Hey so I know others have asked and Ive scrubbed thru those and havent really found an answer. I have an mhd license flashed on my 340i and a jb4 in my trunk. Should i sell the jb4 or is there any benefit to putting it on the car? I did see one release from bms showing my car make 461 WHP using this setup, however jb4 alone gave me rough, almost dangerous power.
Let me know what i should do with my jb4.

Seen the thread with the free JB4 back end flash maps? You load them via MHD. Real game changer. Gives you all the great smooth performance of flash mapping with the tuning features and mapping of the JB4.

I saw it. I didnt understand it. So basically i have a 550 jb4 +100 connect kit which is junk?

That rough feeling was because the DME was restricted it no longer exists with the back end flash. If you're going to run meth or CPI then JB4 is a perfect tool to use.

Forgive me but not sure what cpi is, ill just google it and meth is a long way out for me i understand its just for cooling yeah?
If i go into the mhd app i can crank the cooling to performance or track and the oil temp stays around 180c...i thought of getting an intercooler but decided not to because of this. The cooling system seems to be adequate. Any idea what i should do next?

You need the JB4 to run the BMS B58 backend flash maps. Once you load the free map posted using your MHD license and enter the JB4 settings so it knows you have the flash loaded then you unlock an entirely new world of performance relative to JB4 only cars. Each map on the JB4 becomes a different stronger map.

A lot of my customers due to lease or warranty or whatever don't want to flash so many continue to run JB4 only but JB4 + the flash opens up a lot more performance across the board.

So what kind of issues as far as long term reliability would i be looking at here? Any preventive maintenance i can do? I already did spark plugs post mhd.

So from what I understand from the link, is that i get to customize the mhd burbles on stage 0 and then use jb4 to select different maps?
I dont need to use my stage 2 MHD?

Any weigh in from you on this?

Running a Pure stage 1 turbo, MHD BEF + JB4 map 7, BMS meth kit, catless dp, and intake with e30 blend and 100% meth... runs like a beast and very smooth. I like this combo because I'm able to control boost with JB4 and run meth. Anytime I want to boost 24-25 psi I bump up my additive and any time I'm traveling and I can only run 91 octane I lower boost to like 18 psi and hit the road. I'm almost certain later on BMS will have updated BEF files released at no cost as time progresses.

So whats the purpose of the meth kit exactly? Just cooling?

Additional fueling, more octane, more power and cooler intake temps

When you load the JB4 flash map under options you can adjust burbles or anything you want in there. The flash map allows the JB4 to run stronger more powerful versions of each of it's existing maps.

It's an amazing combo, and I would highly recommend it. Coupled with XHP Stage 3 tune, my car is destroying people on Meth. I pulled hard to 140+ on a newer M2. He didn't even come back to play, cool guy though. I am obsessed with the sleeper appeal.

Can confirm xhp is nuts

Run the RACE BEF and Map 7 if you are on Meth. The RACE WMI BEF is weird and giving people fueling issues.

For tuning advice you'd always want to look at the logs. The RACE WMI BEF is setup more aggressively so if you're having an issue with it post that in the BEF thread also, maybe they can tweak a version down for you so it's stronger than RACE but not so strong it causes whatever your issue is.

I don't have any issues, I've just heard of other people having issues with the WMI BEF. My issue is that I want to go faster and use both Meth and Injector #7 CPI lol

We can help you with that! But, normally with CPI you don't need meth. You have E85 access?

Yes, I have E85 access

Yes I can’t wait ima use cpi too just need jb4 mhd to have a tune for it as well
