Hi i have fitted an HKS FCD to my 92 wrx i am using an apexi boost controller.the fcd worked for a while then started cutting again i have it wired properly but when i check the voltage on the live wire it is putting out 12 volts i know it only meant to run on 5 volts could i have damaged the fcd,the car runs fine with the fcd on but it cuts some times and not others.can anyone advise on correct voltage and settings of the fcd i had it set on 10 on the fcd.
