Tim D Posted January 5, 2019 Report Share Posted January 5, 2019 Hi... Please could someone advise on a Det query on Impreza STI? I spent a lot of time setting up knock control (frequency analysis, det cans, inducing controlled knock etc...) and got a really responsive setup and running completely knock free. This was in the summer months when it was 20 degrees C. Now it's colder (freezing), on occasion, the system detects a single knock event around maximum torque (5500 rpm, 240 kpa, see attached). Would you use the IAT Ign Trim table to resolve this? It's currently set to remove timing at high IAT only (see attached). Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 6, 2019 Report Share Posted January 6, 2019 What was the IAT in that region (5500 & 240kpa) in winter compared to summer? Quote Link to comment Share on other sites More sharing options...
Tim D Posted January 6, 2019 Author Report Share Posted January 6, 2019 Hi Adam, IAT in that region was around: 10 C winter 35 to 40 C summer Quote Link to comment Share on other sites More sharing options...
