Is there a clutch delay valve in MR?

Which Tial BOV did you go with? are you running VTA or recirculated?

If you're registering knock counts, your ECU is pulling timing. Plain and simple. Knock count = amount of knock after taking into account the knock filters configured in the ECU.

HKS Super SQV (Super Sequential Blow Off Valve) will harm something?

went from the 50mm blow off valve to the alpha q for better driveability

bringing this back, im getting knock counts when i shift almost every gear everytime. my setup and tune is similar to OP. i have stock motor mounts, but possibly could just need a new knock sensor. has anyone played around with the knock sensitivity in ecuflash to reduce or get rid of this? its over 6 counts right after shift before steppingon the throttle again. im on speed density 2.0 with tephra v7

Hey, fellow Ontarian here! Do you have a log to show where it's happening? Do you lift hard off the throttle between shifts? Do you feel it happening or just see it on your display/logs?

I got a sequence of knock sums from 11-1 yesterday in my MR in the span of 1 second real time, lifting off of a 3rd gear pull, decreasing load. I worried a bit until I saw the log. It was a violent decel until a selected 4th and let it wind down slowly.
