hey 'vrybody
i have a phenomenon in my car: s13 200sx with zenki s14 SR, s15 injectors, z32 maf, 2871r, powerfc.
sometimes when the VTC switches (at 5000rpm) the power fc registers a BIG knock. maybe 40- maybe 80 maybe 120+ :eek3:
i know it's the vtc's fault, cause it always appears at the switch point, and when i move the switch point around, it appears there too.
the thing is, its not a phantom knock it seems, it's real cause if i lower the ignition advance, it doesnt happen. but the car is a dog with that much less ignition...
does anybody else experience this? one other guy has told me it happened to him, and he removed the vtc, installed cams and never had knocks again.
so i have two options.either go without vtc or try going water methanol, to prevent knocks altogether.
...or both. opinions? ideas?
