Typically the WMI Kit for the VR30 comes with BM5 nozzles. The reason I was asking is your AFR numbers are a bit rich and perhaps a smaller nozzle might lean those numbers out - assuming the Fuel Wires installed and enabled is not getting AFR's in the mid 11's.

Your 91 fuel will be a long term limiter but the addition of WMI should help out on multiple levels to keep your timing up.

I noticed in the product description of the for the kit on burgertuning.com, it states that WMI "...will automatically disengage during traction control...". Does this mean that the entire JB4 boost controller, fuel wires, and EWGs also disengage during traction control? Is there a way to turn this function off, so that you can run with traction control on an not worry if you get a bit of tire slip that everything will shut down?

Terry would have the definitive answer but I believe that BMS WMI statement is for the BMW platform and not the Infiniti.

Thanks, jrobohm. Terry responded to a log I posted in the EWG thread today and I asked him about this as well. I'm contemplating WMI vs exhaust upgrade (or both, eeek!).

WMI is a very nice effective octane cushion when running high timing and/or boost. As I live in typically hot weather - the added cooling effect is a big bonus. Yes it isn’t cheap, or convenient to install; but even with my EcuTek tune I still have my JB4/WMI kit installed!

hi i just read every post for the last 4 hours.... pages 19-21 when yal are saying map 7 is the meth map im really confused when this changed because previous post say it is map 8... i also just posted a complete overview/My notes of this thread below... can some one give me some specific WGDC set ups and data. ive been using jb4 for about 2 years and my horse power numbers differ significally from yals but now im worried its turned up way too high and un safe.... oh and my i just redownloaded my JB4 today and for some reason it wont log even when its saying its logging.




jb4 tuning and methanol info found via forums

On initial install, to use Map7, you need to set
Boost Additive (do 30 or 40 for starters),
Signal Scaling to 60, Min Flow Boost (12 for
starters). These settings are under Advanced>JB4
Tuning>WMI. Log and see what needs to be
adjusted.



Map5 and map7 have a leaner AFR target of
a pt or so yes. The car feels significantly
stronger on map 6 at the same boost level as map
7, because of the richer AFR.


I'd try more WGDC by raising up FF maybe to 65.



You can leave meth trigger mode = 4, JB4 on map0,
if you want no tuning or safety and just want
meth to flow.

To have WMI add 1-2psi you'd enter what you want
added under map6 and then run map6. There is a
safety option not in the current firmware we'll
need to enable for you to accomidate it meth
safety mode = 4. Email for that if you need it.


Remember to look at the notes for V8, the
maps changed function. WMI map is different
now. I kept it the same and managed to turn
on valet mode haha.




orange wire to pin #3
Blue to pin #16


ethanol setup = all off


map 8 is 0-10psi above stock this map is methanol
specific and uses the canbus systm to give as much
boost as possible depending on the flow of the
meth also while keeping the engine "safe"


A 75 additive is roughly equal to map7 while
a 0 additive is roughly equal to map1.
And it blends linearly between them



last safty =
1 boost over safty
2 afr lean
3 fuel pres. low
4 meth flow low
5 fuel trim variance

.


Map 6 is custom mappin



Set Boost Additive to 40. Signal Scaling to 60.
Min Flow Boost 10

Signal scaling is normally 60 for an FSB
running a BMS WMI pump.
Signal scaling is normally 60 for an FSB running
a BMS WMI pump. If you're using another pump it
may need to be higher or lower. It's the min
flow for the JB4 to consider the pump at full
flow.



Boost additive is how much boost you make on map8 i
under full meth flow. the higher the number
the higher the boost target. The system scales
between a map similar to map1 with a 0 additive
and similar to map7 with a 75 additive. The
additive can be set up to 100 but normally
75-80 is the practical maximum.





set meth trigger = 1 so meth flows on all maps,
1 enables WMI on all maps, 0 the default
enable WMI only on map8.


Meth trigger= 4 allows you to turn on meth with no OBDII
cable, in the event you need to datalog with an
external scanner like his EcuTek tuner did

Trigger mode 4 is meth flow all maps including
map0 without OBDII. No safety provided

it allows meth to work without OBDII data
without safety or JB4 tuning for the short term
purpose of using a non-JB4 logging tool in the
OBDII port.


Meth flows on map6 with meth trigger = 0 also.
So the best settings for most are the defaults,
meth trigger = 0 and meth safety = 0.

If you're running meth primarily for cooling
and not relying on it for octane then meth
trigger = 1 to let it flow on all maps (other
than 0) is a good bet.



"external trigger enable" from the WMI menu =1
meth trigger mode from the user adjust menu =1



Purge only works on map8 seems like.
doesn’t work.*** FYI - Purge only works on Map 7
apparently this changed along the way possibly
not sure on how accurate this is.



Fuel wires are responsible for the leaner
target AFR that you see in the log. WMI is
responsible for needing less fuel trims added
to achieve the leaner target AFR.




high boost over 5000 (17/18 psi) you're
just pumping heat at that point.






Added support for JB4 fuel control wires.
To enable install wires to JB4 and set
FutureUseD bit0 on. Once enabled you'll
see "fuel enrichment" dynamically adjust
in JB4 logs as it drives AFR up to the
revised targets. Setting bit0 on WITHOUT the
fuel wire will not negatively effect anything,
but AFR readings in logs will not be accurate.

I wonder if using the 375ml nozzles from
Prometh would eliminate the leakage? I’ve
been consider because of their superior
atomization...better than Snow’s. Their link:
https://prometh.com/collections/nozzles

Ok Folks, I installed the ProMeth 5 GPH
Nozzles (w/filters) and the Atomization
is AMAZING! They are an excellent pairing
with the BMS WMI Kit...perfect fitment into
BMS inlets. I am considering a bump up to 6 or
7 GPH. Here’s the link to #5
https://prometh.com/products/5-0-gph...jection-nozzle




reduce plug gap to stop quenching of methanol
seems to me you cam run up to pm8 nozzles



Map 6 (Flat - 0 across the board) with WMI
on top of the Speciality Z Seb tune
(to account for the HPFP / LPFP adds.)
Car is a rocketship - really want to do
some fine-tuning with Seb on the dyno here
in North Texas (Jotech.)




Terry has chimed in on this earlier but placing the injection nozzles pre-turbo does make the install easier on the VR30 but may not be considered the "best" placement (see article link).

Where to locate your alcohol-water injection nozzle - DevilsOwn Injection


It's well documented that closer to the intake
manifold/combustion chamber is better for
performance. When you spray upstream of the
turbo, it will vaporize sooner, which means it
can't pull anymore heat out. By spraying closer
to the intake manifold, you are letting the A2W
intercoolers do their job FIRST, THEN the
meth/water can pull heat from the already cooled
air and pull heat out of the combustion chamber
allowing more boost or timing by raising the
knock threshold. It is giving you a better bang
for the buck so to speak. That said, it is true
that the install can be more involved as you
have to unbolt and move around the A2W coolers,
but you don't disconnect the water lines so it's
not bad.


^^^^ my take on this answer is the intercooler would be doing its job either way and equally efficient. cold air can get cooler and hot to cool to colder is also the same effect. its late i hope that mad any since and ive been reading for 4 hours lmao my head hurts.

That's a big post - lots of history in these forums - some of which I have forgotten. Starting with the basics - please update your signature to include your car's details (year, trim line, drivetrain, modification list, etc. - take a look at how others have listed theirs as a guide.)

It would also be helpful to list for us your current JB4 settings. This way everyone can look at what your setup/configuration looks like so we can comment.

Lastly (yes - after we iron out your logging issue) - please upload a couple of 3-4 gear log pulls so we can see what your car is doing with the fuel, WMI, boost request, etc.

A log with default settings is always a good first step.
