1. JB4 integrated port injector duty cycle is based on a few things but primarily boost and RPM. It does not spray all the time, only above 2K rpms under moderate and high boost.

2. Update to the latest firmware.

3. No need to do any flashing or updates with that box.

Terry, just a couple questions about the new controller with JB4 integration

1) does the new controller work as a standalone injector controller or requires JB4?

2) if misfire cuts cylinder DI fuel is there a failsafe to cut PI fuel to that cyl so as to not create hyper lean condition that can blow an engine as it happened on my engine failure?

(Info maybe in the thread but would take too long to read 35 pages, apologize if it's been answered before)

So is there any kind of trade in program for swapping the aic for the bms module?

Well found on page 33 that my question 2 was answered. Looks like the only way jb4 cuts fuel is if it sees 20:1AFR for a period of time (1 sec?). Seems to me that is a bit high I would think its better to lower that threshold. My cylinder blew from the misfire/lean fire condition at less than 20:1 AFR. Really would be slick if it could know there was a misfire and DME turned of cylinders and PI did the same so they both failsafed in concert, that would trial one of the key safety features being tauted by the Uber expensive syvecs.

Still curious about question 1.

Answer to question 1...no, it does not work as a stand alone.

Hello BMS gents,
Would one be able to buy the JB4 port injection control and the fuel splitter hose separately? Also a price for a set of 6 injectors. I'm looking for everything except the manifold spacer/fuel rail.

Thanks
Kyle

I bought the controller separately from BMS.
Also, you can get hoses direct from Fuel-it.
That's what I did with my AD Engineering PI.
My AD Engineering PI had the injectors, but I would assume that BMS would sell them separately.

Yes, in the newest firmware the FUA options are as follows.

FUA Twin Turbo Firmware:

0-50 - Lock in a differential between DME target and ECU PSI to reduce the throttle safety. 0 = default operation. 26 units per PSI. e.g. a value of 26 would dampen throttle safety an addl psi. This value will also reduce effective load reported back to the DME by that amount. For diagnostic purposes only.

51 - Output clutch position under low fuel pressure. For troubleshooting NLS.
52 - Alternative E85 cold start / cranking fuel algorithm
54 - Output 2STEP output PID under low fuel pressure.
55 - Fueling applied as a function of actual boost rather than delta over stock target. Useful for 335is models using E85 without a back end flash map.
56 - Output road speed instead of low fuel pressure.
57 - Output 4BAR learned adaption value instead of low fuel pressure.
58 - Change DB25#2 from methanol output to E85 analyzer input.


Ethanol content will then show up under duty bias.

is the anti-lag chip needed to get the new PI working with the new BMS controller? I installed my PI today at followed the wiring instructions set on on page 33, car started up fine, with no issues, meth scaling was set to 100 and duty bias set to 50 across the range.

The car wasn't on the lastest firmware at the time, and I just updated to 32.2 hex...would the outdated firmware also cause the PI not to work?

32.2 will work but if you don't have the updated chip, it will not work.

Terry/Steve, is there a solution for this yet as I do not want to remove the fsb and meth system totally as e85 availability is highly limited here, this was I can turn the meth system on via fsb when running pump fuel to keep iat suppression in check and the performance consistent as well.

Then I would recommend using the Split Second controller at this time.

I just bought a BMS PI kit and was wondering if I could get away with just a stage 2 LPFP upgrade if I'm only looking to make 500-550 awhp max with pure stage 2 turbos. The car will mostly be on either straight 93 octane or e85 as I'm not looking to deal with mixing. Thanks!

start with low boost (20 or less) and see how your lpfp and hpfp are doing. Then you could just increase boost until your hpfp dips below 9. 10+ would be better but you could push it a little harder if need be.

Yes, you can run the stage 2 with PI. You shouldn't need to go to Stage 3 until about 550whp.

See the first page of this thread.

Are you doing JB4 integration? (highly suggested)

For connecting to the AIC, that too is demonstrated in a video on the first page of this thread.

I got a single turbo coming but will only be push about 600rwhp approx.With a E50 mix with 100% meth(Cm10 &CM05) will this be ok.I do have a Fuel iT stage 2 intank.Eventually i wll do Pi injection.

You'll have to see how the logs look...you may need to go to dual CM10's or ???

With fuelit stage 1 running E50 + 100% Meth (CM10/CM7), I made 680rw so if you want 600rw then you should be fine. Once you're up and running, log and go from there.

Just curios guys, I'm wiring in my AIC1 EV6 today and I DO HAVE the latest firmware on my jb4. I'm confused as to if I only connect the green wire to pin #9 in the USB cable and leave all other wires unhooked AKA (yellow, black, red)

It doesn't make sense to me though to leave the red and black wire unhooked because the controller wouldn't have power. And then is it ok to leave the yellow wire unhooked (tachometer) because the green wire is connected to the jb4? Or do I still have to have a tachometer reference? Any help would be appreciated! I already read through the beginning of this post and all it states it to hook up the green wire, nothing about the other 3 so I would just like to clerify. Thanks!

All wires would have to be installed... But if doing a new install with the JB4 best to just sell that and get our JB4 port injection controller so it has bi-directional control.
