Default Re: Buildjournal Exhaust Backfire Tune

I am posting this in here instead of the tool thread to not clog it up but I have a SMG and have been able to get the car to shoot flames while sitting still in traffic. The stage 3 does consume a lot more gas however for those that didn't already know.

exhaust setup is AP headers -> OEM section 1 & 2 -> gutted OEM section 3, i do have an exhaust cutout in the section 2 as well

I also have some other stuff as well and TTFS tuned my car for the csl airbox, so that may also play a factor but rev up to about 7k rpm and tap on the throttle. I had to do it with sport mode off though, if I have sport mode on its not as aggressive i noticed.

I believe its due to the airbox, i tried with sport mode on and off, same result.
U revved it up to 7k in N ? i think thats a bad idea for your rod bearings

The flame tune would be successful if it throws flames when you downshift, if it's meant for revving in N then it would cause more harms than goods.
About the gas, actually i felt the same.
Try clearing your adaptations before reflashing your old tune

It should keep your existing tune if its not encrypted or locked by your tuner.
The mapping just deals with the overrun conditions

I have oem headers with cats and a top speed exhaust and I managed to get a little flash with the aggressive map. I got it when coasting down from high rpm's and tapping the gas around 6000rpms. It wasn't anything crazy enough for my friend to notice driving behind me. However my new headers came in today and I can't wait to try it out then.

not seen a change in burble from the previous version (SMG)

Going back stock, however it's been fun over the years having burble before Lambo/new gen cars started having it.
