New JB4 Firmware - 4/22 - With CanFlap

[Mike@N54Tuning.com]

I have had alot of questions about this so figured I would post here Enjoy the update!!

New Firmware

Software

Software and firmware are paired so you need both! You also need to have the JB3/4 USB cable to be able to update the JB4

Disclaimer
If you have no idea what the above means then don't do anything. Just drive and enjoy your car

1) Corrected 135i metric mode to properly reflect speedo input selections.
2) Lowered maximum FFPID value in 1st gear.
3) Added integration for CPS/SLD module including CPS charting.
4) Added "CANflap" commands to menu 4 options 4 (disable/go back to stock) and 5 (always open). This feature adjusts your factory exhaust flapper.
5) Added octane and oxygen sensor adaption reset commands to menu 4 option 7.
6) Rescaled FFPID function down 400rpm.
7) Added RPM by RPM global adjustment of air/fuel additive and CPS offset.
8) Complete redesign of data logging input functions for expanding user adjustable fields needed for #7.
9) Added "restore defaults" command to reset all user adjustable values (except map and meth settings) to the default values. Command is automatically sent following a firmware update to avoid firmware/setting compatibility issues.
10) Adjusted AFR output to always reflect leanest bank at any given time. Previously bank2 was always displayed.
11) If using external LM1 wideband FutureUseD=2 causes JB4 to use that value instead of factory widebands for all AFR use including internal safeties and nitrous trigger.
12) Default "exp1" logging parameter is now low system fuel pressure. Setting FutureUseD=3 outputs DME liters per hour consumed. Setting FutureuseD=4 outputs road speed in KMH.
13) Added iDrive radio auto on/off commands for testing. To enable set FutureUseD = 10. When engaging command mode via steering wheel controls iDrive screen should turn off. When exiting command mode iDrive screen should turn back on. In early testing it appears functional for 2009+ iDrive models only.
14) By default the spare external output (DB9/4) is now used for CPS integration. To revert back to external trigger use (n2o, etc) set FutureUseD=77. The normal external trigger has been relocated to pin 15 on the processor. If you need both CPS integration and nitrous integration you will need to solder a small gauge wire to the processor. Email for details.

Hey - just curious....is map 5 on JB4 the same as map 5 on JB3 2.0? If not, what is the equivalent on JB4?

[Red135]

I can tell you that it is not the same map, but I do not know what the equivalent would be.

Map 5 on the JB3 has not equivalent on the JB4.

Map 1 on the Jb4 is somewhere between Map 1 and Map 3 on the jb3

Map 2 on the Jb4 is close to map 7 on the jb3

Map 5 on the jb4 is an autotuning map, meaning the jb4 will change boost levels automatically to push as much boost as it can safely based on your mods. If you have lots of mods, you may push lots of boost. If you are close to stock, map 5 will run minimal boost.

i think you may have uploaded the jan 20th software...

No, map5 on the JB4 is the new autotuning map.
