Flames

[Rexer200]

I have a Mega S2000 with stock engine with Omex 600 ECU and no cat but stock silencer mapped by Northampton Motorsport in 2021 (although only 2000 miles ago). See attached dyno plot with air fuels.

On the track when the car is hot on a trailing throttle but still in VTEC revs then getting back on the throttle I get big flames of unburnt fuel out of the exhaust.

 

Any thought son this?

I'd put a call into NMS, this should be mapped out really

Yeah Troy will most likely know best what to do

This was mine with Damian at Daytuner just before he (mostly) mapped it out.

My 1548cc Busa used to do that and I just left it alone.

A lot of cars do it especially when exhaust temps are high 

un burnt fuel igniting in the hot exhaust 

think I’d rarther have that then lean

Yes - that front number plate screams “pull me over and write me a ticket”.  Be careful out there.

Thanks for all your feedback, what I'm hearing is that it's not generally considered to be harmful to the engine, which is reassuring..

 

@Captain Colonial Photo was taken on the track ! Anyway hopefully flames would distract the police from looking at the number plate 😀

Go to say it's a very good picture with that flamage

Agree - the Javelin photographer always likes  a good flame-out shot 😁

 

 

(this was after the big flames in the video above were mapped out!)

 

ooh found another 😎
