boostDR Posted October 23, 2017 Report Share Posted October 23, 2017 Hi all, I have a distinct lag between my knock threshold Log and my knock target table trace. First thought was the ECU was running a different map when the log was completed however this isn't the case. Anyone else having the same issue?

mapper Posted October 23, 2017 Report Share Posted October 23, 2017 check at what rate the knock treshold is logged. Try at least 25hz or more. Think a slow longging rate could be your problem boostDR 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 24, 2017 Report Share Posted October 24, 2017 I think we would need to see the log and map to work out the cause here. Quote Link to comment Share on other sites More sharing options...
boostDR Posted November 4, 2017 Author Report Share Posted November 4, 2017 Was logged at 25Hz. Changed to 40Hz and it now looks as it should, thanks Mapper mapper 1 Quote Link to comment Share on other sites More sharing options...
