I wonder does anyone have damos for EDC 15C5.7 ? The car is AlfaRomeo 145 1.9JTD 105Hp, my own... I want to activate pressure control of the turbo. I found the switch, that enable this function (like in EDC15C2 PSA) and in live data i can see desired boost pressure now, but the Duty Cycle of the valve still remains 0%. No any errors related with this valve, although isn't connected... So any help be welcome.
Regards!

I have the same problem with a edc15c2 PSA

I activate the switch but I have no signal on turbo solenoid

I can see the pressure measured but 0% duty cycle of the valve... any ideas???

I think, that you case is simple... Maybe you can flash the ECU with 110 Hp dump... If ECU is physically the same of course.
But in my case, there is no ECU EDC15C5.7 for FIAT, Alfa and Lancia, that have this function by factory.

So, with compare between available damos, i found another switch (for type of LDR) and achieve some DC percents. Not proven yet, that have output in related pin, no errors without valve yet...

Hi, I worked a lot with an edc15c7 to adjust a bigger TC, and it was very difficult. I suggest you to change ecu with an edc15c7 and all cables,sensors ecc., or install a meccanics pressure controll.
