backfire video
 

Guys my tuner just finished up my car and happily made 457 whp on a mustang dyno on 91 crap octain and 370 humid weather at 8 psi gtm stage 2 sc, and one of the maps is the u prev 2 step back fire map here is a simple video of what it can do will post more videos at recondition

It says Video is set to "Private" but nice gains OP :tup:

Ohh sorry will adjust that now

Link will work now guys

:eek:

Holy crap. I thought this was going to be one of those situations where someone was confusing back-off burble (gargle) with true backfiring.

I was wrong.

Very very wrong.

Had no clue uprev could do that

Wow!! I want that on my future setup:yum:

I had no clue as well until my tuner said that there is this option called uprev 2 step back fire, and it's a separate map all together

i want...

Amazing, quick question with your setup are you 7AT or MT??

I'm a 7 at with a gtm stage 4 tranny upgrade

Sweeeet! :0

did you get the transmission tables sorted out?

Dear sweet Jesus! That's sooooo bad@$$ I NEED to set this up on my Z when I get the tune lol

I can do that on a personal level if I come off my dietary restrictions.

Yes sir all sorted out car drives smooth now and shifts smooth like oem couldn't be happier thank u for bringing that to my attention before I blow a 4k transmisson:tiphat:

Er... you've tuned out most of the backfiring, right?

This map sir has nothing to do with the map that I drive on I have 3 maps currently high timing low timing and this map which is just for show purposes now I can drive on it but it's locked on 3k rpm it's juts a map for show where u rev the engine till 3k and heats up and emets the flames the explosion happens in the catback so no dang ours on the engine

You made 457whp on a Mustang Dyno:eek2:

Nice, might as well as replace one of the 3 maps with this. But it can't be good to do that often.

so this is not the same map = valet
valet map stops at 3k also

Valet map is whatever your tuner tunes it to. My stops a 2.5k since I can make boost below 3k rpms.

ok someone find me a tuner around here who can do this lol

Seb? :)

they can adjust it but would the effects be the same your bouncing off the rev limiter i.e fuel being dumped into you exhuast and spitting flames out the back

because with a true 2 step your not changing maps

just want to make sure i under stand this correctly because it sounds like the valet map being used to do this

i will test it with my car when i get a chance im set for 3k

i have my own uprev kit i wonder if i'm capable of putting a valet map on mine to do this....hmmmm lol

I am curious as well. I currently have the Valet mode which I sometimes turn on to have a "Rev-Limiter" but nothing that would emit flames!!! So sick!! :happydance:

MOAR VIDS!!! :stirthepot:

well i do have straight pipes soooooo i already shoot fire from time to time but if i could do it on command now that would be pretty fun lol

Valet mode plus retarded timing plus a **** ton of fuel

i will ask my tuner for exact details and dangers if any and how the process is done of course im not planning to do this on a regular bases but initially asked my tuner and he told me not much danger i just have to let the car cool down for about 20secs as the headers get over heated if not

Ah, ok -- wasn't sure if this was something planned and controlled vs. not.

It's still probably not great for the engine or sensors and definitely not for whatever muffler you have -- rich mix, high heat, massive carbon deposits, big pressure wave moving against the flow...
