Seems like the links to the product and mobile kit don’t work anymore.

Question Installed: map 1 logs attached - 08-04-2019, 07:19 AM

Installed yesterday. I’ll post a longer review with some thoughts/tips/suggestions in a bit, but I want to get some map 1 logs here as a first step for BMS to evaluate. Hopefully the logs are long enough to be useful.

In one sentence though, I’ll say that map 1 feels amazing. So far extremely smooth and pulls like crazy. Very pleased so far.

One question for BMS awhile...your initial post shows Fuel Open Loop as 30 for default value, but my mobile app shows 0.0, in case this matters. I don’t understand what that does, so I didn’t want to change it on my own.

After getting your feedback/approval/recommendation on map1, please let me know if it’s safe to log map 2 (I use 93 octane).

Congrats to your install. How is smoothnes? On 4th gear is it smooth from 3500 rpm to redline? No hesistation?

It's a setting we use to balance out fuel trims. These logs look OK but go ahead and enter Open Loop = 30 and grab another map1 log for comparison.

Default Map 1 fuel open loop 30 logs attached - 08-05-2019, 08:59 AM

Hi Terry,

Attaching two logs from map 1 with your recommended change to the fuel open loop (now at 30). As you can see, one was a highway pull and the other was more back road. If you need longer ones to properly analyze, just let me know.

If you can let me know your thoughts on these, and then a yes/no on trying a map 2 log, that would be great.

Still shocked at how hard this pulls on map 1. Very noticeable difference from stock. I think it really must tax the traction control and grip levels of the tires because even after doing these pulls at speed (3rd-5th gear), all I smell is cooked rubber when I park it and get out of the car, even leaving TCS fully engaged. That never used to happen.

Looks good to me, you can leave the open loop setting as is.

Default Map w log attached - 08-06-2019, 04:54 PM

Terry please see map 2 for analysis.

Initial feedback is that I didnít notice a real big difference from map 1.

Also at partial throttle it gets a bit hesitant/jumpy. Noticeably not smooth just like 30-50% throttle in 3rd or 4th gear. Reminiscent of Notabenexís. Didnít get a log of it, but figured Iíd mention.

Map2 seems OK. On part throttle grab a log of it next time and we can always check it out.

thoughts/tips/suggestion on installation? How long did it take you to install or did you have a shop do it? Thanks.

Definitely donít need a shop to do it. Takes 3 hours if you take your time and 1-1.5 if you move quickly and have done it before. Itís basically an hour plus the time fighting with sensors 1 and 3.

Tips:

obviously start with a cold engine

Use a magnetic torx so you donít drop the screws

Ask BMS for the few other videos theyíve made for sensors 1 and 3. They arenít revolutionary by any means but they donít hurt.

Have someone help. Four hands are helpful for sensors 1 and 3. Someone can finagle a long flathead in there to press the female part off while someone can get their hand cut up and curse while pressing the locking release tab.

Personal tip after seeing water damaged boards is, RTV well around the outside of the JB boxís ring gasket and also the looming grommet. And mobile connect wire exit. That should water-tight it.

Also a stupid little thing but itís not mentioned in the install...your OBDII protective cover will flap around and be annoying with the JB4 plugged in, so carefully pry that off and save it somewhere and itíll solve that minor issue.

Thanks a lot for the tip! I gave up from sensor one and took it to a shop which still took 3 hours with two techs. BMS, could you please point me to videos regarding the removal of sensors 1 and 3? Thank you!

Hi Team - just wondering if there's any progress/update on whether there will be in-dash controls with this merc version of jb4 platform, similar to the controls in the bmw platform?

Particularly interested in whether we can keep flaps 'always open' like we could in the B58(F30) bmw version of the jb4?

Thanks!

We're definitely working on it. It's tricky because we can't find an OEM tool to let us reverse out the command we need. But once we get them we'll add them to our entire MB C platform lineup via free firmware update.

By “tool“ do you mean a line of code or do you mean a physical tool? It’s not OEM, but many cars (like mine) are running the module from ASR that plugs into the wire for the flaps (in the trunk) and lets you override the flap closing and have it open full time. (It’s brilliant, by the way). Would getting one of those modules perhaps give you the info you need on what signal to send and control the flaps?

No because this tool is physically intercepting the signal (like the JB4 does) and altering it, I need the commands to do the same behaviors via the integrated CANbus system, to recreate the features we have on our BMW JB4 system.

So for an example an OEM tool you plug in the OBDII port that lets you test the exhaust flapper open or closed.

Gotcha. Ah well, figured it was worth mentioning in case it was something you could use.

Installed my JB4 tonight and went for a spin - wow!

Initial quick review:
Map 1 - not bad but looking for more ...
Map 2 - found it!

- Map 0 felt like stock of course.
- Map 1 was noticeably faster, more power, tires spin more easily and throttle is responsive. But I definitely did not buy this thing for map one.
- Map 2 was the same but even more power. Feels close to my old 548whp N54 535i, but power delivery is more midrange which is nice.

Log of map 2 is attached, BMS can you take a look? Looked good to me but interested in input.

I plan to try out map 3 this weekend! - after I swing by an E85 station, probably do a 20% mix to start and see how it logs. Expecting good results

I didn't notice any hesitation or odd behavior at idle, part throttle, or full throttle on any map. It did do a very slight stumble when I switched from map 0 to map 1 on JB4 app with engine running the first time but was not concerning. I switched maps after that with engine idling and did not notice it again.

Over all I'm very pleased so far! More to come ...
