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.
