Best and Safest Meth Kit for M5 with JB4

[Orenx5m]

Any suggestion on the best/safest meth kit to install on the F10 M5 ?

Meth kit must work with the JB4.

If it must integrate with JB4 then pair it with BMS's meth kit.

^^^this. Terry will support his JB4 and his own FSB meth controller, you can for any tank and lines you want.

Go compression fittings where ever possible.

Currently the best option is using a standalone Meth injection controller with internal MAP sensor. Currently using AEM progressive meth controllers, only ~$160, but comes with even more failsafes than the JB4, and can be wired into the wastegate harness to ground the signal wire instantly killing boost if any of its failsafes are triggered, such as overboost, low tank, low flow, blocked flow, etc.

That's just not correct. The JB4 WMI kit is the only kit that integrates with CANbus allowing it to read air/fuel ratio, fuel trims, throttle position, gear, knock, etc. No other kit even has access to any of this data and as a result can't provide the same level of safety. Nor can they integrate with the tuning in such a way for progressive meth control and mapping where boost is held low UNTIL meth is fully flowing and then progressively phased in as a function of flow, meth is cut during shifts and DSC/DTC events, etc.

You guys know more about Standalone than me, answer this

Exactly - this has saved my a$$ when I was running high boost and ran out of meth on a long pull. System immediately cuts boost target to flash levels that can be supported by the standard fuel system.

If you are using meth purely for cooling or additional margin then a non-integrated system is fine. If you are trying to make real power then design the system appropriately.

Safest without JB4 is Aquamist, but it can be used with JB4 as well. The M5 has MUCH more support vs the X5M and these days a JB4 isn't even needed on an M5 considering the gains that have been made on that platform, but I'm still stuck using JB4, hence my loss and sale.

I did my research and was most comfortable with having my JB4 progressive meth control.

Thank you all.

Everyone is forgetting here how small % jb4/meth/kit whatever consist of in the Real World.

American Muscle & Other cars all using Aquamist & AEM mostly even Snow Performance has more users than JB4. Standalone kit and are about 98% of the market share vs 2% of the small BMW cars running BMS Meth tie down.

Get your head out your ass, JB4 is more hype than anything. Seen plenty of failures (more than likely with jb4 slow refresh rate since it relies on canbus not FLEXRAY). You just have all these vendors selling bms products out their ass without knowing JACK.

I've had an Aquamist kit on a 997TT (my brothers) not work period even after sending the unit over to them in the UK. Rewired the system multiple times, spent hours getting car sick in the backseat working with settings to try to get it to work. I had one in my 996TT that didn't want to play together at first with the HKS Fcon ECU, and I went to race gas all the time so I ended up ripping the system out when I built my motor.

I've messed with the Snow stuff on my buddies 03 Cobra and it worked. It was a basic system that we had to add an extra solenoid to because it wouldn't always close off the nozzle in time.

Everyone of them has flaws regardless of what one person says. Seeing as I do have a JB4 on my car I would more than likely use the BMS system and upgrade to the stainless steel fittings. Why not get one that is integrated into the product you are using on the car?

As far as CANBUS being slow, that's funny since most standalones including Motec, Syvecs, etc. still communicate over CAN when adapted to vehicles that use it. I know plenty of factory IO are controlled over CAN with my Syvecs in the Porsche and it works flawlessly and still can be monitored/logged at 20Hz.
