By default the JB4 ships on map1. For higher boost map, logging, firmware updates, and other features, you'll need a JB4 Mobile adapter for wireless connection to your phone or a BMS data cable for wired connection to a laptop.

Map guide as of v5 firmware (selected via JB4 Mobile/laptop interface. Map1 is the default map)

Map 0: JB4 disabled
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.
Map 4: Valet map, runs around half as much boost as stock.
Map 5: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications. May not be suitable for E85 mixtures due to high fuel pressure dropping. If using this map on E85 you should be experienced at reading your own logs and evaluating ignition advance and fuel pressure.
Map 8: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.



1) Revised logic for Options bit7 (more linear pedal mapping).
2) Revised boost scaling up in JB4 logs 0.75psi.
3) Revised fuel mapping 0.25:1 richer peak.


1) Changes to logging for 2L models. Water temp, road speed, and fuel pressure are now active.
2) Enabled WMI PWM control for those running large nozzles that need less flow at lower RPM.


1) Enabled over boost and run lean safety systems. Value "last safety" will be stored in the event of a failsafe for later analysis in the read only area of the JB4 user adjustment page.
b) Over boost safety: If boost exceeds value entered under "boost safety" on the user adjustment page (default value of 20psi) for more than a second under heavy throttle JB4 will revert to map0 (stock tuning).
b) Run lean safety: If air/fuel ratio in either bank exceeds 15:1 for more than a second under heavy throttle the JB4 will revert to map0 (stock tuning).
2) Revised CANbus to add cylinder 2-6 raw timing advance. Although early days we expect this data to further help customers when doing custom tuning, exploring the power limits of various fuels and modifications, and to become a backbone of the upcoming JB4 auto tuning logic we're working on. This logging can be disabled by setting FutureUseD bit4 on.
3) Added option for a more linear pedal input to boost profile mapping. The default pedal mapping is FutureUseD bit7 OFF, while setting FutureUseD bit7 ON enables the more linear input mapping.


1) Added double-PID fuel control algorithm which provides a nice improvement in dynamic AFR control over the previous single offset algorithm. In JB4 logs fuel enrichment reflects the bias for bank1 while "calc tq" reflects the bias for bank2.
2) Made a test adjustment to the passive delete function. Some have reported a momentary "pause" during startup cranking. Reversed change in BETA3 as it didn't fix problem. If you have this issue pressing ignition button once before starting car may help.
3) Adjusted JB4 interface such that fuel bias values no longer need to be entered for fuel control to be active. They can all be set to 0, or left at previous settings, because they will be ignored unless you enable "manual" AFR tuning under FutureUseD bit1. NOTE if not using fuel control wires no changes are needed but logging of AFR will not be accurate unless setting FutureUseD bit 0 on.


1) Fixed bug with boost by gear kicking in under low throttle, will only phase in over 70% throttle now.
2) Revised pedal input mapping for smoother and stronger partial throttle performance, and less throttle closure during shifts.
3) Adjustments to map boost profiles.
4) Revised fuel control algorithm.


1) Revised boost by gear logic for improved traction on RWD vehicles. You can now set gears below the factory boost levels if needed. For each gear enter the amount of boost reduction you want. For example, 8.0psi would reduce boost by 8psi in 1st gear. In our development non-LSD GT we've been testing 8psi in 1st and 2psi in 2nd with good success.
2) Added progressive water/meth map map8. Requires WMI integration using a BMS FSB to run the pump & solenoid. Once installed WMI is enabled when map8 is selected and the JB4 progressively controls WMI and boost targets as a function of WMI flow. The only safe way to run WMI.
3) Adjusted map7 to match map5 but hold boost stronger to redline for heavily modified cars.
4) Added logic for IAT remapping which provides direct ignition timing control. Requires you to add a wire within the JB4 harness itself. Will post more on this as we further evaluate it.
T5) Added fuel pressure logging under FP_H.

JB4 User Adjustment Settings as of v7 firmware:

Boost by gear: Enter amount of boost reduction in 1st, 2nd, or 3rd gear. Very useful for improving traction on RWD vehicles. We generally run 5psi in 1st, 1psi in 2nd, on our GT on stock tires to avoid wheel spin during launch mode. This reduces boost in 1st gear by 5psi, and reduces boost in 2nd gear by 1psi. You can reduce boost below factory levels as needed.

Fuel Bias: Used to fine tune fuel control. As of v7 firmware these settings are not required and only enabled if FutureUseD bit 1 is enabled. Values of 80 across the entire power band will match the internal default mapping, going lower target a richer air/fuel ratio while higher will target a leaner air/fuel ratio.

Map6 Boost: 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.

FutureUseD BIT settings as of v7 firmware:

bit0 - Turn on to disable JB4 fuel control or if optional fuel wires are not installed.
bit1 - Turn on to enable manual fuel control adjustment by RPM. Default values of 80 across will match internal mapping. Generally not suggested unless advised by a tuner.
bit2 - Turn on to disable JB4 hot/cold water & oil temperature protection
bit3 - Turn on enable IAT/timing spoofing, requires wire added to JB4 harness and 6cyl setting for spoofing level
bit4 - Unassigned
bit5 - Unassigned
bit6 - Turn on if vehicle has an aftermarket flash map loaded to the ECU
bit7 - Turn on to run more linear (sluggish) gas pedal to boost mapping

Spark Plugs:

Only map1 has a chance of working well with the factory plug gap. We suggest closing the gap on the stock plugs to 0.024"-0.026", or replacing the stock plugs with Denso 5346 plugs and gapping them to 0.022".

For your convenience you can order the required plugs, gapping tool, and magnetic socket from BMS on a $100 combo price: https://www.burgertuning.com/collect...iri-spark-plug

Fuel Control Wires:

These add on wires attach to the JB4 harness and your vehicles sensors to give the JB4 the ability to directly change the air/fuel ratio. The factory tuning runs in the 10:1 range and leaning that out to 11:1 has proven to be worth significant power at higher engine speed. Note these are preinstalled on the JB4 harness now so only need to be attached to the o2 sensor signal wire to enable.

No setting changes are needed to enable the fuel control wires.

Forward video to 4min for systems already equipped with fuel wires to see how to attach them. For 3.3L they attach to the o2 sensor signal RED wire. For 2L applications only the longer wire is used and it goes to the primary o2 sensor signal WHITE wire.
