essb00 Posted July 27, 2023 Report Share Posted July 27, 2023 It should be easier to interchange the terminal connectors on the pickup sensor side. Properly wired Trig 1 & 2 should look like this below (compare the difference of Trig1 after the missing tooth going positive, and Trig2 where it should go positive before inverting to negative. castillaricardo, Andrew 1.8t and koracing 2 1 Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 13, 2023 Report Share Posted August 13, 2023 If you give us a log showing the problem occurring and a copy of the tune then we might be able to help, otherwise the best I can do is consult the magic 8 ball at work tomorrow. essb00, Confused and dx4picco 3 Quote Link to comment Share on other sites More sharing options...
koracing Posted August 14, 2023 Report Share Posted August 14, 2023 Lots of ways to have the knock settings wrong so they adversely affect idle. Hard to pin it down without the tune and a log as @Adamw stated. Quote Link to comment Share on other sites More sharing options...
