I'm liking this. Would almost be like having port injection in addition to DI, might clean up those intake valves... All controlled by JB4?
Thanks for the info, @Terry@BMS !

Yes of course. And for those running E85 the Fuel-IT flex fuel kit attaches so fuel volume is metered automatically.

Is the enough LPfp volume to support the additional injector without affecting the DI supply? Do you need the BMS port injection controller with this? Souls meth be removed or used in conjunction?Yes of course. And for those running E85 the Fuel-IT flex fuel kit attaches so fuel volume is metered automatically.
Low pressure so far no issues, even running straight E85. But E50 right now is as much as we suggest due to other tuning considerations.
The JB4 uses the FSB for the CPI controller. The same JB4 control module we use to control our WMI kits.

Does that mean you eventually plan to work towards E85 as not "not recommended" status?
Also, what do I need to run E50? jb4 + what? Can it be done without an extra tank the trunk?

Sorry for the confusing question. I'm trying to understand my (JB4-based) options for using E85 or E50 or Exx, and what the trade-offs are. For me as an end-user, straight E85 (whatever happens to come out of the pump) would be most convenient / easiest (there's an E85 pump around the corner), especially if the wife is driving the car, with the ability to handle non-E85 fuel in a pinch without changing maps. Not likely to happen, but I'd rather be safe than sorry.. So one question was - are you hoping to eventually be fully flex-fuel? I understand it might take a while to get a better back-end flash, may need a new pump at some point, etc. Or are you basically stopping development in this area at E50?
For ~E30, I believe I can just use jb4 map3? And it will go into limp mode for regular gas, if necessary, until I can switch back to map1/2? Any danger involved there?
For ~E50 we need the CPI kit? Which hasn't been released yet? Or has it? Does that require a separate tank? Or can it be spliced off the main fuel lines, just an extra injector or two? How does it handle significant variations from E50?
I think my biggest confusion is: how does he CPI kit compare to the WMI kit with E85 in the tank? Are they more or less the same thing? Or two different ways of accomplishing a similar thing? How are they different?
I'm coming from Subaru where E85 was "bigger pump, bigger injectors, tune" for many models, and if supported, flex-fuel sensor + better tune for flex fuel. I understand that system enough to know what the tradeoffs are. I'm new to the jb4 world, so trying to learn all the variations.

E30-E40 on map3 JB4 only is fine... It's higher boost levels like map7 and the stronger mixtures needed to hit them without timing drops like E50 that over burden the factory high pressure pump. CPI or WMI is required for those levels. CPI kit not released yet but coming soon.
This may be early to ask this but are these CPI kits easy to install and remove for dealer visits?

What about people who do not have access to E85, is this still beneficial?
No, on non-E85 fuels the fuel system is not a limiting factor.
Like a WMI kit, maybe easier as everything is in the engine bay, but the chargepipe has to be drilled for a 1/8" NPT nozzle. We'll be placing the required port on our intercooler kits as well.
Awesome. Any possibility of you guys making another nozzle like the WMI kits that went in before that sensor?
No not for CPI, it requires a direct 1/8" NPT bung welded to the CP.

What would be the limiting factor? Turbos?

Octane with non-E85 pump fuels. If you use unleaded race gas, the high pressure pump is able to keep up with the factory turbo limits.

Ok, so people with OEM turbos and no access to E85, WMI is still the best solution, right?
Correct

So for upgraded turbos, CPI will the recommended fueling solution? No additional lpfp needed for running even the 950cc injector?
