Stage 1 Map Guide:

Map0: Stage1 disabled
Map1: Default performance map, 3psi over stock
Map3: Custom Target Map, select desired maximum boost over stock under "Boost Safety" user adjustment setting
All other maps and settings are unused


The idea behind the Stage1 is an inexpensive and easy to install/remove product that provides substantial gains with minimal headaches and trade offs. The Stage1 manipulates the ECU boost control signals allowing us to modify boost levels, but does not manipulate the ECU manifold boost reference, allowing it to properly map timing and fueling for the higher boost levels. The end result is something that runs as smoothly as stock only with higher boost targets under heavy throttle.

The Stage1 is not intended to provide the same maximum power gains you might get with a full custom ECU tune. Although based on today's dyno testing, the initial results for the Stage1 are still quite impressive. We envision a quick installation product that can be used with the factory tuning and even with aftermarket flash tuning for those looking raise boost a little in conjunction with higher octane via E85 or race gas.

For these tests we used a 30% E85 mixture, mixing in 5 gallons of E85 to a full tank of 91. Next round we will test 93 octane. With the stock tuning we were able to make ~320whp. We then used the Stage1 tune to test progressively higher boost levels, adding 4psi, 5psi, 6psi, and ultimately 7psi over stock. To my surprise each increase in boost resulted in a fairly steady increase in power, indicating plenty of tuning room within the platform.

How to connect and change map/boost level:

Quick directions:
1) Turn car on
2) Follow directions above to connect using either JB4 Mobile or BMS data cable
3) Once connected select map3 in drop down on logging page
4) Enter desired boost target on user adjustment page under boost safety and press save. Valid range is 0-8psi.

Stage1 user adjustment: Added option to adjust pedal to boost mapping using "Default Wastegate Position". Default value is 30, which represents 3.0psi. Below 3.0psi boost mapping is factory, above 3.0psi boost mapping is altered. Higher values may provide smoother but less powerful performance. When looking at your Stage1 logs DME BT represents the boost over stock. As you lower DWP you will hit your "over stock" boost target more quickly in the power band which may feel abrupt. If you raise it you'll hit your "over stock" boost target further up the power band which may feel smoother. If you raise it too high you'll never hit your full "over stock" boost target. During development we found 30 to be the best compromise set point and thus it's the default. It is now adjustable on map3. Probably best to avoid going below 10 or above 50.

Firmware:

There are no firmware updates for Stage1. DO NOT attempt to update firmware!

JB4:

JB4 Mobile Smart Phone wireless connection directions Click here
BMS data cable hard wired directions and software Click here

The JB4 is available as a complete system or as an upgrade kit to the Stage1 tuner. It adds CANbus control and other features to the Stage1 tuning allowing multiple maps based on expanded engine criteria, smoother partial throttle performance, additional engine safety systems such as lean run or over boost, more advanced logging for those wanting to experience with different fuels and E85 mixtures, boost by gear to improve traction, and much more to come via free firmware updates.

JB4 Install Guide: http://www.burgertuning.com/instruct...b4_install.pdf

JB4 Firmware:

Firmware updates are optional and loaded via either JB4 Mobile or a BMS data cable. We use updates to add new features, fix bugs, and make performance improvements, as documented in the firmware notes. Only the newest (highest number) firmware update is required as each firmware contains all previous updates.


Download using the new internal firmware database within JB4 Mobile or externally by clicking this link.



JB4 Maps as of v8 firmware:

Map0 - JB4 disabled
Map1 - 4psi peak, default map, 91+ octane
Map2 - 5psi peak, slightly stronger, 91+ octane
Map3 - 5.5psi peak, suggested for 93+ octane or 30% E85 mixtures
Map4 - 6psi peak, suggested for 93+ octane or 30% E85 mixtures
Map5 - 7psi peak, suggested for 100+ octane or 30% E85 mixtures
Map6 - User adjustable by RPM map using settings on user adjustment page. Setting of 5.0 would request 5psi over stock at that specific engine speed.
Map7 - Progressive WMI integrated map, boost profile under WMI flow adjustable on WMI page.
Map8 - Low boost VALET map (200hp simulation!) -- Auto selects when in ECO MODE.

User Adjustment:

While there are a lot of options only a handful should be changed outside of technical support:

Boost by gear: Setting a value in max boost 1st, 2nd, or 3rd will reduce the boost target in that gear by that amount. So setting 5psi in 1st will reduce 1st gear boost by 5psi, dramatically improving traction. For traction limited cars feel free to play around with the setting to find an option that works best for you.

Boost safety: This is the maximum boost before the JB4 disables itself, it should be set a few psi above your normal boost target. The default value of 20psi is usually a good setting.

Map6 boost values: Allows you to enter a customized boost profile. You'll enter only peak boost over stock here, so 6.0 means add a maximum of 6psi over stock, at that RPM point. The JB4 will blend this request with pedal input, engine temperatures, etc, to provide a smooth mapping. Generally this is only used for advanced customers who are able to read their logs and looking to make a map less aggressive than our off the shelf maps.

Optional fuel control wires:

Dyno Test: N54Tech.com - International Turbo Racing Discussion - View Single Post - Infiniti Q50 3.0t VR30DDTT Red Sport and Silver Sport BMS Stage1 JB4

Cliff Notes: Short fuel wire w/ resistor goes in spot 21, long wire goes in spot 20, and both wires then posi-tap to the white signal control wire in the primary o2 sensors. JB4 v6+ firmware required, to enable fuel control set FutureUseD bit0 on.

Options (FUD) bit selections as of v8 firmware:
fud.0 - Enable fuel control wires
fud.1 - Test AFR algorithm
fud.2 - Disable warmup safety
fud.3 - Don't use
fud.4 - Disable over boost, run lean, fuel pressure safety
fud.5 - Disable EWG offset
fud.6 - Vehicle is an RS
fud.7 - Linear pedal input

Firmware notes for posterity

JB4_VR30_OBDII_8:

1) Changed valet map from map4 to map8, changed WMI progressive map to map7, changed previous map7 race gas map to map5.
2) Adjusted ECO mode to force map8 VALET map when selected
3) Added communications to transmission to read gear, adjusted boost by gear to use actual gear instead of speed
4) Increased sampling rate of analog sensors for smoother performance
5) Enabled additional inputs/outputs for upcoming electronic wastegate (EWG) control.
6) Enabled boost control PID for upcoming EWG control.

JB4_VR30_OBDII_7:

1) Adjustment to fuel control mapping to add more fuel at higher RPM
2) Added support for BMS WMI kit under map8
3) Added linear pedal mapping option under FutureUseD Bit7. Turn on to smooth out boost targeting as a function of gas pedal input.
4) Added custom fuel mapping option under FutureUseD Bit1. Turn on to manually adjust "fuel enrichment" offset by RPM. Default values would be 50 across the board. Not suggested for most customers to play around with or touch this.
5) Fixed bug with false AFR reading during decel.

JB4_VR30_OBDII_6:

1) Added support for JB4 fuel control wires. To enable install wires to JB4 and set FutureUseD bit0 on. Once enabled you'll see "fuel enrichment" dynamically adjust in JB4 logs as it drives AFR up to the revised targets. Setting bit0 on WITHOUT the fuel wire will not negatively effect anything, but AFR readings in logs will not be accurate.
2) Added beep confirmation indicator when changing maps. Car should beep the number of map selected.
3) Added beep confirmation indicator when saving settings. Car will double beep when saving.

Gotta wonder what the Red Sport would do, or if the mechanicals are any stouter.

houbmw 05-09-2017 04:11 AM

WOW...thanks for the introduction to this platform.

1) Is the red sport a twin turbo compared to the 3.0 Premium being a single turbo? If you can, could you explain any major differences between the 2 models...from what I have read, the RED SPORT has extra intercooler I think.

2) Is the stock exhaust system extremely restrictive? I have seen on q50 and q60 forums that some companies are getting 20+HP and torque with just exhaust mods.

3) How is the transmission handling the power? I have a 3.7 2015 Q50 and it is a beast, but the transmission is horrible. I wish they had put the ZF 8 speed in it.

4) When you are adding boost to the 3.0 premium, how much is the stock boost...7psi? So when you adding 6 or 7 lbs of boost, total is 14/15lbs of boost...thats seems to be about what the Red Sport is pushing stock.

5) My lease ends in September and I am looking this month to get into a new Infiniti...It looks like it is better to get into a 3.0 instead of a Red Sport because of the optical sensors in the turbos. Would you state that tuning and modifications wise, 3.0 engine is better than the red sport?

Thank you again...I am looking forward to working with yall!

I hear it's roughly the same but with more aggressive tuning from the factory. But, looking forward to testing one in person one of these days.

Still think I'd stick with BMW and the B58 or upcoming S58.

It's an impressive platform and I think they also lease well like BMW. I'll stick with BMWs for my personal toys but the Q50 tuning market is going to be significant.

Was only a matter of time before the GT-R tech filtered down. Shame the only available transmission is garbage though.

Infinitis 7 speed isn't that bad. I mean its not a ZF8, but its not a Ford AODE either. Its still worlds better and quicker than anything manual.

houbmw 05-12-2017 01:12 PM

The transmission sucks on this one...I have 43K on my 2014 3.7 Q50 and the transmission is the weakest link by far. Just my opinion...they could have went with something that handles a bit more torque unless they beefed up the internals somehow. This is the only thing hesitating me from getting into the Infiniti again, rather than go over to the 340i at a higher price.

Mike_L 05-12-2017 03:26 PM

I dunno. I haven't driven the Q50 I don't think (if I did it didn't leave an impact, cause I don't remember it). I did drive the M56 though when I bought my GT, which I thought used the same gearbox and it wasn't horrible. To each their own I guess.

Terry @ BMS 05-18-2017 08:26 PM

Was able to get a red sport in today to checkout and tune. Same Stage1 tune worked flawlessly! Factory boost peaks at 13pi... Tuned for 91 I let it peak at 16psi. We'll get this car on the dyno next week to evaluate potential gains. :drinking:

add911_11 05-19-2017 04:15 AM

Wow I am always interested in getting an infiniti in future... the price for Q50 Red Sport in Hong Kong is so tempting and much better then what BMW offers...

I only hope there are some well modded Q50 so to see how this beast could be turned!

Fast Intentions 05-24-2017 01:57 PM

This is awesome. The market would be HUGE for a infinit version JB4. I get asked everyday when it'll be available by my friends who have these cars, most of them all red sports Sutton waiting to buy it.

Terry @ BMS 05-24-2017 07:21 PM

Stage1 tunes are about ready to go. If demand is high we'll look in to Stage1->JB4 upgrade kits down the road. :)

That's great news! Gotta get this posted in the Infiniti Q50/q60 group. Except I can't do it, banned cause everyone catches feelings there lol

Fast Intentions 05-25-2017 06:24 AM

Terry get someone on the forums this **** will sell hot hot cakes!!
