Why am I knocking? MS2E
This is my first car to tackle the tuning on my own. I've done tons of reading and research on here and other sites, bc I hate to clog up forums with useless stuff. But I've run into an issue that I can seem to figure out on my own.
I'm experiencing a semi random hard to pinpoint "knock" issue. For back story I've tried retarding the timing over 100kpa by as much as 4* and I still get knock retard for a short period. I'm going to attempt to attach my current .msq file, and a short log I took today on my way to work.
ECU: Reverant MS2E
Engine: rebuilt 1.8, 1mm oversized intake valves, forged rods, ceramic coated oe pistons, arp head studs
Turbo: FMII GT2560, cast log manifold, intercooled
Injectors: RX8 Yellow
Exhaust: 3" turbo outlet back, no cat
***I've only tuned up to 60-70% throttle input and ~8psi.***
