It works flawlessly, I'm using Map1 as I have no other modifications.

Stay tuned for review, pics and performance analysis

What model JB4?

Also, franzzz did you ever post pics, review and performance analysis?

[franzzz]

You find video on this thread.

In the same road :
0-60mph stock : 5.3 secs via mlaptimer
0-60mph tuned : 5.0 secs via mlaptimer

I put the Stage 2 on my AH3 after installing the Dinan CF intake, ran Map 2 after getting comfortable on Map 1, and blew my charge pipe. Luckily, I was close to home and drove home under electric power (whoo!) with no problem. I got an ER charge pipe, which is sweet, put it back on Map 2 for a bit and no problem. I added the Meisterschaft mid-pipe back and changed to Map 5 and have had 0 issues (aside from traction) since.

Charge pipe is a must with map 2 or higher power

Hmmmmm on my acceleration video I timed 11s from 0-170 (stock). So I'm not sure if the BMS Stage 1 is worth it for the AH3.
Have you made a new video with the new mods?

[franzzz]

This is stock AH3
0-180 14 sec

In your test the road is not FLAT.......

[franzzz]

1700Kg weight
19" Wheels
Stage 1 with around 380Cv

[franzzz]

Without Stage1 0-100Km/h max 5.2 sec

This one is doing 12 from 0-160.
Mine is doing 11. Road was flat for sure. Will make a new one in daylight soon

Wish there was M Laptimer for Android :/

[franzzz]

Without laptimer is not possible to see real performance of your car

+ One day, drive malfunction happened. Car just lost all the power, and it does not want to go over 30 mph. I parked my car, called BMW road assistant for towing and planned to directly go ahead to dealership for service. While I am waiting, I uninstalled JB4, restarted and car works fine.

It just scared me. Probably I will sell JB4 for now.

After 3 days, my car was serviced by BMW. They said they had to replace fuel pump. Covered by warranty fortunately.

A number of AH3 owners have had fuel pump failures, so not the JB4.

Low pressure pump or high pressure pump ?

Technically it a sensor on the low pressure fuel pump that fails, throwing an error code that throws the car into limp mode.

BMW does not have a sensor replacement so one has to swap out the entire fuel pump due to he sensor failure.

Hi, JB4 map 5 here with Akrapovic exhaust and BMC air filter on the intake side, no issues to report, no codes anything. I have the bluetooth extension on JB4 to monitor everything and switch maps easily ln the iphone.

So you didn't need a new chargepipe or downpipe etc? I thought those were required with JB4 if you didn't want to blow the OEM parts and bit throw error codes?

Also, seeing yours is a 2014, do you have an EWG?

Finally, off topic, do you have the automatic Anti-Dazzle Halogen Headlights?

[Lancelot]

JB4 allows for progressive mods, map 1 is designed for added performances on a fully stock car for instance, map 5 is auto learning and will adjust to engine parameters, probably benefitting of the exhaust/intake mods i put on. I don't plan on other engine mods for now, i've got the power I need.

Things I like about JB4 is:
- it uses all engine parameters to determine appropriate boost - gear, rpm, oil temp and more than that, protecting the engine in lower gears, or when it's cold.
- it can evolve with my future mods if any
- it's got bluetooth extension
- and a wide community of users for support

Indeed i have EWG, it's a 12/2013 production / 2014 Model Year car.

And yes I do have anti dazzle too.

Replying to a pretty late thread here, but I can't tell if I need PWG or EWG JB4 for my '13 AH3, how do I tell(I'm pretty sure it's PWG b/c of its model year but I want to be sure before I buy)?
