This brief article explains the importance of using a JB4 even if your BMW is already Flash Tuned. It specifically explains N54 applications but it mostly applies to all engines.
1- Advanced Safety system
If boost exceeds your safety settings, the JB4 reverts to the stock map
If AFR is too lean (15% variance), JB4 reverts to the stock map
Extra safety for Port Injection and WMI
2- Absolute Boost Control System
JB4 targets an absolute boost level where boost is always the same (Independent of external factors)
JB4 has ability to set max boost per gear
JB4 automatically tunes Wastegates and fuel trims
Autotune maps that gives max safe power based on mods, fuel, and IAT (Intake Air Temperature)
3- On The Fly Changes
Boost Levels
Max boost per. gear
Gauges
4- Better Feedback for the Driver
Ability to change ANY settings, map, gauges using the JB4 app (on phone) without the need for laptop connectivity
Ability to monitor real time boost, AFR timing, knock, and meth flow
Ability to data log and email it to BMS using the mobile app (without the need for any cable)
Ability to record data, 250x per second
5- Complete Tuning System
Eliminates need for additional modules
No lift shift
2 step
Anti-Lag
Port Injection Control
Flex-Fuel sensors
Water/Methanol Control
Ability to work as a cohesive unit rather than have multiple modules working separate
6- FREE Upgrades and Support
Lifetime Firmware Upgrades and Backend Flashes
Free support from the BMS team
7- No Change In DME
All DME table values stay intact
JB4 adds performance and safety while keeping DME 100% in charge
Thank you to 'BMW Fanatic' on YouTube for the awesome explanation!
