wasted talent Posted May 12, 2019 Report Share Posted May 12, 2019 (edited) Hi all, V1/2 g4+ plugin ecu, 05 wrx knock sensor in standard location, ej257 with v3 heads. Engine only has 1500km on it. I'm constantly seeing knock from idle to redline regardless of load or timing. only way to get a zero knock reading at idle and any rpm is to turn off cyl 1 sensing while leaving 2, 3 and 4 active. what can cause this to occur? will upload a pcl file later today edit: attached most recent .pcl i have access to currently. all knock settings should still be the same iirc current 2-4.pclr Edited May 13, 2019 by wasted talent added .pcl Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 13, 2019 Report Share Posted May 13, 2019 The gain channel is set much higher than I normally see, more typically it is 1 or 2. Usually I would set this so you have an average knock level of about 100 reported at medium speed/load. I would also set the start window higher - about 15deg. Not releavant yet but will be when tuning: Your target table needs the Y axis changed to "MAP", it is currently set to "AN1 - MAP Sensor" which is raw voltage rather than pressure. Clear I-trim tables should be set to ECU power on. Quote Link to comment Share on other sites More sharing options...
