Phantom Knock?

[I GOT RICE]

basically my safc is picking up knock while im idling the car, it starts off at about 1 or 2 then it reads 0 when i start driving but the more i drive it, the worse it gets (30-40+ while idling) until its reading knock while the car is moving not just idling.

the history goes that my 33 was imported as a non turbo but i bought the car with the turbo conversion. everything was swapped besides the brakes and gearbox. it was going all good until about 2 months ago when the motor blew on me and it was evident that the tuners who done my car f'd it up real good and fed way too much timing. i got a straight swap from hyperdrive but ever since i got it back i've had phantom knock. i told the guys at hyperdrive about it and they said they hooked it up and theyve read on there comps that theres no knock at all and that my safc is showing false readings.

anyone had similar experience?

anyone know how to resolve it?

I wouldn't trust an SAFC for accurate knock readings. Get it on a dyno, and get them to use the knock headphones, that will determine whether it's genuinely knocking.

yer they already did and they said that the SAFC is wrong and picking up fake knock. will this be an auto elec job to fix or can i solve the problem myself?
