Bytetronik ECU Flash/Tune for the F56 JCW-Auto & Cooper-S Manual
After months of testing and tuning, we are finally ready to release our Stage 1 ECU Flash for the F56 B48. At this point, this is Bench Flash ONLY!!
We can prove consistent power gains for both the JCW and the Cooper-S models on all types of Dynos (DynoJet, Rotronics, Mustang...)
Car #1: This is the dyno gragh from the JCW (w/ Auto tranny). We ran this JCW on the Mustang Dyno in AWD mode b/c we didn't want to put the car into "dyno mode".
Modifications:
2015 Factory JCW Auto
2 gallons of E85 mixed with a full tank of 91 Octane;
Bytetronik (BT) Stage 1 Flash;
Everything else stock
Power Output to the wheels (Not BHP!): OEM Stock: 231 WHP / 248 WTQE BT Stage-1 Flash: 276 WHP / 326 WTQE (~442NM)
Gains: +45 WHP; +78 WTQE
Dyno pulls were all done on the same day within 30 minutes of one another. Outside temperature was about 80-degrees Fahrenheit.
Parameters Adjusted:
Raised Speed limiter (VMAX)
Fuel Pressure raised
Target Lambda optimized
Clutch torque optimized
Optimum torque optimized
Torque monitors optimized
Schubblurbben (burble) parameters optimized for more bangs and pop
Race start (launch control) start temperature modified
Price for the Stage 1 ECU Flash w/OBD Device: $795 + shipping (as of Dec 15, 2018, the entire flashing process can be done via the OBD2 port - there is no need to remove the ECU any longer).

I'm very interested in this for my JCW. Been used to NMs for so long, would be nice to have a true tune now. At lease I can say I've put on nearly 30K miles without a hitch! Looking on your website, I don't see anything for F56, only R53, I assume this will be updated?

We are working on perfecting other tunes for the other models. Once we get those perfected, then we will update the website with further details.

Don't see why it wouldn't; unless they changed the ECU on the B46 cars.

Running E85 in these newer BMWs is a non-issue. We see plenty of them running on 91 octane and E85 mix (as high as 50/50 without any issues). Test car was on a 2 gallon of E85 mixed in with Premium Shell Pump gas at the time of dyno testing.
Yeah I currently run 2 gal E85 with JB4. You're saying our fuel system is capable to run around 50/50? LPFP and HPFP are ok? I would be highly interested doing that. The ECU will adjust trims accordingly? Maybe I can do some logs and someone can analyze.
1) assumed that the flash will eliminate any chance of the dealer plugging in to do service work?
2) if the JB4 is a piggyback and you're a full flash, why can't you include what the JB4 is doing into your flash? not trying to shoot down the JB4, just trying to understand why someone would run a flash and then put a piggyback on it.

Because the JB4 would:
1) Allow you to change Maps on the fly. With boost control done by the JB4, you don't have to wring your car to the max when you're not racing.
2) Allow datalogging via OBD.
3) Boost limit on lower gears.
4) Meth control integration.
Fueling, timing, VANOS, clutch torque, more Schubblurbben are of course done via the flash.
hey mike...that was more my point. seems the JB4 is more of a management/quick changes tool at this point more than making actual adjustments to the system.
Yeah, but for me the ability to change map (level of performance) is pretty crucial. With the flash-only solution, you pretty much are running on a single map the whole time. Of course that is completely fine if you're not planning to experiment with higher octane and/or meth, etc.
Unless someone in the future come up with an OBD flasher, IMO JB4+Flash is the ideal solution for those of us who like to tinker with our cars.

Currently with a JB4 installed, unlike other "piggybacks", the JB4 installs between MANY different sensors. MAF, MAP, Fuel Rail, etc... So the sensor now goes to the JB4 and JB4 to computer. JB4 is the middleman. Now the JB4 is able to manipulate many sensor data to increase boost/fuel and what not with its own integrated "maps".
Now when you install an ECU tune. You run the JB4 in a "pass through" mode. All data goes right through the JB4 without manipulation (if you wish). The JB4 is now there for you to "monitor" everything. Safety systems within the JB4 are still integrated since data needs to pass through the JB4. Say your car AFR leans out, overboosts, fuel pressure low, meth flow low, the JB4 will bump you to a safety "low boost" map every time (map 4) to save your engine from damage. JB4 also has cold/hot oil protection built in. So you will have stock like boost until oil temps are over 160 degrees or for oil temps over 280 degrees.
You can still use the JB4 to hijack your gauges for map switching on the fly, or using your fuel gauge as a boost gauge (examples). The JB4 can change your throttle mapping for a linear experience. If you are having trouble putting power down, you can us the JB4 to limit boost and set a boost target for first, second, and third gear (Via in dash controls, JB4 mobile app, or JB4 application on computer). You can use the JB4 to run a meth injection system with your car (Can set up parameters to when to engage/disengage via JB4 software). Use the JB4 to read and delete trouble codes on the fly. On the BMWs, the JB4 will run the No Lift/2 step systems. You can use the JB4 to be in charge of fueling for E85 mixes or be in charge of whatever parameter you want.
The JB4 is pretty damn cool, and I am happy to have a sophisticated management system for my car that I feel is a bargain in price with all the support and features it offers. Makes me feel better, and wish I had support on my R56 for this! Especially running a bigger turbo, standalone meth injection system, and messing with E85 mixes. I would have a much better peace of mind lol.
I'm sure I missed a lot more features from the JB4 but thats the jist of it.

You are very correct on the above point

The flash can raise the limiters and built-in parameters that are hard coded inside the ECU so you don't hit 'limp-mode' while using the JB4. The JB4 has map switching and can alter the boost level, timing and other parameters "on the fly" while still keeping the fail-safe parameters within the stock ECU (i.e. knock control)
There are a lot more potential with this Flash+JB4 combo... data logging using the JB4 is sooo much fun... and you can log it on your mobile App via the JB4 Mobile App
Now when you install an ECU tune. You run the JB4 in a "pass through" mode. All data goes right through the JB4 without manipulation (if you wish).
based on this, for someone who is running the JB4 right now, it seems our steps would be to do this flash and remove the JB4 until the combo system is released which i imagine would come with a new JB4 code.

No. Map 0 will disable the JB4 completely running everything from the ECU.
And Map 4 or 5 (I forgot) will use the ECU values and the JB4 is still active for monitoring and data logging.
Then of course map 1 and 2 are the burger maps that manipulate values with factory tuning.

it's map4 that uses the ECU values while the JB4 still monitors.
but now we can't use MAP1 and MAP2 as we are no longer dealing with the factory tune. the way i ran by JB4 was as follows:
MAP2 at the track
MAP1 daily/street driving
with the bytetronik, there isn't a "map1" or "map2" anymore as it's all done via the bytetronik. so again, when i refer to "removing the JB4", i guess the better statement was "disable the JB4 to longer manipulate values and just be a tool to manage and protect the system (as well as it's cute add'l features".

same question as i asked in previous post. given that JB4 Maps 1 and 2 raise boost values based on stock/factory tune, are you saying that the Flash still allows for a +4 and +6 manipulation being added by the JB4 (ie running a Map1 or Map2).
understand that i'm just trying to understand things right now. i'm all for this and am ready to pull the trigger...just want to understand more.

Yes. We are working with BMS currently to find out the most ideal "back-end flash" that will complement the JB4 settings. We are doing a lot of data-logging and map comparisons. Once finalized and tested, then we will publish those results.
Of course, these new JB4 settings (Map 1 and 2) can be done via a firmware upgrade from BMS.

We can perform the work here at our location, but you'll need to make an advance booking. We are on the road a lot and prefer the 'remote method'..

ok, so what's next. how does someone get in contact with you to get this started..i emailed you guys yesterday although not aware if that was the right method (or email)
are of course done via the flash.
