Interesting situation.

Meth stopped flowing on Map 3. Well on some random pulls it would turn on, but most of them no meth.

Map 1 on the other hand flows meth every single time. (Meth Trigger = 1).

Took these logs after lowering Min Flow Boost to 6psi. Still have issues.

Cooper S F56.

JB4. BMS Meth kit. DevilsOwn Size 7 Nozzle.

See attachments for logs.

Thank you in advance

Attach the CSV files to the post directly, not in a zip folder.

Opened one or two, don't see what your issue is. Photo of the WMI user adjustment settings?

Map 1 and 2 flow meth perfectly fine.

Map 3 (meth map) stopped flowing meth completely for some reason. Or has random spikes of meth flow on occasion.

Out of precaution, I rewired the entire system for more reliable connections. Same issues unfortunately.

Must be something on the software side.

Thoughts?

Logs and settings attached.

What about meth trigger = 0, does map3 meth work consistently then?

[johntotah94]

Negative Sir.

Meth Trigger = 0. Still does not flow Map 3.

Meth Trigger = 1. Flows properly on Map 1 and 2. Not 3.

I would suspect some bugs in the MINI software. Also, when I let off throttle, AFR goes to 3.8 all the time. Don't think this is correct either.

Log attached.

Thoughts? Thank you

AFR is correct when letting off gas as fuel is cut off. It's only valid under normal load levels.

Found a bug in the firmware. Try this.

Seems to be working fine now. Had 1 time where it didn't flow. Changed Min Flow PSI from 7 to 6. So far so good.

Trying to figure out boost. Boost Additive is at 65 and looks like I only get about 12psi. Unless I am reading it wrong.. (Logs attached)

Is it possible to do Map 3 as Map 1 boost levels and Boost Additive value ads on top of that?

With a tune I was running around 22psi (probably not reliable imo). I'd like to be around 16-18psi with JB4 if possible.

Thanks

The target is around 15psi, but without an EWG connector to drive boost to target it's going to make whatever the factory dutycycle tables allow.

I know its hard to install. But I can do it.

Can I buy the EWG connector? Or is it not available for MINI?

[Terry @ BMS]

We have not done much work on that front. A few have bought them, then ever hear back on anything.

[johntotah94]

Will the software auto adjust if I connect it? Or do I need new firmware?

Will "JB4 F Series EWG Add On Connector BMW B48/B58" work? I can figure out how to install and report back with logs and such.

Will order today if you confirm it works. Thank you.

Can we update to this firmware test 1 attached or is it specific to the meth issue. I am in the process of installing meth awaiting charge ***** for the grand tourer. EWG does work on the b38/b48 ; may improve low end torque as in my case.

[Terry @ BMS]

Yes anyone can load the test firmware if they are having a WMI issue.

[johntotah94]

Still a few occasional runs with no flow. Changed min boost to 4psi and seems more reliable for now.

Can I order EWG Connector? Or bad idea?
