JB4 4/20 alpha firmware with CANflap, CPS interface, and more...

Mike@N54Tuning.com · 04-25-2011, 05:23 PM

Hey guys,

BMS just posted the 4/20 alpha firmware and interface for those of you who are interested in helping test it. A full listing of changes is below but it includes the new CANflap feature. And for those of you testing the CPS module it now has full user/custom tuning adjustability. The JB4 is the only popular N54 platform to give you shade-tree tuners the option of setting up your own boost, air/fuel, and CPS curves! The firmware and interface are posted on BMS' forum.

Quote:

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 2008+ iDrive models only.

Not bad at all

Played with CANflap last night, worked perfectly.

chili36 · 04-25-2011, 07:19 PM

And the idrive "radio off" feature works nicely too!

@Mike,
Any release date for the final version yet? I do have JB3 but on V2, and want to jump to JB4 when its the final version. hopefully i don't have to play around with all of these setting, just plug and let it autotune.

FLoRiDa335i · 04-26-2011, 06:35 PM

i cant find the new firmware

I would not wait for a "gold" version. There will be lots of iterations, get it in!

+1

Work is constantly ongoing and I don't see it stopping anytime soon. We went public with the JB4 when we felt it was stable and solid, which it has proven so over the last several months.

Terry took off the Firmware link on N54Tech after 120 downloads or so in order to fix possible bugs based on Datalogs from the 120 that downloaded it.

Forcefed3 · 04-27-2011, 05:54 PM

Mike, any idea when it will be available again?
