Description: Some of the world's most potent sedans and SUVs to begin with, the F90 M5 and F95 X5M now have the ability to go beyond formidable and to levels of outright domination in their respective classes. With max gains on pump gas nearing +130 WHP and +200 lb-ft of torque courtesy of Dinan Stage 1 software the battle for runner-up in each respective class is the only question.

Those are garish gains on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive feat. One that will be sure to result in a very enthusiastic grin. Utilize race gas or E85 and the gains jump yet another factor of fun -- a mind boggling +198-226 WHP and +190-207 lb-ft of torque to be exact.

While increases in power at this scale typically 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 labelled as being the smoothest, factory-like solution in the marketplace.

Features/Benefits (Stage 1):

• More Power: Max gains ranging from 122-130 WHP / 190-198 lb-ft of torque over stock with 93 octane and 198-226 WHP / 190-207 lb-ft of torque on E85. Consult the performance charts for additional octanes and/or detailed data on specific vehicle variants.
• 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 ranging from 96-104 WHP / 148-157 lb-ft of torque over stock with 91 octane. Consult the performance charts for detailed data on specific vehicle variants.
• 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.

Looks promising. Thanks for the write up!

Hello Dinan,
When I purchased a tune for my F10 M5 the tuner gave me access to detailed instructions for the DME removal and replacement procedures. For those of us who would rather do it ourselves is that something that you will provide?

Really not much to it on the newer engines. Remove the side engine/DME covers. Unplug the connectors. Pull up. DME removed. Repeat on other side/other DME.

Other then making sure the car is completely powered down and having the keyfob out of range so the car doesnt power up thats about it.

The X5M/X6M is a bit more involved since the bracing gets in the way a bit but its not really any more "difficult" per se-- just less room to work with.

I hadn’t even looked at them until considering your tune. No more water cooling? I like this F90 version more and more. So many little refinements to the car from the F10 that make it a better package. You don’t recommend disconnecting the battery before removing the DMEs?

good job guys !

Still has air to water intercoolers. DME location is just not as buried is all. Pretty much all of the newer engines (B series primarily) have made them incredibly accessible unlike the past.

As far as disconnecting the battery -- that is the safer method then getting the keyfob out of range and making sure the car is completely shut down. Not sure why that wasn't my first though but its the end of the day so that's the excuse I'm running with. =)

I'm thinking of the cooling lines that were directly connected to the DMEs in the F10. Had to be capped before shipping to make sure any residual water wouldn't come out in transit. There's no water in the F90 DMEs to worry about?

The cooling lines on the DME are still present I believe, however, they are not hooked up.

[m5_mbb7]

Do any of these tunes support full E85? Would the 104oct one be the right one if running straight E?

I forgot all about those lines. No the F90 doesn't have the same obstacles there.

104 and E85 calibrations are notably different so I wouldn't recommend running E85 on the 104 file. E85 needs a lot more fuel dumped into the system compared to race gas for one. That said, an E85 file is technically made and one of the main reasons this release is so late to market -- really wanted to include it in this release for even bigger numbers. We have been battling emissions on the E85 calibration for probably the last 6 months trying to get it to pass the EPA tampering policy (formerly Memo1A) but have been unsuccessful just by the nature of how E85 burns and what the test procedure focuses on. While with some vehicles we are successful the majority of others we are not. Now working with CARB/SEMA on hopefully finding some middle ground or process that enables us to legally release these files but who knows if/when that will occur.

On behalf of all us LCI owners, I have to ask, is there a target release date for this very tempting tune for 2021+ owners?

Until encryption on the 21+ DME's is cracked/bypassed I couldn't even begin to give an approximate timetable. Breakthrough could happen tomorrow or it could happen weeks/months from now.

[Used2be]

I’m fortunate to live in a state with 93 octane available everywhere, but if I chose to buy your Dinan + tune, it would still only come in the 91 octane version with a 753/787 rating? And I would pay $1,100 more for it than the Stage 1 for 93 octane at $800 with a 783/822 rating?

But you don’t offer the warranty for a tune with more horsepower/torque than 753/787. Are the other tunes unsafe?

The warrantied file (Dinan+) is limited to the 91 octane calibration. You can run 93 on it and you will gain some slight benefit as the ECU will naturally adapt a bit of timing to compensate but it would not be fully optimized for 93 like the full 93 file. The other octane callibrations are equally as safe --- when they are run as intended. We don't offer warranty on the other calibrations simply because we can't be certain folks will actually run the files within the proper parameters (actually run 104 octane on the 104 file as opposed to 91 as an example) and thus we could be liable for a warranty claim through no fault of our own.

[Eljeffrey13]

Is it still going to have the factory LC since its up a big amount in power? And will it be safe to launch if so? And have u guys done any 0-60 times or 1/4 when testing?

[FSHNGRY]

impatiently waiting... for an LCI breakthru.. and this software compatibility solely for warranty purposes

[m4h2o]

Pardon my ignorance but DME's stage 2 tune is 143 hp increase. Im assuming that is not at the wheel? So if Dinan is roughly 120whp is what does that equate too at the flywheel?

[neoprufrok]

Can't wait for the Dinan+. Question - with a Dinan Intake and Inlet setup - will hp/tq be any higher than above? Also assume Dinan+ removes limiter.

[Eljeffrey13]

I love the wheel numbers but how safe is the tq numbers since i have seen very few tuners get to that wheel torque number on custom tunes?

[pbonsalb]

Probably not apples to apples due to different dyno types. Dinan is known to be conservative, as are most other off the shelf tunes. I doubt Dinan is actually making more torque with its off the shelf tuning than anyone else. Run them all on the same dyno and then you can compare.

Yes i understand that but using there baseline its on par with what the car has dynoed stock on a bunch of different dyno's and the gains dinan is claiming is over 120whp and close to 190wtq… which on the same dyno is still alot of gains not so much in the hp but in the tq… listen i will be happy to buy this tune if numbers are legit and safe so i just want alittle more clarity on how safe the tq numbers are and if its really that high of a number
