1ft of fire coming out of my exhaust pipe!

[GSTdude06]

This problem just started a couple days ago but I just notice that fire was coming out tonight.

When im in second gear and on around 4k it makes a LOUD POP noise and fire shoots out while it pops it stops boosting but then once the pop is gone it boosts then pops again then I have to shift.

Ive only seen this problem in second cause once I noticed it I stopped driving it WOT


Could my air/fuel mixture be wrong? To much fuel not enough air so Im getting gas in my tail pipe that explodes?

Help Please!

 

[allwheelTSI]

Yeah, that could be the problem, it would help if you could give us some specs.

 

[GSTdude06]

Like what I have done to the car? sorry Im not that great at this.

 

[MrBoxx]

Are you venting or recirculating your BOV?

 

[allwheelTSI]

Yeah, whats done to the car, what are you tuning with?

 

[GSTdude06]

it venting.

I have a SAFC but its all default settings


This weekend im changing my injector o-rings cause im leaking air out of the middle 2.
And I have to set my FPR for around 43 or 44psi (thats correct setting right)

 

[allwheelTSI]

Yeah, you should'nt be venting, thats probably the cause, or atleast part, and i think the fuel pressure is supposed to be 43.5, so yeah..

Do you have a MAFT setup to safely vent? if not you should put the recirc. tube back on.

[MrBoxx]

Unless you have a MAFt, put your recirc tube back on. And don't take it off till you do have MAFt.

 

[GSTdude06]

What is a MAFT? Where can I get it? And why do I need one?

Ive never heard of it. Sorry.

 

[allwheelTSI]

It allows you to place your MAF sensor (a GM replacement) inbetween the BOV and throttle body so you can vent without running rich, and it also allows you to adjust air/fuel mixture.

[GSTdude06]

I have hard UICP, ill have to cut the pipe? Then place that in between the TB and the BOV?


Thanks for the help yall!!

 

[dsmsucks]

Yeah you can simply hack your current pipe or wast money on a dejon tool one!
You can put the gm maf between the bov and throttle body to vent or you can put it before the turbocharger!

 

[DSMcrazy3]

or you can put it before the turbocharger!

The pipes start after the turbo..

 

[MrBoxx]

Yeah, but theoretically the MAF can be run in a "suck-through" method instead of "blow-through." I think it would be more accurate as close to the throttle body as you can get it, which is why so many people put it within a few inches of the TB anyway.

The pipes start after the turbo..

im confused too. i believe he was trying to say on the intake pipe. it is better to have it between the bov and tb, so it can read the adjustments from the venting.

Yeah guys sorry, I meant after the intake pipe

"suck-through"

I believe it's usually called "draw through."

But "suck-through" allows us to giggle like school children.

 

[mavisky]

If it's popping while you're accelerating then it's your tune. The bov doesn't matter. Right now it's probably running too rich and your plugs are probably fouled out as well.

 

[asian1]

Diehard F&F fans would love to have your problem J/k hope you get your problem solved.

 

[GSTdude06]

I just changed my plugs and wires last weekend.

I just put the tube back on but I havnt drove it yet so ill post the results.

 

[dave99gst]

o!, feet of flames!

You know you drive a DSM when you can look in your rear view mirror and yell, "That one blew a flame!"
