HSF3 EVo 9 and AEM series 2 idle Issue

[DJ]

Guys

I have been using the system for some period of time, but now noticed that after turning the system ON, the idle starts to bounce and seems that some Idle parameters start to di funny things,

I used the hsf 3 wiring for evo 9 jdm and usdm for power supply, injector, I used switch No. 5 on Pin 54 for ground loop input for secondary map

Funny thing is that AEM ems shows this pin as a switched ground available, as it was the power steering pressure switch (oem pinout ecu diagram)

Its like the Idle speed controller starts to open up more and messes the idle

let me know if you have got similar issues

My system is a direct port hsf3

thanks
