    • VF-Engineering claims up to 100 wheel horsepower F80 M3 & F82 M4 S55 Stage I and II ECU flash tune gains plus DCT TCU software

      Some big claims here from VF-Engineering who is known in BMW circles primarily for their supercharger kits. Those who know VF-Engineering's history know software tuning was the main weakness of their kits especially in the S54 days. Have things changed with their S55 engine tuning software for the F80 M3 and F82 M4 models?

      Maybe. They are making some big claims. They say they offer Stage I and Stage II flash tuning software. Additionally, they say they have TCU (transmission control unit) software for the DCT transmission:




      The TCU software seems to be much like the software for E9X M3's where they simply up the line pressure in the transmission to increase clamping force. This certainly is useful when torque is increased.

      So what are the power and torque gains? Let's take a look:

      Vehicle: 2016 BMW M4 (DCT) - Austin Yellow
      Software Level: HEX Tuning Stage ONE (username:1FastS4)
      Additional Mods: Completely Stock


      Vehicle: 2016 BMW M4 (DCT) - Yas Marina Blue
      Software Level: HEX Tuning Stage TWO (username:yellowssm)
      Additional Mods: VRSF Downpipes / Factory Rear Section / Berger "Cold-air" Intake


      Vehicle: 2015 BMW M3 (DCT)
      Software Level: HEX Tuning Stage TWO & Stage TWO+
      Additional Mods: Evolution Racewerks Downpipes / Akrapovic Exhaust / Eventuri Carbon Intake / ERW Chargepipes




      They get up to 497 wheel horsepower and 550 lb-ft of torque at the wheels with their Stage 2 S55 flash along with downpipes, an exhaust, and intake. That is certainly the right range and they are not claiming any exaggerated numbers or posting any glory pulls. It looks like they have a few customers running their tune.

      The problem? It's a bench flash. That means this is basically relegated to the Southern California market and VF plans to go on a flashing tour so to speak to reach other people. Will they do that before people in other areas find a local solution though? You can of course mail in your ECU but most owners are uncomfortable with doing that.

      Also, who is the source here? VF-Engineering is likely buying this from someone and the question is from whom? Many tuners do this but it's good to know the source to know the quality. If we knew the source though why even bother going to VF? You see the problem.

      Is the option worth exploring? Sure, why not? However, once OBD-II flashing gets here the bench flashes will be a thing of the past. It's just a matter of time.

        VF-Engineering has never been much of an ECU tuner. They've assembled some supercharger kits in the past and the issue was always their tuning.

        Is their S55 flash any good? I don't know but I assume they are sourcing it from someone a bunch of people already are. It probably works well but I haven't seen any custom dyno tuning from them or really much of anything on their flashes.

        Honestly, I can't even find a graph.

        Tried to post the graph, but I guess I need more rep points...

        Stock on 91 octane vs. VF Stage 2, downpipes, and BMS intake on 91 octane:

        You have enough rep, it worked.

        I mean those look like solid 91 octane figures.

        I am more interested in the burble/gts backfire features which I know is sad....VF definitely has some good rep behind them for Superchargers...I just hate how you have to crack/take out your ECU from the car in order to do the flash. Isn't this instant warranty void?

        Meh it's what you want. There are several tuners offering this.

        If the warranty is what you're worried about don't touch anything on the car.

        Whats the scoop on the VF Engineering flash? Seems to be the latest rage but it's the first one which looks promising. As nice as the added power is, I'm no longer interested in mixing fuel every fill-up and the few "Stage 2" dynos on 91 octane so far look good. What's the underlying difference with this one versus others? Which other re-sellers are providing the same flash with a different name, and which ones are different all together?

        Thanks
        Looks like they are starting to push this hard:

        Any others you can point my way? I have heard some others like Gintani/DME Tuning but theres sound not as OEM-like such as VF. Also they still require removal of the ECU if I am not mistaken?

        Look, at least with JB4 I can easily turn on/off and make it seem like nothing was ever installed. Removing the ECU leaves traces of sorts if I take it to dealer no? I can't remove that myself as easily type thing.

        Fuel-it will be releasing their S55 PI kit very soon along with a LPFP upgrade so running straight E85 isn't to far away.

        I just said above...I don't like how the DME Tuning/Gintani versions sound. They sound almost fake/non-OEM like.

        That is true.
        I am in SoCal. But still, Enzo performance requires the removal of DME correct? I would rather just go to VF in the end since they are so local.

        Look, since it is close to me in SoCal I cannot complain about that but I can see how that is a problem for others. Bench flash blows for anyone who has to send their ECU in shipping and waiting for it car-less.

        That is an interesting point of VF buying it from someone. VF definitely has the NAME to sell it so that is why it is trustworthy in a sense I am sure for even the original creator. They are the only ones really doing it this intense right now. DME/Gintani really don't have the pull I feel that VF does which is why it is getting so much heat right now.

        Like you said once OBD II Flashing gets here this will all be pointless talk, the question is...when is it coming?! Click here to enlarge

        I understand. That is why I asked where you were from. Location is a big deal. You can just go by VF and get this done and not have to worry about any downtime or not being able to contact your tuner in person should something arise. I get it.

        I mean I could tell you some VF horror stories but I can tell you some Gintani horror stories too.

        Tuning ability honestly changes platform to platform. VF seems to have a solid S55 source and they are keeping it to themselves which is smart.

        Looks like the best S55 tune out there!

        But I would like to see the Dyno Graph also showing the power under the curve not just the peak number..

        Anyhow doesn't all those curve look really smooth ?
        Even stock on 91 octane hmmmm
