Loud clicking in sonenoid valve after installing PFC ECU
 

Hi guys,

So I bought an Apexi PFC ECU, and after I connected it to my car and turned the ignition to ON a very loud and continuous klicking sound is coming from the "wastegate control" Solenoid valve (SEE PICTURE BELOW). The clicking continues when I crank and start the car as well. When I switch back to stock ecu , or AEM EMS ecu, (and i turn ignition to ON) the clicking is not there. When I take the connector from wg-control solenoid (that is clicking) and switch it to the one next to it ("turbo precontrol") , the turbo precontrol valve makes that super intense and loud klicking noise. the problem is not the solenoid valves but the signal being sent from the connector.

Does anyone have any idea why this is happening? Is my PFC ECU broken , or is there a setting I need to change for it to stop?? Hope you guys can help.

Thanks in advance

PFC new or used, if it is used reset it. What map sensor is installed in the car? What map sensor is selected in the PFC.

Yes the PowerFC is reset. I use oem map sensor and the engine is stock.

What is the boost reading on the commander, key forward car not running?

^If it's not around -15 to -30 something just ain't right :)

Solution; I tried to connect another Power FC from a friend of mine with stock twin turbo setup, and the clicking was not there. So after testing it with AEM EMS; Stock ECU and an other PowerFC to see that they do not make that clicking noise, I concluded that there is something wrong with the ECU unit. So I was refunded my money back.

Did you return it? I repair PFC, if you still have it and want me to have a look at it
