Im in need of help. I would like to know every component that would alter setting ignition timing.
Took my car in to a known shop and had it gone over but in the amount of time he had he couldn't find the root cause.
mechanical timing is set perfect
s13 harmonic balancer on s14 block (only difference between s13/14 crank pulley is ribs for ps pump) timing marks are the same. so no issue there
zero boost leak
plugs gapped @ 30
370 injectors oem fpr
enthalpy tuned ecu and he told me to run 15*btc of course
when timing is set @ 15*btc it bogs and backfires
but when its slightly advanced it revs happy and runs great.
to get it set @ 15*btc the CAS was clocked all the way right
it should be in the middle of the adjustment window im aware of so its right around the middle now and it runs fine .
what should i look into changing ? only thing we could think of is water temp sensor and CAS?
