MY DME encryption is still being worked on. When a breakthrough will occur on that front is anyones guess. All of us on the sales/marketing side hope its soon but who knows. In the meantime we just watch the software guys toil away downstairs and occasionally knock on the glass to make sure they have eaten, gone outside for some vitamin D, stretched, etc.

The low end on these vehicles is due to the turbo sizing. No tuning it going to improve the low end substantially. The trade off this the strong pull to 7200rpm redline. Can't have both.

Is it coming to the UK?

Haven't specifically looked at a Euro file but I have put in a request to the software/calibration team to take a look. That said, the DME would still need to be shipped to us here in the US before going back to the UK if it can be flashed. Calibration said throwing together a quick file to ensure there are no surprises before sending in a ECU shouldnt be a problem thoughand they would let me know their findings once they have taken a look. Will update the thread when I hear back.

UPDATE: Pulled the codes we have that are ROW and the vast majority of them appear nearly identical so porting them shouldnt be an issue. However, there is one that is more closely related to the M3 than the other X3M's which may pose some problems - wouldn't know for sure until it is attempted though. Which variant you have specifically is anyones guess until the DME is read/extracted but I would say the chances are definitely more favorable then unfavorable.

Are they the same size on the G80? I've never heard of anyone complaining that the G80 lacks low end, so if the turbos are the same size as f97, that tells me it's in the tuning.

I'm aware of what E85 is. Maybe I wasn't clear in my question. So what you are saying is that the numbers you posted are on a full tank of E85 with no 91 mixed in?

[Kevin_The_Clean1]

Since I live in a part of northern CA where only 91 is readily available (rarely is 93 offered in this area), I'm assuming the DINAN + would be the ideal kit for me. And I like the sport cooling mode a lot as well.

(1.) Does the stock DME parameters allow for 91-93 octane fluctuations / blends? And would the 91 only (DINAN +) prevent me from maximizing the natural benefits of the occasional 93 pumps when I find them / stumble upon them... ?

(2.) Would the fans & other cooling gear be kicking on sooner, even in normal driving conditions? Or only during WOT / highly spirited driving... ?

(3.) The DINAN + kit says it add 54 WHP / 77 lb-ft of torque over stock with 91 octane. But the graph clearly shows only 11 WHP / 72 lb-ft gains? Am I looking at things wrong or doing my math incorrectly... ?

Ahhh-- straight E85 from the pump. No blends.

1. Dinan + and Dinan Stage 1 (91) are identical. Only difference is he matching warranty. So if you didnt care about the warranty you can save a few bucks. As far as running 93 (or above) on a 91 octane file it will run fine. The car will naturally adjust timing to compensate a bit for the extra fuel yielding a bit more power. Won't be up to the levels of the specifically tuned for 93 (or above) files but there is some latitude in that regard. What you don't want to do is the other way around and run a lesser octane on a file designed for a higher one. Thats where you get into trouble.

2. Depends on driving mode -- in sport mode they will be running much more often. In the lesser modes they will be running per design from BMW when temperatures reach certain thresholds. This will happen more often obviously when spirited driving however.

3. Max gains vs. peak gains. The 54 / 77 numbers are maximum gains regardless of point in the power chart. 11 / 72 would be at peak. On the product page you can go down to the specs sub-section and you will see both metrics listed there (albeit in crank for easy comparison to stock ratings).

Is there a technical limitation as to why you don't offer the Stage 1 with all of the octane maps so that the user can easily change them?

Moving a car that is quite a bit lighter then a SUV (800#s) is going to feel quite a bit different.

Don't currently have a delivery system for the end user.

Disagree, not when we are talking torque figures in the mid 400s and HP figures above 500.

[richard in NC]

A question:
Would the tune work on a 2020 non-comp?
Would I see the same max numbers as a comp, or at least similar gains (90+ hp from the non-comp 470.

I'm also mostly interested in improved low end torque. It looks like there's at least some gain by 2500 RPM.

PS I'd be using the 93 octane settings....

Moving 700#s of less mass with the same engine is not going to feel more powerful and torquey? I think you are hunting for something that is not there. Not going to magically command/tune a larger turbo that is designed for mid range and top end pull, to spool faster and deliver low end power/torque. Trade in for a different x3 then the m if you want bottom end feel.

Of course it will feel more powerful. Just not to the extent that, given equal hardware, people would complain about the lack of low end on the X3M and not a peep about the G80.
