My Meth Injection Setup - Please help

[epiphanyray]

Ok, right off the bat, I dont know much about this and had a team of guys who install JB4 and other BMS Methanol Injection Kits install this for me. I will try to give you guys background details in order to possibly rectify this issue.

But before that, here is a little background. My car is completely stock except for a Mission Performance Flash (22 lbs of boost). I had Alex setup Data Logging on my car, and ran more than 5-8 pulls in third gear from 1500-7000 RPM WITHOUT METH. Car ran flawlessly. According to his calculations and data logs, im at 640 ish WHP. NO METH, NO PROBLEMS WHATSOEVER.

I live in the Dominican Republic, and all turbo cars have a major issue with HEAT SOAK. So I installed the components listed in the image below.

It is NOT a progressive system and boost is simply coming on at 15-16lbs of boost. I have a nipple installed in the charge pipe measuring BOOST (ANALOG). (Yes I know its not a digital read out, and its not the BEST way to get boost signal). It is an on/OFF system. I have calibrated Meth Injection Controller by screwing the hex screw clockwise until it got up to 16lbs of boost. Then meth comes on.

THE PROBLEM:
every time i do a pull at WOT with METH ON, I get engine misfire code. it varies from misfire on cylinder 4, or 8, or 5. Its different everytime. ALEX says meth may be coming in to FAST, which is why I delayed it until boost hits 16lbs as opposed to the DEFAULT CONTROLLER Setting of 10 lbs. All spark plugs are BRAND NEW replaced about 3 weeks ago, and gapped to .019. Do you guys think this may be the issue? Too much spray to early? Should I get a progresive controller and have less spray at lower boost and more spray at 20+ psi of boost? A little guidance here please.

By the way, Meth setup is definitely cooling everything inside. From a stand still and having IATs at 140 degress F, If I slowly give the car gas, and allow meth to spray, temperatures go down to 116-120 F. 20-25 degrees cooler which is nice.

Possible culprits?

1) meth is coming in to early since car shoots to 18-20+ lbs of boost at very low RPM, thus causing flooding?
2) Nozzles to big? CM10 is what is on, and what everyone recommends.
3) My mixture is 50/50 meth/distilled water, should I try water only?


Check images below, to see components, and one of the chargepipes with Boost Signal Nipple. Also see quick walkaround video here:

Thank you ALL!

Subscribing. I hope you get the meth issue fixed

Thanks me too. I really have this strange feeling that I am simply spraying to much too fast. I am under the impression that a system that sprays less would work. Our cars seem to jump to 16+psi of boost in first/second gear in 2-3 seconds. So too much spray at such low speeds/rpm would cause this.

This is why I am hoping other experts could chime in. Maybe I should go down to CM7 nozzles.

Give pure 100% distilled water a try and see if you still get the same errors.

Other things you can try is to switch to Map 1 or Map 2 and see if you still get the same errors. If you do then you will know it is not related to the Meth/Water Injection system.

Thank you for such a quick response. I dont have JB4 installed. My ECUS are flashed, so I have no option to switch between Maps. Without meth, the car runs fine. When spraying meth is when I get the misfires.

You might want to take the nozzles out the charge pipe and make a video of how the meth is spraying. Sometimes the cm10 nozzles aren't closed all the way and it sprays way more meth than what's needed. The meth spray should be in a fine mist. Post a video of how the nozzles are spaying. You can adjust the nozzles spay pattern with a small flathead screwdriver if they aren't already adjusted.

I hate to bring it up, but I need to since this is my next mod. How high of a risk is hydrolocking due to flooding the engine with meth/water?

I will have to try that. Thanks for the suggestion. That is still in line with my theory of spraying to much meth.

Any other theories?

I heard this is only possible with a considerable amount of water. Unless it keeps dripping into the intake.

I had this exact same problem, my meth comes in at 15 psi which is the ideal set-up, but i was spraying way too much too fluid, and it used to keep misfiring and cutting out, until i reduced the injector size.

Your set up is perfect other than your injectors are way too big, CM10 are massive for only 22psi on stock turbos, try half that size and you'll be fine !!

I used 50/50 - but pure meth makes more power for me, if you use only pure water it will be best for cooling but wont make as much power, but your choice

Glad to find a fellow board member with the same issue. I have a friend willing to switch out to CM7 nozzles. I will have to try that. What kind of error were you getting? Does the engine just go into limp mode and give you a Drive Train Malfunction?

Maybe BMS recommends CM10 nozzles if you run a REALLY agressive map with over 22lbs of boost.

Yes drive train malfunction and running lumpy, turn off then on and it clears.. CM7 may solve the misfire, but if you tried CM5 it may have made more power, getting the correct amount of fluid sprayed is very important, i run 21 psi, and i use the AEM medium size jet if that's anything to go by, when i used the large jet everything went to shit.

Yes BMS kit is not one size fits all, i tried to dial up and down the meth spray using different pump pressure to see what worked the best, but is not good to run the car like that as it needs full pump pressure to atomize correctly, it was just a gauge for me to tell what worked and what did'nt.

Getting my meth working correctly took 2 months of trial and error, hope but your nearly there my friend. Dont forget to do big long 3rd gear pulls, i never saw the power until 2-3 hours of ECU learning just FYI

Amazing... THANK YOU! you are describing exactly what I am experiencing. I get the error, and then shut off car, and back on error GONE. CM5 may be the way to go.

When in traffic, in this weather, my IAT shoots up to 139-142 degrees F. Will I be able to signficantly bring down temps with a CM5? Hopefully to around 120-125 F?

Don't think your temps will suffer much by using the correct injectors, good luck mate

[RPiM5]

Didn't see the injector size before. Yes try a smaller injector size and see how that works. I'm using a CM5 on for my Meth Injection I believe. I've never had problems with my setup. I've also made power with pure distilled water too, just not as much as 50/50 mix. I do believe that the Water Injection system in the M4 GTS makes 50 more horsepower with just water as well.

Will do. what kind of temp drops did you see with Cm5?

[apexlocator]

Hope you get your setup dialed in OP. I've been sorta logging IATs, and yes at idle it'll go up to 140s deg F. But just driving the car will bring temps back into the high 120s. I expected a water/meth setup would lower IAT to sub 120F....

Anyone with water/meth setup log their IATs? I'm sill on the fence about setting up water injection....

[wheelpro]

I think your problem meth control how it work
You use met control start by vacum line in cp !!

[Mike@N54Tuning.com]

BMS also has PWM control enabled on the JB4 FSB, I do not know if they added it to the M5 firmware but can't hurt to ask them. Then you can dial in the meth flow % using the "fuel enrichment" values by RPM.

I just installed the snow performance stage 3 kit. And it's super easy to tune so far lol. This post has a lot of info on it. http://www.e90post.com/forums/showthread.php?t=297336

I did! Smaller nozzles did the trick. No more missfires. Running cm5. Might try cm7 and see what happens.
