Since there are several owners running the JB4 with more people adding this mod on a routine basis, I thought it would be a good idea to post map profiles in one place to help others who have just bought or are about to buy a JB4. I think most people would like to see how others have set up their profiles by rpm or gear, what octane fuel they are using, and any associated mods that impacted their choice of profile settings.

Good idea or no?

I think many still don’t use map6 but here’s mine. It’s been ~10 months now and haven’t changed any setting since


1500=2
2000=2
2500=3
3000=4
3500=4
4000=4
4500=4
5000=4
5500=3
6000=2
6500=1
7000=0

Edit: this is on q50 RS, 93 octane

Greatly appreciated to see the maps others are running since I plan on doing the JB4 by the end of the month.

I'm still on stage 1, but based on the turbo maps from Stillen and formulas, this seems to be a good map, and I would love anyone who has a RS to try it out and let me know. I am holding off on the JB4 upgrade, but might do it if people say it works well. (Not sure oh the RS would do with a +5?)
1500=0
2000=1
2500=1.5
3000=3
3500=4.5
4000=5
4500=4
5000=4
5500=3
6000=2
6500=0.5
7000=0

Mine is very, very similar to that. I'll post up a pic in a bit, as well as some logs from some "spirited" driving vs an SRT8 charger last night so you can see how it performs.

Good start!


Make sure to note RS or SS and what octane number fuel you are using with the map you post. Don't want someone with a RS to plug in another person's SS map and end up with excessive boost pressures or use a map that's for a fuel octane number greater than what they have available.

For reference:

The JB4 maps are currently as follows:

Map0​ - JB4 disabled

Map1​ - 4psi peak

Map2​ - 5psi peak

Map3​ - User Adjustable fixed boost map (similar to Stage1) where “boost safety” setting on the user adjustment page determines boost added across the power band.

Map4​ - Valet map (reduces boost 6 PSI below stock)

Map5​ - 6psi peak

Map6​ - User adjustable by RPM map using settings on user adjustment page. A setting of 5.0 would request 5psi over stock at that specific engine speed.

Map7​ - 7psi peak

Note that DWP which is used on Stage1 to adjust throttle sensitivity is not used for this purpose on the JB4 and can be left at 0. The JB4 instead reads gas pedal input and other engine data via CANbus to scale boost as function of how far down you press the gas pedal.

Map5​ - 6psi peak

Map6​ - User adjustable by RPM map using settings on user adjustment page. A setting of 5.0 would request 5psi over stock at that specific engine speed.

Map7​ - 7psi peak

Regarding the maps, if you upgrade the JB4 to the latest firmware: JB4_Q50_OBDII_3_T1, then map 4 is a valet map which reduces boost 6psi over stock.

Good call. How do you check which firmware version is currently installed?

In my RS, I run either map 6 or map 1 depending on my mood... and whomever is next to me at the light
;)

Here's my map 6:
2.0 '1500
3.0 '2000
3.0 '2500
3.0 '3000
3.0 '3500
3.0 '4000
3.0 '4500
3.0 '5000
1.5 '5500
0 '6000
0 '6500
0 '7000

Tapered to 0 at higher RPM's because of this: https://blog.stillen.com/2016/12/to-infiniti-beyond-analyzing-the-vr30ddtt-turbos/



Here are the default map 1 settings:
3.0 '1500
3.5 '2000
4.0 '2500
4.0 '3000
4.0 '3500
4.0 '4000
4.0 '4500
4.0 '5000
3.5 '5500
3.0 '6000
2.5 '6500
2.0 '7000

I only have the BT kit, and using that: connect to the JB4 -> settings -> user adjustment settings, then scroll to the bottom and the FW version is in the "read only values" section.

Valet mode allows for 6 PSI boost over stock? Isn't that the opposite of what you want for a valet? I'd want it to be zero boost LOL.

Probably means 6 PSI reduction in boost from the stock profile? I think I'll label that "Wife Map" since I won't let a valet drive my car.

I believe that you misinterpreted. Reduced 6psi over stock, so for a RS, 14.5 - 6, or 8.5psi.

Whoops! Of course. My fault there. ;)

There's gotta be some more profiles out there! Anyone? Bueller? Bueller?

When posting profiles, please remember to post which engine and what octane fuel you're using with the profile.

I don't believe you can input boosts other than in whole numbers..... the app won't let me do so.

It would be nice if BMS would be consistent in their firmware labeling. The firmware listed on the website is: JB4_Q50_OBDII_3_T1. When accessing the firmware version in the JB4 app, it will show the firmware in this format: 50/3//5.

50 = Q50/Q60, 3 = firmware version 3, 5 = JB4 board type. They should date the firmware version also.

Subtle changes that don't show up in the firmware version format of 50//3//5 will be labeled as T1 - T199 at the end of the firmware version as listed on the website.

I have version 50/3//5, so I'm assuming it's current and equivalent to JB4_Q50_OBDII_3_T1

Are you sure? It absolutley works for me, and many others.

If you've updated the app and have the latest firmware, you might want to ask Terry/the JB4 developer dude what's up.

New JB4 User

As stated - Thank you for the info and I'm a new JB4 newbie.

2018 Q60 AWD SS Lux, White, White interior, emblems stripped, tinted. Nice clean ride. Running normal 92 oct pump gas.

Installed a JB4 with a REV3 BlueTooth kit for remote communications. Had terrible times pairing with my iPhone7S. Contacted BMS and Donnie was awesome with support. He downloaded a beta version upgrade for the mobile app and it solved my connection issues.

Then, I didn't have functionality issues with the various CANbus displays on the app, or logging features. After watching a youtube video that said the BlueTooth "did it all", I learned the hard way that I still had to hard wire the OBDII connection through the firewall. FINE I did that. (And thanks go again to Ando at BMS for helping me out.)

So now - I've run MAP0. I've run MAP1. I've run MAP7. There's a difference, but my butt dyno isn't registering the gains I'd hope'd for. But to be honest, I'm not at the track and I do city driving and can't honestly mash the pedal at every light.

Being new to the software, and no documentation, it looks like MAP6 is the only one you can dial in boost at given RPM levels? If I'm normally driving around town at 4,000 RPM or less, wouldn't I want to crank boost through this range for a snappy car? I never get to open it up unless I get onto the Interstate, which is rare. (Or if I want to get pulled over in town for stop light racing.)
