I am in need for some expert advice. Currently I purchased a used PowerFC for my ST205 and brought my car into a shop for a safe tune (not aggressive). My issue is my Check engine light flickers on and off, I noticed that knock starts to report at low RPM range. 2600RPM - 3000RPM. I dont hear any knock and Im hoping that its phantom knock. I have added my logs from datalogit f anyone can provide any advice it would be appreciated.
my current mods are basic: HKS Intake Exhaust manual boost controller set at only 15-16 lbs. and Berk Downpipe. HighKnockLogs |

Just got back from the tuner and it looks like the timing needed to be pulled back in a couple of cells mostly in n06-n08 range (low RPM range on the powerfc datalogit). We ended up road tuning as they said it was not necessary to put it back on the dyno based on the logs that Ive captured. The tuner sat in the passenger side with my laptop watching the datalogit/logs while I was driving to replicate the issue. Now my knock went from high 80s-90s to low 40's and below. NO MORE CHECK ENGINE LIGHTS!!! WHOO HOO!!! Was done all within an hour... I love driving my car again!!!!
