Rexer200 Posted October 22 Share Posted October 22 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? 3 Quote Link to comment Share on other sites More sharing options...

Kingster Posted October 22 Share Posted October 22 This was mine with Damian at Daytuner just before he (mostly) mapped it out. 2 Quote Link to comment Share on other sites More sharing options...
Terry Everall Posted October 22 Share Posted October 22 My 1548cc Busa used to do that and I just left it alone. Quote Link to comment Share on other sites More sharing options...
Tim-s Posted October 23 Share Posted October 23 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 Quote Link to comment Share on other sites More sharing options...

Rexer200 Posted October 24 Author Share Posted October 24 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 😀 1 Quote Link to comment Share on other sites More sharing options...
