With as long as the JB4 has been around, revisions, etc etc I'd have thought that this would be standard. It'd suck to have such a small tank, but I can see now why some opt to use the factory washer fluid reservoir since it's got a level warning sensor. The biggest reason it popped into my head is because I was looking at a tank that's $70 less than the biggest tank that BMS offers and has over 2x the capacity at 5 gal tank, which includes a level sensor.

So i just got a met kit from bms. Currently running a custom flash on map 4 . How do i control meth flow while retaining the flash tune??

You could post a log of what you have in the support area and based on that we could offer advice.

Hi Terry, no i mean I don't understand how the jb4 should be set so that I get meth control while using a flash. I've had to set the jb4 in menu 4 to follow flash target boost and run in map4. This as I know ignores most of the tuning from the jb4 and allows wastegate control only, so does that mean it will not be able to control meth?? I always thought map 3 was for meth control but will that not then ignore my flash tune? I'm confused and can't find solid information. This is all new to me

I am probably the LAST PERSON to be offering any advice around here, BUT

It sounds like you might be confusing Map 0/3 the meth driving map, with map 4/2 the backend flash setting "map".

I have meth and BEF, using 4/2 to use BEF and drive with 0/3 for meth flow while driving.

Not sure if that's the case but it sounded like it. This stuff is VERY confusing until you start recognizing the terms used and so-on. Good luck.

Don't ask BMS about meth and PI, you'll be waiting awhile for an answer.

BEF's are the only flash tunes that work in conjunction with the JB4.
As you are currently running a full flash with the JB4 in menu 4/4, it is disabled except for gauges and data logging. To run map 3 progressive meth, menu 0/3 you would need to be in menu 4/2 or 4/3.
Someone correct me if I'm wrong.

Hey guys, my BMS methkit is installed I'm just wondering, i'm running 96% ethanol in the methkit, does it matter? Or is it better to run meth/water? It seems the only major difference between the two is price?

Bottom line, it shouldn't really make any difference.

Meth has better cooling properties than ethanol, and water better cooling properties than methanol.

Methanol is higher octane than ethanol. The AFR on methanol is 3 to 4.5:1 vs ethanol 8.5:1 so you can burn more methanol and make more power. It wont matter much to the car as it's targeting a lambda value, aka oxygen to fuel ratio. Probably 0.8, based on what's in the back end flash.

Whether you use high concentration ethanol or methanol it doesn't make too much difference I suspect. You are providing more than enough octane.

This is despite the fact that a 70:30 water meth mix absorbs a serious amount of heat from the engine.

I'm currently using Boost Juice, aka "49%/51%" m/w ratio. My tuner thought I should go higher meth, but I declined for safety reasons.
You make it sound like maybe higher water mix is preferred?

I don't know much about this stuff...just hanging on by a thread...lol.

Lambda to me is one of the Frats in Animal House...

But I'm always willing to learn and/or hear different opinions.

Thanks!

50/50 is generally the minimal requirement. If you are octane deficient, than you up the meth content as needed. If you don't need the extra Octane/fueling, adding more is unnecessary and will just accelerate buildup in the filter, nozzle, etc.

Makes sense, thank you.

Btw, what is the "maintenance schedule" for the filter and nozzles, if there is a known formula for one? 50/50 mix on 15k/yr daily driver, activates at 8 pounds...go through about 8 oz a week maybe(?).

8 oz a week!? How do you control yourself? lol

I'd think that filter and nozzle maintenance would vary significantly, based on how OCD the individual is that fills the tank.

I use only filtered tap water and a dedicated mixing jug.
Based on very minimal minerals (multi filter setup) I'd expect the nozzle to be clean for a year.

I'll test it after 3 months though.
I got a base line prior to installing so I will know visually when there is alteration in the spray pattern / atomization.

Also, while my tank is spotless inside, my drawing pipe sits 5mm above the bottom of the tank, so it will not be so likely to pickup any possible sediment.
I'll also wash my tank every 6-12 months to ensure it's clean.

Due to being proactive, I expect low reactive based maintenance.


P.S. Hi Radar! Thanks again for all the early guidance when I was setting up my JB4, Bluetooth, etc. Reading about your WMI setup was a motivating factor for me. I'm mounted in a different location, but your build was very fascinating.

Default Suggested BEF for meth + pump - 02-12-2020, 02:11 PM

Hello.. I have a 335i ST 6466 runing pump gas + PI meth stage 2 lpfp + fbo

I wonder which would be the best BEF for the car.
I am msd80 ST TS PI but I don't have e85. Just pump and meth. Does anybody know if I can run a e85 flash with pump + pi meth.
As all PI maps said E85 and there aren't PI + pump.

Thank you

Iím sorry I didnít see this post sooner. I donít really get useful notifications for some reason.

You are so very welcome!

Thatís really cool to hear, and makes me feel less guilty for being such a pain-in-the-a@@ with all my questions to all the N54 gurus around here! Lol

Love to see what you ended up with. PM me a phone video if you want to show it off.

Default Meth solenoid not triggering - 08-18-2020, 03:35 PM

*** Resolved, FSB Version-1 is ground triggered.. /o\ lol

Hey all, just finished BMS WMI kit installation but am not getting solenoid activation. I can purge the pump but the solenoid does not open during purging, i checked the solenoid and wiring itself and it tests fine and activates with 12v+. wondering if the fsb is bad or if i missed something? attached is the wiring diagram i made during installation and it seems to be correct from what i pulled out of the installation manual. few changes from the manual to the fsb in my older kit but all seemed logical. any thoughts or ideas I would think if the pump activates while purging that the solenoid would activate as well?

thanks in advance!

Chris

If the pump is working then take a live off that and connect to the solenoid. The other wire just needs to be ground?

Have been using map 5 and running 80/20 meth/water.
Are there any benefits to running the dedicated meth map ?
