Hey Fellow Canucks

If you guys don't know N54tuning is located in Ontario so we ship all our products from Canada so you have no worries about hidden brokarage charges or duties or expensive and lengthy shipping

----------------------

I just wanted to let everybody know that all new JB3s now ship with 2.0!

If you haven't heard 2.0 transforms the JB3 platform into a truly revolutionary product that is a huge improvement over 1.4 in terms of features, power, smoothness and overall feel. I included some explanation of the user interface and adjustable features below.

We also have the USB Cable available for purchase now!

Datalogging directions:

To being recording click “file” “connect” to establish communications with the JB3. If you fail to connect, ensure you’ve selected the appropriate communications port under settings.

If the RPM and other signals are moving around below you are recording. If you have stopped recording for any reason and want to restart or reset a log you can click “data logging” “start”. The interface will store up to 5000 data points. If you have samples / second set to 10 under settings this will yield a maximum of around 8 minutes of recording time per log.

At the conclusion of your runs/log, click “data logging” “stop and display” to stop recording and plot the datalog. Parameters can be added or removed from the display by clicking the “add” button next to each. If you want to save the log for later, or email to BMS, click “data logging” “export” “csv” and save the file. You can click “data logging” “open CSV” to study the log at a later time. All parameters will be always saved in the CSV regardless of your viewing settings.

Use the “data logging” “X Axis” menu to adjust the scaling or filter out non-WOT activity. With longer logs and slower computers scrolling through the display can be slow, so limiting viewable data to near WOT activity only can be a time saver.

Logable Parameters:

1) Pre-Boost. Boost pressure as measured before the throttle body. Generally will match manifold boost pressure like one might read from a mechanical boost gauge except in cases where the throttle body is not fully open. Such as during DTC intervention or loss of traction, sudden shifts, letting off the throttle at the end of a run, and over target conditions where the ECU throttle safety is kicking in. During these conditions pre-boost will spike up prior to the diverter valves opening. Scale is 0-20psi along the left of the chart.

2) RPM. Engine speed in revolutions per minute. Will roughly match your dash tachometer. Scale is 0-7000RPM along the right of the chart.

3) IAT. Air intake temperature post intercooler in degrees Fahrenheit. Scale is 0-20 = 0-200 degrees F along the left axis.

4) TPS. Throttle position / gas pedal sensor, 0% = idle, 100% = wide open throttle. Scale is 0-10 = 0-100% along the left axis.

5) MAP. Currently selected performance map. You can use the drop down to change maps while logging is active.

6) Fuel. Amount of fuel enrichment being added. Scale is 10-20 = 0-100% along left axis.

7) ECU PSI. The amount of boost the ECU is observing, generally 6-8psi during WOT activity. Used as the process variable for the PWM PID controller. Scale is 0-20psi along the left axis.

8) PID PSI. The minimum ECU PSI allowable for the given conditions. Above this value less PWM is required and below this target more PWM is required. Scale is 0-20psi along the left axis. It is normal for ECU PSI to float high above PID PSI under certain conditions such as part throttle indicating the JB3 does not need to supplement PWM at that time. As ECU PSI falls below PID PSI the JB3 must increase PWM to sustain target boost levels.

9) PWM. The boost solenoid/duty cycle/wastegate offset. Higher values indicate more wastegate closure initiated by the JB3 and lower values indicate less wastegate closure. This value is determined by the PID controller which is driven off ECU PSI and PID PSI and influenced by parameters under user adjustment.

10) Clock. An internal variable used by BMS. Has no significance to end users.

11) Timer. internal variable used by BMS. Has no significance to end users.


User Adjustment Notes:

Not all fields are currently in use/enabled. Refer to beta firmware notes as needed.

Tuning Setup: Allows map specific tuning adjustments. Currently only map 1 is available to be modified/customized. The settings under tuning will reflect map 1 no matter what map is actually selected. But they will only take effect if map 1 is selected unless otherwise noted.

Torque: Boost < 4500 rpm.
Power: Boost > 4500 added on top of torque setting.
Fuel: Amount of fuel enrichment over stock under boost. 0 = stock air/fuel ratios.
IAT Decay: Boost taper based on air intake temperature. 0 = no decay, 9 = map 7 levels.
Lagfix: Controls the default wastegate position during cruise. In the beta firmware, lagfix maps are set to 100, and non-lagfix maps are set to 0.
Bogfix: Controls the value of PWM during sudden manual shifts. Higher values hold more PWM, and thus more boost through the shift, but may make shifting feel abrupt or notchy. Set to 0 in beta maps.
Boost Limit: The maximum allowable boost before reverting to map 0. Boost must be exceeded for ~500ms during WOT to trigger a map change to 0.
Lean Cruise: Enables a feature that leans out air/fuel ratios during sustained cruising/off boost conditions, resulting in an additional 2-3mpg, at the expense of low throttle torque and emissions.

Global Settings: These settings take effect regardless of map selected, and are generally related to boost target modeling, or the "PSI PID" loggable parameter. All fields establish minimums that the JB3 then adds barometric, ambient temperature, and time under boost calculations to arrive at final values.

Min Target: The lowest allowable WOT boost target at lower rpm
Max Target: The lowest allowable WOT boost target at higher rpm.
Taper: The rate of boost reduction to redline once peak boost is reached.
Min PWM: The lowest allowable PWM under heavy boost
PID Gain: A general field for adjusting how aggressive the JB3 is in hitting its boost targets. For tuning nerds I and D are a function of P so you scale the entire system with this field.
Throttle Gain: Controls the resistance to positive boost swings. Too low of a setting results in sluggish boost response, but too aggressive can lead to boost overshoot.
Disable Pedal Map: Enables/Disables gas pedal mapping. If you never want to use gas pedal map switching and only plan to change maps via an external device or laptop, set to 1.
Future Use: Not currently used.

Methanol Setup: Global settings for enabling methanol output and failsafe.
PWM Enabled: Enables external methanol trigger, generally not used with CMGS or more popular controllers.
IAT Safe: Enables a software based methanol safety for those using non-failsafe kits. During safe conditions map entered here is selected. Not fully tested so leave set to 0 for now.
Meth Map: Enables a hardware based methanol safety for those using the CMGS and other similar flow sensor devices. When methanol is flowing within a window enables map selected. To trigger feed a 5v signal in to pin 15 of the JB3 DB25, or a 12v signal through a 10k ohm 1/4 watt series resistor.

Informational / Read Only: Values for reference only, can not be changed directly

Ambient Voltage: Barometric pressure reflected in a voltage format.
Firmware Ver: Version of firmware (HEX) file currently loaded.
Interface Ver: Version of the interface software currently loaded.
