Default M3/M4/M2C S55 JB4 Anti-LAG setup - 05-08-2020, 02:58 PM

Finally getting around to writing up some directions for this. We plan to offer a kit down the road but for now I'll just post it as a DIY for those who want to dive in and start playing around.

Requirements for S55 Anti-LAG:

1) A BEF with the proper table adjustments. We add "AL" to the filename of our BEF to indicate the changes required have been made.
2) Solder a resistor to the JB4 control board, see photo below.
3) Add a wire to the JB4 harness between spot #20 on the JB4 connector and spot #2 on the BROWN MAP sensor connection. DSUB pin (standard, not high desnity) required for this. No resistor is needed in the wire. Posi-tap for MAP side connection is the easiest method.
4) Latest JB4 firmware with anti-lag logic enabled by setting DWP = 90.

What changes need to be made to the backend map? I'm really interested in trying this with my F80Paul map, though it's via BM3. He's not sure what changes are needed, so if you could provide them then it would be appreciated

I had see several cars running with JB4 no matter which flash or plattafom. Not 100% sure for antilag if could be done on other different flash from BMS
