What is menu 10 on JB4?
Menu 10 is the position the wastegate returns too when making less than 1.5psi of boost. Menu 11 is the gas pedal sensitivity start point. A setting of 0 runs zero boost up to 45% gas pedal input while a setting of 5000rpm runs zero boost up to 5% gas pedal input. 100% gas pedal input is always full target.
What are the JB4 maps?
The JB4 is a programmable computer that attaches between the ECU and vehicle sensors allowing it to adjust your vehicle’s tuning by tapping into areas of the factory flash mapping that are not normally available.
What is FF JB4?
FF Curve: The base PWM curve before the PID output is added in. We’ve programmed this curve within the JB4 as a function of boost target, pedal input, RPM, EGT, and some other smaller criteria. FF User Adjustable: A 0-150% variable that globally scales the FF curve up or down across the board.
What is FF wastegate adaptation?
FF/WG adaption adapts and learns over time, any value between 1-150 means JB4 “feed forward” function learning is still active. Reset the value to 60 and it may learn down after a while. If you are dropping RS3’s, your car is running fine.
What is fuel open loop JB4?
You JB4 should ship with a fuel open loop value of 40. The maximum you can go is 60. Increasing the value will lower trim levels by increasing rail pressure. Dropping the value will increase trims values.
How much horsepower does JB4 add?
How about up to 80hp to the wheels (100hp crank) on a completely stock car, up to 160hp to the wheels on factory turbos, or up to 350hp to the wheels on a fully modified car with larger turbo(s)? The JB4 includes a simple plug and play installation harness and is compatible with all ECU versions and transmission types.
Is the JB4 safe?
The JB4 is a relatively safe tuning system with extra systems built in to help prevent the ugliest outcomes, but it’s important to always keep in mind, more boost, more power, more risks. So always choose your performance map accordingly.
What is JB4 duty bias?
Duty Bias: The new user adjustment fields which allow adjustment of the FF Curve by RPM.
What is PWM JB4?
PWM = The additional signal, in percent, that the JB4 is applying to the boost solenoids. This is in addition to the signal applied by the DME (ECU). ECU PSI = the JB4 generated signal output that the ECU reads as pre-boost… to keep the ECU “happy”.
Is JB4 a piggyback?
JB4 is a piggy back system for tuning, basically controls engine paremeters from the ECU to the Engine. Its a rather dirty but functional way to tune a car.
Can you trace a JB4?
The JB4 intercepts it at the sensors so the ECU thinks its running stock. It’s not reprogramming the computer. All boost levels etc are marked the same on the stock ECU. There is no way to trace it if its removed.
Where is Burger Motorsports located?
Orders ship Monday-Friday from our warehouse in California, USA.
What does the jb4 chip tune do for a car?
JB4 is a plug & play chip tune available for turbocharged vehicles. The JB4 comes preloaded with custom tuning software and up to 8 maps for various fuel and modification levels. The JB4 installs between your car’s sensor and its DME/ECU (computer) and manipulates vehicle performance through these connections.
What kind of warranty does the jb4 have?
The JB4 installs between your car’s sensor and its DME/ECU (computer) and manipulates vehicle performance through these connections. Installs and removes without a trace. 5-year warranty.
What can you do with a jb4 mobile?
Not sure why these devices are so picky, but at least someone found a workaround. JB4 Mobile allows you to monitor multiple parameters of your JB4 equipped car at once. Parameters such as boost psi, rpm, fuel trims, air/fuel ratios, ignition advance, fuel pressure and much more are all available.
