Hi, this is my first post here so I apologize if this isn't the correct section for this.

I just received my Tactrix 2.0 and did my first log ever and I noticed some FLKC. If someone could take a look at this log and tell me if this amount of FLKC is normal it'd be greatly appreciated.

The car is a MY03 WRX USDM and the only mod is a catback exhaust. It is running a stock tune. I logged a 3rd gear pull from ~2500-6000 RPM and noticed -1.05* of FLKC between 2500-2600 RPM and 3550-4200 RPM. I know a small amount is normal, but is this much still okay?

Here's the log for those interested: https://docs.google.com/spreadsheets/d/11O0i7LOm8gea38lfX2HQPa1oxG0PxSw-jyG3ShlyYl8/edit?usp=sharing

Thanks

not enough to make a huge fuss over, but me being me I'd probably still try to diagnose why

at least the function of the knock system is working

it could be any number of simple things, as the knock detection system is rather sensitive. knowing that the minimum retard value for fine learned knock correction is -1.05 degrees, at least it isn't showing a lot of fluctuation or has it everywhere with a low IAM to boot.

have you discovered learning table values? learning view? this will show you the fine learned knock, as it appears, in table form. along with a,b,c and d learned fuel trims, misc. ecu/rom identifiers and any diagnostic trouble codes.
