i've been whoring the search tool on this forum and i still cant work out an answer.
very rarely the engine check light will come on, and when it does the knock sensor on the pfc reads pretty high. last night drove the car on a cruise for like 2.5hrs and knock sensor read 126 once. @ 4600rpm
during the night only saw it ever got to 40 @ one stage.
thing is i havent hear the engine ping inside the cabin.
some of the boys reckon i was shooting flames last night but thats just fuel dumping right when changing gears?
the car tuned @ racepace last year, and recently was retune there last month. b4 and after its pretty much the same, knock goes off rarely.
mods are TB 3" high flow cat, pod, cooler, 12psi, pfc and walbro fuelpump which is only 3 weeks old.
i'm thinking to get some splitfire coils, anyone got any thoughts?
