Did IHE, do i retard timing now?

By 95c1v1c

I'm pretty sure it doesn't work like that

check all the lines going in/out the intake manifold

u just basically enlarged things. more exhaust will come out. so u will smell it more.. obviously. did u keep your factory catalytic converter or did u get the full ebay special with the "high" flow test pipe? if you did ur def going to smell more fumes than normal and FYI this is normal...

- Tue Mar 08, 2011 2:24 am #242842 Even if you did need to adjust timing, you wouldn't retard it. Retarding your timing would allow the piston to travel further up the cylinder before triggering the spark. This would increase the odds of detonation and/or pre-ignition.

If you needed to adjust your timing, you would need to advance the timing. This allows for an earlier ignition event, resulting in a somewhat higher combustion pressure by the time the piston reaches TDC compression stroke and starts it's downward travel in the power stroke as well as reducing the risk of damaging detonation and/or pre-ignition.

Adjusting the timing will not affect the fuel.

Keep the timing stock. Advancing the timing causes the flame front to peak as the piston is still traveling upwards. Thus it fights the piston on the way up reducing your engine's output. The only way to know is with a dyno.

Touching the O2 sensor doesn't hurt it.
