Guys just need some guidence in "how" to tune out shift knock. What i'm finding is that under full load and when shifting I can hear the car knock for a split second. I have logged the knocks but it is only during shifts and not everytime.

Any suggestions on how to remedy this?

HKS ST @ 7PSI

 

im not real familiar with the haltec em..... but in tuning my utec i have found that setting the timing values above 5000 rpm in zero load to the identical timing values above 5000 rpms in 70% load and up, it got rid of my shift knock.

keeps a radical change in timing from happening when i lift to shift, which what was causing the knock.

hopes this helps, good luck

 

Yeah thanks for that. i noticed that in another thread. I Will need to pass this on to my tuner to see what his thoughts are.

thx again
