NEW RELEASE: Dinan N63TU3 Performance Engine Software (20MY ONLY)
Part Number(s): D900-N63-T3-TC-S1 & D900-N63-T3-TC-S1-W Applications:
Product Page(s) / Pricing:Release Date: Available Now! Description: Even though a step below the S63TU4 and the immense power that that M engine wields, the N63TU3 still shares much of the same V8 architecture and is plenty capable of feats most powerplants can only imagine. Paired with a Dinan Stage 1 calibration yielding max gains on pump gas of nearly +110 WHP and +140 lb-ft of torque, the N63TU3 and the M550i/M850i it powers, instantly evens the playing field and puts the platforms on level footing with the alphas of the brand. The imposing gains are eye-opening on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive achievement. Utilize E85 and the gains jump yet another factor of fun -- a mind boggling additional +207 WHP and +205 lb-ft of torque to be exact. Even if you wish to retain the 4yr/50k warranty, maximum gains are far from paltry with the Dinan+ variant registering gains of 81 WHP and 123 lb-ft of torque. No matter if you opt for the peace of mind or pursue the greatest power potential, you will enjoy the results and the childlike grin it puts on your face. 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.

Thank you for the release and all of the detailed performance data! I'm delighted to see the interest in the N63TU3 engine. Do you plan to provide a platform to allow those of us with unlocked DMEs to flash the software ourselves?

We continue to investigate external solutions as well as work on our own in house reverse engineering effort for the newest encryption. Remains to be seen exactly how either path will come to fruition but we are trying to take into consideration what is out there already so that there is maximum versatility and less need for additional expenditure in reflashes/unlocks/etc.

question
How does this compare to the JB4 Map 2? I had 3.16 0-60 and 11.18 1/4 mile with JB4. Wondering if the tune feels better in the mid-range normal driving experience? Also can our cars run on E85 without changing any physical hardware, ie. - fuel pump etc.?

And yes, the N63TU3 can handle E85 with software modifications only and no changes to hardware (fueling system or otherwise). The E85 callibration is using our local E85 (MAPCO) straight from the pump (so E60-E85 but this particular station tends to be E75 and above). |

how does your wheel torque only go down by 29 pounds from the measured at crank value (717 at crank versus 688 at wheels)? That is only a 4% loss, I'm not even sure that is possible. It seems there is an error in the numbers!

The figures seem reasonable overall and it's good to see the torque is managed to around 700lb-ft to prevent bendy rods. I was going to say the dragy numbers aren't great, but the DA is pretty bad so these are definitly worst case. I'd expect the stock and 93 numbers to be 0.5 seconds better with a good DA. Personally I've done 11.6@120 stock and 11.45@122 with xHP, but on a prepped strip, as it's too dangerous to my licenses to do it on the street (criminal offence) Not so sure about the E85 number though. And super interesting re: E85 given a lot of internet wisdom says E50 is the max. A hell of a lot easier to just run a tank of E85 instead of trying to work it all out. It would be a lot safer with a flex fuel kit (come on BM3). |

HP = TRQ * RPM / 5252 TRQ = HP * 5252 / RPM If you don't trust the crank numbers or the formulas feel free to only look at the wheel numbers as those are directly averaged of 5 runs on the chassis dyno. The crank numbers are really just there so it can be compared to factory ratings as some folks desire. As far as the crank numbers go a couple notes to make it clearer how those numbers are derived:
To get the numbers in your specific example---
Are there flaws here? Sure -- but again, its more of a reference for gains and a comparison to factory ratings so as long as the methodology is consistent it should be relatively accurate, or as some would say in the building -- "directionally accurate".

Ok now I get it, your explanation is great. I was focused on the delta between the wheel and crank torque but the crank numbers are only factored so they are not material. I find it very interesting the difference between the tuning approaches between Carbahn and Dinan. Carbahn increased their torque by only 9% and you have increased your torque by 26%. That is a massive difference Dinan wheel torque at 688 lbs and Carbahn at 583 lbs. It seems the Carbahn tune is much more conservative. By the way, to get your tune done I was quoted $1,565 by one of your authorized dealers. $700 for the tune and $860 to pull the ecu and mail it both ways. Thought I'd tell you so you'll understand why folks are asking to have another way to flash rather than pulling the ECU. The tune price of $700 is very reasonable, but I'm not going to pay almost $900 to have someone pull the ECU and mail it....Crazy. And no I don't feel comfortable pulling it out myself....

Tis my understanding that remote start was not an option with the 20MY. Neither of our development cars had the option though so nothing has been tested specifically on the M550i. That said, if the option does exist it more then likely can be retained using the same process/patch for keeping remote start we utilize on other G chassis vehicle flashes. |

Are you using the BM3? Which tune are you running? Do you still like it? |

Here's an interesting chart that I put together based on all the data published by their websites. I understand this is not an exact science which is why I am only looking at the % increases of HP & torque only. When you line it up this way you can see why all of these tunes are netting similar draggy results...It also helped me understand why my 0-60 and quarter mile are so fast with JB4 in relationship to some of the other tunes. Regardless, it does look like you get the best of both worlds with the Dinan Tune.

I also overlayed the Dinan chart over the JB4 chart with them aligned at the baseline torque values. They look really close up until 4k rpm and then Dinan maintains for much longer. Not sure how different the JB4 would look with 93 vs 91
octane. |
