Gas Pedal Delay

juld0zer · 05-17-2014, 08:05 PM

aside from the obvious causes (intake air temp, coolant temp and oil temps), what else could be causing this throttle lag???

I've pretty much eliminated IAT as the cause.

I'm now leaning towards the EGR system which involves the CVTC system. EGR is intended to reduce emissions by reducing combustion temperatures....by filling part of the cylinders with exhaust gas to effectively reduce the available volume for oxygen to enter/fill the cylinder.

This is no easy fit-a-blank experiment and will need someone with tuning experience to chime in... i've got an Uprev tuner license so if someone can guide me, i am happy to guinea pig my car for the benefit of everyone as we try to solve this mystery once and for all.
