Pops and Gurgles via ATR

I have ATR and am considering adding a little "pop and gurgle" to my tune. I've narrowed down these tables as the most likely ones to modify for this effect since I can hear slight popping during warmup under deceleration.



Those of you who have added this feature yourselves, are there any values in the "Warmup (Transient Fuel): Transient Fuel Time Constant Warmup (Decel)" table's lower right that you had good results with?

I'm guessing something around 4 seconds should be sufficient.

How about "Warmup (Transient Fuel): Transient Fuel Gain Warmup (Decel)"?



I'm thinking around 0.18 between 150-200F and 130-250S.

Lastly "Transient Fuel: Transient Fuel Gain (Decel)" could be richened at low MAP and between 3000-4500... but not sure how much.



Thoughts?

This just in, Adam Brunson says I'm way off and that he doesn't even touch these tables to achieve his result. Argh!

Another follow-up. Adam says the tables required to achieve this aren't offered in ATR.

Guess that's the end of it.

I wish we could get our hands on ATR, I just want to be able to mess with traction control and launch control settings. Kind of lame that they removed it...

The last thing I want to have to do is go to a tuner or pay for a custom tune just to fiddle with the settings.

They still have launch control fuel and throttle in it. But we never got ign based traction control :(

Sucks we can't get ATR, I self tune my Evo and enjoy it. The way we would get crackles and fireballs on the Evo is to reduce timing and add fuel in the low load parts of each table where the ECU would read when you let off. I'm new to the AP so I'm not sure how the tables look on that but here's an example of Evos with crackles.
