So is the ultimate goal to never have to flash again due to different E mixtures and the DME to auto adjust and JB4 to read ethanol content?

Sounds on par with what it should be. Although, I would assume JB4 would be making the corrections for the E content.

Still confused how it would manipulate a flash to achieve the desired goal 🤔

I'm unsure how much in depth control JB4 has over AFR and timing when it's run on a BEF. Maybe Terry can chime in on this and give us better explanation as to how this will actually function.

Correct. JB4 reads ethanol via sensor or virtual sensor and handles everything with its logic and the improved bef maps being developed.

So I guess we would still need to flash to E85, pump, or race regardless with this feature but jb4 would automatically raise or lower timing/boost target, etc.. Based off of E content? I'd love to try the new update but I just lost compression on cyl 4&5 only at 70k miles.

Don't want to deviate from topic but not sure, could be a head gasket, valves or piston ring. I have theories how it caused one of the above to occur, but I won't tear into it until next month. If it's bottom end issue, I'm just going to build it.

Great to hear!! There's a handful of its S63 owners who are basically at the limits of what tunes/stacking allows for our engine. I know a few people who are waiting to buy their JB4 because they think this is a hardware change, but this is only a firmware update, yes?

This thread is N54 specific, but we will be rolling most changes out to other platforms as we can. What the S63 needs is good at home flashing to tweak a back end flash. It's an MSD85 DME so should be easy to do. Maybe you can talk MHD in to adding it.

My bad, sounds like Protecon (the guy who linked me to this thread), myself and the guys who are discussing this on the GroupMe app have falsely gotten our hopes up that we'd get some trickle down benefits. I know for myself that using an E30 mix caused me to max out TRIMS no matter what I do, which isn't good for daily use.

Any validity to this post then since us getting the E85 firmware update sounds unlikely? He's ready to buy but seems he's holding off due to misinformation.

As an individual asking, I doubt they'll take it on, but if it's as easy as you say, I'll ask and see what happens.

Added the BETA twin turbo N54 firmware to the first post. Email me for the single turbo version.

With this new firmware the new options on the meth page are now active. I believe Donnie added them to the android JB4 mobile interface, and they are in the windows interface, the rest are on the way.

The new field "virtual sensor offset" is used to calibrate the virtual flex fuel sensor reading. The logic still needs some work but its getting closer and more data always helps. With our E85 back end flash maps, which run a scalar of 1.30 under lower loads, a value of 132 has been working well. Which is the default value. For the factory BEF and RACE/PUMP BEF we'll have to evaluate different values. And of course there might be car to car variances.

We're working on a calibration method but one option is to run straight PUMP which should be around E10 and then adjust the field until virtual flex fuel content hovers around 10.

Hey Terry, if I have the fuel scalar at 1.40 for example, do I set the virtual sensor offset to 140 or does it not work that way and I would have to make adjustments to it to see what works?

I keep getting kicked to safety map for value 5. Anyone else? I'm currently at a half mile event.

It's a fuel trims variance fault. Enable bank2 trim logging and let's see a log.

Also, a FUA setting of 65 disables that safety setting should you determine there isn't an actual problem.

I have not made a formula yet.. So, you'll have to play with it, and find a value that works.

Can't you use Ethanol sensor and analyzer to see what your content is and adjust accordingly for the virtual sensor?

We do but most don't have a physical sensor for calibration for their specific vehicles. Looking for a wider range of user data before publishing default values for various scalars.

Could you technically add e10, e15, e20 etc... And adjust according to that data or would there be other variances? I figure it would be more accurate to utilize your physical sensor to get better readings?
