Excessive knocking at low rpm/light throttle

Post by teamXXXrob »

I've been dealing with this problem for quite some time now because i've been told its due to aftermarket cams and the overly sensitive knock sensor....

This started after i installed IPS-KT1's, 750cc injectors and Walbro using the GReddy turbo kit. I got it tuned by Evans-tuning.... I get the CEL flashing numerous times during light driving at low rpm. It most commonly happens when i go to take off or when cruising and my rpm's are below 3000 and i'm giving it very light throttle. If i give it gas, the flashing CEL goes off. It happens in all gears and has been really starting to piss me off. I just want to make sure i'm not hurting anything.

Again... only when applying light throttle and more so when rpm's are below 3000 and almost all the time when taking off. No knocks when at full throttle or after i give it more gas.

Thanks.

Have you had Evans look over any datalogs? I was told it is possible to accure knock counts due to chassis vibration thru the mounts and/or mechanical noise from the engine.
