With that said, I however can not be held responsible for anything that could or may happen to you and or your vehicle by using any files that i send you :iono:

Haha!
I'll trying messing with the stage 2 UEL tune and well see what's up.

What did you put the overrun RPM delta at? did you change any other overrun parameters?

overrun RPM delta to 6000ms and what I stated before was all i changed.

Overrun enrich delta is a time period after you're off throttle in ms, not rpm.

i'm about to try it now (finally was able to install it)
just want to make sure, is it normal that it says a error message first when you open file (error about checksum) and then when you upload it to OFT it says Checksum corrected?

Yup.

with just ignition base timing A modified, no pops produced. ignition base timing B produced some pops, but not as aggressive. i ended changing both ignition base timing maps A and B to -10* timing in the lowest load column(.15g/rev) for the most aggressiveness. with the lowest load at negative timing, it kind of made the throttle an on/off switch for the pops. you wouldn't reach that engine load when normally driving or when decelerating. but if you gave it the slightest bit of throttle to that sweet spot, it would spit pops and become obnoxious. but everyone loves it. changing the full decel engine load value to negative timing doesn't produce pops for some reason. but its better to not have pops at full decel because you don't want to constantly become a pack of firecrackers when coming to a stop.

after messing with the ignition maps, i started looking into fueling. with the overrun enrich rpm delta activation set to 6000, the pops were alot more aggressive and rally sounding, as opposed to before where it sounded like you were running over a bunch of pop cans.

trying to achieve flames but i think this is as far as im going. i don't want to break stuff

Can't say I've ever heard a can of shit make noise like that, but I'll take your word for it. :lol:

I'll try to get some clips of mine with my adjustments, it's subtle.

enrich delta is oem on wrxs at -17. a positive number makes in inactive i believe. when its on engine braking is much harder.

I'm hoping it sounds better in real life. Plus, messing with my file and changing stuff like this is fun. :)

I love tinkering with shit, even shit cans.

That makes sense if it is measured in rpms and not ms. It's related to how often the fuel injectors are going into overrun mode as the engine drops in rpms.
