Default WMI no flow at WOT - 04-01-2018, 09:39 AM

I have a 2013 335i with JB4, BMS intake, VRSF charge pipe, and VRSF down pipe. I installed the WMI kit yesterday and was able to prime/purge the line just fine, but at WOT I get a reading of 0 which I know is supposed to mean electrical issues. I double checked all connections today, even restripped and connected all wires again, checked pins 3 and 16, and purged the system once again. Everything is 100% correct, yet still I get a reading of 0 and no flow at WOT.

Signal scaling is set to 60 and boost additive is set to 40. Activation PSI is at 12.

I need some help as I have no clue why the system isn't working.

JB4 log? Maybe you have a setting wrong disabling it.

On the WMI page uncheck all the E85 options, and make sure external trigger min RPM is set to 2000rpm. I'd also set min boost to 9psi.

Does external triggers need to be set to 1 for the min rpm to work?
