Less air when cluth is depressed

[smslyguy]

Which parameter controls the amount of air exactly when the clutch is depressed? I was thinking it was b4309, but i beleive it to be a decay rate.. Not quite sure though. my car revs slightly higher when the clutch is disengaged. Was woundering which paramater controls this?

If your foots off the accerator completely when you press the clutch in, then its the throttle cracker P/Neutral. Timing also affects idle stability or instability during this coasting phase so have a look at that too and see what its doing. Any questions or logs/tune file just post. > Mike.

Thanks for the reply... My throttle cracker p/neutral is zero'd out completely.. Meaning there is no air added to that chart.. What does b4313 (throttle cracker decay rate) exactly due? Is that not a "delay" before it actually pulls back on the throttle??

A "Decay Rate" implies how fast the setting is reduced by. It's not a "delay" as such, in this case it'd be how fast the cracker setting is returned "0". A "delay" setting would imply a period of time before the cracker started to be decayed back to "0".

So....

{B4314}: sets how long the cracker settings are held for before being returned to "0"
{B4313}: sets how long it takes to ramp the cracker settings back to "0"

Subtle difference, but important to get right.
