UniSettings - Exhaust Pops On Overrun

Pyro

Guest
I'm running stage two lc with 3" blueflame DP and 2.5"decat + 2.5" superspint system and I get a few pops here and there on normal driving while shifting etc but if I floor it and then come off onto ovarun I get some really sexy pops bangs and spit flames :D

When it was really cold I was spitting 3-4" flames and poping like mad even driving slow :) I'm pretty sure this I caused by over fueling as my lamba is not mapped out for the decat etc and I have codes up ;) so I think it may work I haven't red page two so sorry if I'm being a parrot :p lol

Not to my knowlage :)

The car is over fueling due to lamber codes but that's from the decat ;) See the second post down on this page ;)

JamJay...... did you ever go any further with the unisettings? if so did it work?

It's booked in next week for a free flowing 3" system to be fitted so I'll run that in and see what I get. It might be that this is the key to what I'm after but if not then I'll play with UniSettings. I'll update this/my build thread with results.

That sounds like what I'm after but you're right, probably down to a little over fueling. How's you fuel economy ot of interest?

I can pops on hard gear changes, and when the traction control kicks in when it's switched on. Never really on the overrun though

I get a few of these now although very muffled by the OE cat-back, sounds quite comical at times.

Let us know how you get on. I know that WOT boxes give a nice pop on gear changes but I've never heard one on over run.

Video would be great :). There is a video on Youtube of an LCR racing a Mugen CTR and it lets out big flames on the over run, the member was on her but he got banned...I think. Anyway, I spoke to him before thise and he is running a non-res system with high flow rear silencer, no idea on the piping diameter but I would say 2.75"+. There is also another member here who cut his OE system, removed the mid-silencer and put it at the back where the rear box is after completely binning the MASSIVE OE rear box. In essence, a high flow 2.5" system.

I have a 3" decat mated to a 2.5" straight through system to a free flowing back box. Got it custom built at exhaust a fix in Darlington. It pops and bangs at almost every opportunity:D and its not remapped yet. It sounds especially good when the exhaust is hot and the t/c comes one, sounds like a drag car on overrun. How ever, it is just a little too loud for me for day to day driving, my friend took it for a spin whilst I stood at the side of the road. He pulled away full chat, it sounded awful, just a wall of noise. So I'm getting a custom middle box made just to take the edge off. I'll let you all know what it sounds like tomorrow after they fit it. :)

Thanks Edd, please do :)

I'm getting rid of the mid-silencer and will play around with the rear box. I'll try a free flow one first but if that's too loud I'll try the next one down. I don't want to baffle the rear box too much though or it'll defeat the purpose but i'm unsure of how a mid-box would effect things :shrug:

My fuel economy isn't to bad tbh I'm still doing a good 280-300 miles on 1 tank unless I'm abit bevy footed etc (witch I am :() iv text my mate today but he's in turkey lol so I dunno when I'll get a reply fingers crossed he still it :( As I'm nor sure what he does with his helmet cam vids I've also notice today that now I've put my catchtank back into the tip it's not as popy :think: I'm not sure how it's effected it or even if it has but on my way to work it didn't pop much could be coz I haven't driven it in 3 days tho :shrug:

Yeah, looking at the instructions it looks pretty straight forward. There is only 6 wires that need to be hooked up.

A guy on one of the vw forums has done a good fitting guide aswell so Ill print that off aswell.

I wonder what it would sound like with the WB fitted and unisettings altered.

Just tried that software linked on page two. But I can't get the fueling to stick. Sometimes it saves but when you rescan it's at default.

And sometimes it fails because it can't read the RAM.

Any ideas??
