Map 1: Default performance map, 3psi peak request over stock (suitable for all 91+ RM2 fuels)
Map 2: 4psi peak request over stock (91 -93 suggested)
Map 3: 22psi absolute boost target (93 - E30 suggested)
Map 4: 23psi absolute boost target (E30-E40 suggested)
Map 5: 25psi absolute boost target (E30-E40 suggested)

Note to properly delete fault codes the car must be in diagnostic mode first. With your foot off the brake press the ignition button 3 times fast. All lights will appear on dash.

For those helping test the fuel pressure add on connection: Green goes to 11, and black goes to 23 right below it

Are those dragy numbers on 93 octane? Under 11 seconds with JB4 only!?
December can't come soon enough.

It did 10.8@126mph on E40 blend.

Will the JB4 be compatible on 91 octane at 4500 above sea level?

I'd be interested to see the power gains on 91 Octane/Map 1.

Jb4 Installed on New X3M Comp
 
Hey guys, I just installed the JB4 Beta in my new X3M Comp. :happy
Headed out to get some E85 now. I'll let you know how it runs.

Yes map1 is fine for 91 octane, even at elevation.

Amazing. 10's with just a tune.

Is there no better place to run the OBD cable though? Looking at the directions, you have it going through the drivers door seal. That seems like it would get pinched. No grommets on the firewall you can use?

Steve is the go-to person for that question as did the install. :)

NJCarGuy 11-20-2019 04:59 AM

There's a hole in the firewall with a sticker over it. OBD cable passes through with ease.

Mike_L 11-20-2019 03:08 PM

Nice. I was just fawning over one at the dealer. Made my choice so much harder for this spring/summer... X3M Comp or M550 LCI? Same price, only $40 a month difference in the lease. 503hp vs 523hp..... Going to have to see what the JB4 does with the M550s new motor.

Any Dyno Data ?

MarinoB 12-22-2019 03:06 PM

Break in service complete...about to order my Xmas gift!

Spent a few hours this am with Steve on the dyno dialing in some firmware changes. Initially on 91 octane then Steve poured in some E85 to get it up to E47. So much tuning potential on these! Can't wait until the S58 finds its way in to the new M3. :burnrubber:

Mike_L 01-28-2020 12:05 AM

Looks like these are at least 10% underrated from the factory. Probably more since this was on ****ty 91 octane. 503hp my ass. 550+ is more like it.

Payam @ BMS 01-28-2020 09:19 AM

Man 660whp from stock turbos. I can't wait until the new M3/4 are out with the AWD system.

FBO E85, 9 sec car

Wow. This is bananas! May have to get a G80...I can outrun the ugly in it!

Terry @ BMS 02-01-2020 09:43 PM

lol

andym3100k 02-01-2020 09:48 PM

Canít wait for the new M3/4 to come & start turning up boost to it 💪🏻💪🏻💪🏻

MetzgerGt1 02-26-2020 05:15 AM

When is the next round of S58 updates expected? Anything in the works?

Juiced46 05-31-2020 09:13 AM

Are there any dyno #s on 93 octane only?

Also can maps 3 and 4 be used with good quality 93 octane?

We've been working on stuff with people via email since the platform is still so new. Email me logs of how it's running and we can see if any of the changes might benefit your situation. :drinking:

RoyB 06-16-2020 06:31 AM

Installed everything and the car limits power @ 3500 rpms. I emailed support and Ando requested I update firmware and log 3rd gear. I did and problem persists. I am running Map 1 on 93 octane.

Any ideas? Power feels like it's increased over stock until that point. Then it cuts power and bucks like a manual car in the wrong gear.
