Could you please elaborate on how this is possible from just a tune? |

Maybe Dinan really means using E85 with pump gas to make E30? Haven’t read of any tuners yet with full E85 tunes because 1/3 more fuel quantity is required. Many offer E30 tunes and some custom tunes might be E40.

This is a good assumption and if this was the case i would assume it would be explained. Honestly you are probably right because I don't see how E85 could be used with no other mods but then again If what you're saying is true is that capable of putting out those kind of numbers?

Not a calibrator so I couldnt say what exactly is being done (nor would the information likely be shared) but it is probable that this E85 calibration is using the same strategies that were employed on the B58(O1) (M340i) for the full E85 tune on that platform. That was released back last March and at the time no one else was offering a straight E85 tune to my knowledge, citing that the fuel system wasn't capable of handling it. Fast forward a year later and competitors are starting to offer full E85 tunes and no other modifications for the platform so apparently it was possible after all despite all the clamoring saying it wasn't real. Same can be said for the remote start disable on the same platform that was resolved. Just because not everyone has figured it out does not mean it is not possible. No. Still just for the 2018-2020 (06/2020 build date and prior) models. |

Is it true to run a tank of 93 after 3k miles using e85? Also the quality of e85 could be different from gas pump to gas pump. What if your not getting 85 and happen to get 80? |

The E85 tune has an operating range of E60-E85 so pump variability will be of little to no concern. |

A little tough to believe these numbers without 0-60 and 1/4 mi times...
Especially hard to believe that a company like Dinan would invest a tremendous amount of resources to develop and bring the tune to market...but can't supply the most basic real world numbers instead of a "graph" they made themselves? Sorry but at face value it's full on patently ridiculous. Real world numbers are among the very cheapest performance numbers to acquire and there is only one reason to omit them. If the real world street times backed up these claims Dinan wouldn't need a video reel to sell it. Sorry but I'm calling BS until Dinan posts actual draggy numbers. P/S @Dinan- you can use my draggy if you can't spare the $150, just message me. Maybe one of the giggling professional drivers you mention who are using launch control will post some numbers...

true some 60-130 times would be ideal

im really curious now i just gave dinan customer service a call since i wanted to acquire some knowledge! they said they personally don't do draggy numbers as it can vary to much from car to car. regardless my m5 is 2020 so my next concern is the bench unlock and how long i will have to wait for the ecu and the flash and they said they still have to unlock it and flash it themselves i was ok with going somewhere bench unlocking it and taking it to a local dealer for them to flash but he said he doesnt recomened that

I am going to try and pull my ECU's out this weekend or sometime next week at the latest to send them for the E85 tune. Once I get them back I will do some dragy runs and also take it to the track to get some slips. I am in FL so the weather isn't the greatest but at least everyone will have something to look at. I am not expecting amazing times since I already have wheel spin with my current Evolve tune.

As far as Dragy data -- we haven't really started doing the Dragy thing until this past year or so and its not something the engineers use for development purposes. More of a marketing tool than anything since those numbers can vary a fair amount car to car, run to run via temp, tires, reaction time, etc. Yes, I realize dynos can vary/be manipulated as well but given controlled conditions a chassis dyno is still the best way to generate repeatable results. As such, our focus is more on the dyno for large changes and then street tuning to work out the nuances that don't get addressed/seen on the dyno and general drivability. 0-60 and 1/4 mile times aren't ever a specific goal -- just a side effect. Drivability is always the key thing being focused on. Performance without sacrifice and all that. Engineers will often go to the tracks around here for stress testing and on occassion to a drag strip (although the latter has fallen off in recent memory). Information garnered there is simply more valuable as we can achieve sustained loads over much longer durations to see how heat can be mitigated and how systems function under more diverse conditions. Not to mention we can test suspension components. Pretty sure the stock M5 at least went to a strip but haven't been able to locate the email with the slips. Definitely never took it to the drag strip or captured Dragy data on the tuned side though. Unfortunate, but it is what it is. Our shop M5 is currently at a sister location getting some MG1 development work done and has been for a couple months now or else we would just go out and capture some Dragy data but that isn't an option at present for the veicle. The intent was to bring it to a local strip test day they are having there for some of their domestic projects and get some data at the same time. Still working on scheduling that out as far as I am aware. I intend to update the website with that information when it is available however. What we do have on site though and have some direct control over is our 2020 F95 X5MC. While its not an exact comparison to the M5 seeing as its AWD and significantly heavier it still is running the same engine with the E85 tune. Data from it this morning/early afternoon is below. Keep in mind it is officially early summer in Alabama so conditions are far from ideal for these captures. 0-60 in 3.16s 60-130 in 8.15s 1/8m in 7.08s @ 103.37 mph 1/4m in 10.88s @ 129.08 mph Not going to be able to post 93 octane (stock) numbers until Monday or Tuesday next week as the vehicle is being prepped for a local show this weekend and we are up against it already. Simply don't have enough time to deplete/pump the tank out and put 93 in to do those runs while also getting it detailed etc. Once that happens though you will be able to really see a real, and meaningful, delta between stock and tuned in like conditions. Data above on its own doesn't really tell us a bunch other then the car is fast. In the meantime the only other Dragy data I could find relatively easily online for the X5MC was from a RaceChip tuned example on 93 octane (thread is HERE). It output: 0-60s in 3.28s 60-130 not taken. 1/8m in 7.29s @ 95.77 1/4m in 11.40s @ 119.07mph All in MUCH more favorable conditions (~500DA vs ~1800-2200DA). The difference in trap speeds are telling though. Ultimately thats some marked improvement in all categories over an already tuned vehicle. Quote:

This is not about a hatred of dynos. As the dyno guy at a HD dealership for years, I personally performed thousands of dyno runs while performance tuning HDs. As an IT pro now, dynos are the perfect marriage of my favorite interests. But this isn't about dynos, or a graph that, yes, "you did make yourself". We both know a dyno can be made to say anything with the click of a mouse so don't gasp that your graphs aren't taken as gospel by everyone in the world. At the end of the day what matters is real world performance. I'm simply calling you out for not releasing real world street times while pretending that Dinan just can't be bothered to do it, or maybe did it, but the numbers were misplaced, and why does everyone hate on dynos, snotty bullshit. Who do you think your audience is here exactly? Do you think a bunch of dumbfucks are running around, buying M5s and tunes, and bothering to read the BMW forums? No one takes issue with using dynos for development so don't strawman the conversation. The point is the ridiculous claim that the most famous tuning outfit in the world can't actually time a test car. Yeah right... Everyone else manages to release times and graphs. Just not Dinan, apparently. I'm not even going to take the time to break down the other obvious bullshit like, "draggy times are for marketing". Give me a fucking break. No one is telling you to use draggy during development but stop pretending it's some stretch to release a single real street time while finding time and resources for your ridiculous sales reel.

Dragy times sells..
I'm in the restaurant business and if I want to sell a shit ton of linguine d'mare you better believe I'm posting a picture of that dish. Not going to sell it just by describing it. It may sound good but ppl need to see it and eat it up with their eyes. Your graphs show me power number which look great but I really need to see what you cooked up with those dragy numbers.. Damn now I'm hungry 🤤 |

As promised last week below are the stock (93) and Dinan Stage 1 comparison Dragy data for the shop F95 X5MC. Again, not a direct comparison to the F90 as the X5M is notably heavier ( ~5425 lbs vs. ~4370 lbs) but it is the same calibration so will give you an idea of gains/deltas.
Not to shabby for 2000+ DA here in early summer in the south. As noted in the earlier post the traps are telling. Last edited by Dinan_Engineering; 06-06-2022 at 04:19 PM.. |
