Default 3.5 Bar N20 MAP Sensor setup? - 05-14-2019, 04:37 AM

Just really want to clarify what is needed to run the 3.5bar N20 Map Sensor on my 2013 N55 F31 335i....

The sensor itself is physically plug and play, but what about any calibration?

Im running a custom BEF with a JB4 stacked for use on map 3 for meth.

At present I have maxed out the OEM sensor at 21.5psi, so cannot target higher on map 3 for the methanol injection.

The MAP sensor plugs in to the JB4 loom, and goes through the JB4 before returning to the cars loom. Is it just a case of setting the JB4 to setting "1" for the N20 TMAP? Will the JB4 then rescale the signal before it hits the car ECU, or do I need to set the setting to "1" AND have my custom BEF rescaled?

Thanks in advance

Don't change anything in your BEF. Only change the value to 1 in the N20 Tmap setting as you described in your JB4

I installed the n20 tmap today and changed the value from 0 to 1 in the jb4, my question is regarding the boost failsafe psi level. Currently I have it at 21, do I need to raise it?
