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 |

QUOTE (Syaoran @ Mar 29, 2014 - 11:48 AM)  Try stepping on it after 3000rpm instead of at lower RPM. Sounds like an issue some newer turbo cars have where they knock down low because they make too much torque at low RPM. Its all part of how the timing map is setup for that range. Its not normal and shouldn't happen. This is also a very common area to hit if just daily driving up a hill. -------------------- 15PSI - 30MPG - Megasquirt Tuned
