Now how would I get my car to do this?

Is it a case of having a mappable ECU and creating a longer fuel overrun?

Or can it be done with a stock(ish) setup engine with an exhaust upgrade?

The car in the picture is Mr Whiffin's is it not, and the spec is... well pretty damn high.

My existing setup will pop and bang every so often and I may get a small hint of a flame once in a while, but I'm not getting any flames of that size.

You just can't beat a car that fires flames in anger like that, its very impressive. May not give a faster lap time but it sure looks good whilst you're trying.

(not wanting to go down the chav-flamer-kit route by the way)

That RX7 I went to Wales with spat flames the size of umbrellas- I'd love to do that!

I think I remember reading a thread where CW said about retarding the ecu to overfuel like crazy too shoot flames like this, may come up on a search?

Lots of overfuelling probably?

I have a full decat and when I put in a walbro fuel pump it became a flame-thrower . Unfortunately, when I put in the restrictor ring this went away

overfuel and retard ignition at higher RPM range a tad.

is that safe for the engine Thorin?

And this won't be possible on a stock ECU I take it... unless you piggy-back it with anither chip.

I believe TAZ is an expert at doing this

Its just a case of flooding the exhaust with unspent fuel by revving on some decent injectors with either bad or extreme timing.

doods little switch on the dash and a spark plug in the outlet pipe on the rear can !!!! lol

I used to have a flamer on my last car. Its a simple as overfuelling with a live spark plug in the exhaust and you can see amazing results. I saw one Evo spitting 10 foot fireballs as below......

the plug in the exhausts is for chavs and its cheating

lol, didnt spot that!

its like a lego car

lol double post

In rally cars, the flames from exhaust gases are generated from a technical peice of machinery which keeps the turbos spooling when you take your foot of the gas so the boost is still there when you plant your foot back down. They say that its kills turbos like nothing else tho so they dont use them on normal cars where you would want your turbos lasting more than a couple of races!

LOL you mean antilag, where you effectively let fuel into the exhaust to keep the turbo spinning. Yes the exhaust wheels dont like it ( rally cars use iconel wheels AFAIK)

There are ways of setting certain standalone ECU's up to give large flames on lift off.

I had some excellent flames out of the exhaust and trumpets when playing with the ignition and webbers on the kit.

would you not get a little flame on high rpm change up wth a de cat???

or nothing........ ?

That's not a wing - that's a bloody trellis, that is!

The ECU completely cuts fuel when decelerating above a certain rpm. If you have an aftermarket ECU and don't enable this deceleration fuel cut off (DeFCO) then you'll get flames. As has been mentioned before, the turbo won't like it much, and on other cars that have ceramic CAT's you can feck those up too.

Essentially, in my book, it points to a poorly mapped car.

And that rear wing is obscene.

The Carling F3 race team used to set up both of their F3 cars in the BritF3 Championship to overfuel on lift-off.... I asked one of their engineers a while back why they did this and he told me that it gave quicker throttle response when the driver came back on the power.

Don't know if this is applied to all types of engine mapped this way, but it seemed to work for F3 cars as Carling won the season that year with Takuma Sato.

As Tony already stated most stock ECUs will use some form of DFCO, I have this turned off on my AEM to get the flames, bangs and pops.

Is it a simple and reversable process to turn off the DFCO on a stock UK-spec ECU ?

Since the stock unit is non mappable i guess you cannot turn it off, maybe some of the rechipped units like the Blitz and Mines have it disabled but thats only a guess.

mine does it, all the time or when i want it to. its really simple too. as long as you have no CATS, get a flamer kit fitted. thats all most of these are, no fancy stuff. just a coil in the boot and a plug about 3 inches from the tail pipe.
