SRT decel Gargle?

OhNoA2.0 · Post by **OhNoA2.0** » Tue Apr 09, 2013 9:24 am

Odd question, but what exactly is it that makes the the SRT rumble/gargle on Decel the way it does? I'm wondering if it's in the tuning. If so, what would I have to do on MS to make my boosted 02 R/T do the same? Right now it's very smooth on Decel.

It has no mufflers. Mine does the same gargling when I let the engine do the braking (cause I have no muffler or rear section lol). And I definitely am not boosted, let alone have any significant mods.

I have 3" straight pipe, it doesn't gargle like the SRT.

Lol the srt4 gargle is because mopar leaves the injectors open.on decel... where a regular neons shut them off

Is there any way to change that on MS?

Regular neons only shut them off on a hard decel. Light decel, they are still pushing fuel.

Some of it also has to do with how much the IAC is open during decel. If it is open more than others, the decel will be smoother. They did that more on carbureted engines with a solenoid to hold the throttle open, so it wouldn't suck as much fuel on high vacuum deceleration. About the only pupose it serves in injected cars is a smoother transition.

I bet if you blocked the IAC hole, you would see exactly what I mean. Or you could just unplug it, but you would get a CEL. Zero valve overlap also contributes to less popping and cackling, because you have less unburned fuel and less oxygen to make it ignite. A small leak after the cat (where applicable) will get you some more rumble on decel too.

My Stage 1 accentuates the sound but I really lust for the Stage 2 or Stage 3 noises. **sigh**

My Hemi truck did it, straight pipes and a very aggressive cam didn't help the matters much.

yes, i don't remember how erick had me do it though. shoot him a PM. it's some setting about turning on or off the injectors at a certain vacuum level

It's overrun fuel cut. Turn it off, and you may need to add a little fuel in the VE bins affected. Don't go nuts though or you will just foul plugs. Let me know if you need help.

Overrun fuel cut was already turned off.

This is something I specialize in. I'm uploading a video

Those sound violent! Like a decel 2step. My 03 always popped since I bought it with a straight exhaust to an OBX muffler. They called it bees fightin wasps in a can so I thought it was a neon trademark kinda. Since most others dnt like the sound as much.
