jamesmark Posted January 15, 2008 Share Posted January 15, 2008 Fuel cut is a nasty feeling, he will get boost spikes and his turbos will pop eventually. Quote Link to comment Share on other sites More sharing options...

You must have one or an after market ECU, either that or your boost guage is reading 1.3 bar and you actually acheive below the 1 bar fuel cut limit on the stock ECU. I think you have to be over the 1 bar limit for a couple of seconds before fuel cut kicks in. Quote Link to comment Share on other sites More sharing options...
jamesmark Posted January 15, 2008 Share Posted January 15, 2008 backfire ??? Not really, fuel cut is exactly what it sounds like, it cuts fuel. So imagine your engine trying to work with no fuel going to it. Quote Link to comment Share on other sites More sharing options...

Soaruss Posted January 15, 2008 Share Posted January 15, 2008 I remember hitting fuel cut in my MR2 turbo in the fast lane on the motorway before i fit an FCD. It was scarey because i'd never experienced it before. Quote Link to comment Share on other sites More sharing options...

Ric Posted January 15, 2008 Share Posted January 15, 2008 3 seconds at 1bar positive pressure to acheive fuel cut Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted January 16, 2008 Share Posted January 16, 2008 3 seconds at 1bar positive pressure to acheive fuel cut Which will feel just like slipping your foot of the throttle at WOT and full boost. BANG! Quite uncomfortable. Quote Link to comment Share on other sites More sharing options...

Homer Posted June 11, 2008 Share Posted June 11, 2008 Does the Warning light and engine lamp com on when you hit fuel cut? Yes, as well as a massive thump in the back and a "WTF was that" moment.

SilverSoop Posted June 11, 2008 Share Posted June 11, 2008 I think i hit fuel cut today when i was going home from work... I shifted into 3rd gear, and overtook some slow coach going onto the dual carriageway and...i got thrown forwards in my seat with the traction control light flashing at me... Was this fuel cut or was it just traction control cutting power to the rear wheels?? Quote Link to comment Share on other sites More sharing options...
