Phantom knock on my SR20!?
i experianced alot of phantom knock with my 1g dsm when i first bought it. but with much searching for a rattle and playing with the amount of torque on a brand new knock sensor i finally got it to go away. i also used my DSM link so it would not read knock below "xxxx" Rpm's and xx% TPS.
After driving the new car around (s14 w/ sr20det stock turbo stock boost, plenty of bolt-ons) every so often i get phantom knock below 3000 rpm. i know its not real because it only happens between 50%-75% throttle. it pulls my timing like crazy and i get full spool at about 1600rpm. my car sounds like im flying but feels like the hands of god are holding me back. its clearly igniting AFTER TDC. it happens some times when i get on it real quick to, it will spool real fast, be bogging down, then the phantom knock goes away, timing come back, all of a sudden the engine tone changes and im off. it sounds almost like it has Vtec its so bad.
im new to the SR20 scene and just was wondering if anyone else had similar problems.
im looking into getting some form of engine managment soon and hope that theres a feature on it to play with the knock sensor but i decided what i want to go with. possibly greddy E-manage ultimate? maybe AEM???
any help would be greatly appritiated cuz Im going crazy.
DAMN YOU YOU KNOCKING PHANTOM!
