mario_82_ZXT Posted May 10, 2005 Share Posted May 10, 2005 What are your settings for this? Mine are set at this: RPMs higher then: 1900 KPa lower then: 25 TPS lower then: 42 Seconds: 1 I ask because the factory ECU has a more complicated fuel cut off system: Thanks, Mario Quote Link to comment Share on other sites More sharing options...
Guest Loose_Screws Posted May 10, 2005 Share Posted May 10, 2005 Mario, I never realized what this was! I was thinking 'over-run fuel cut' was when the engine was running away or something (held over thoughts from Detroit Diesels). I will have to experiment with this and see. Fuel vapors fill the cabin on decel pretty badly and this would help eliminate that. Give me a couple of days to test and I'll respond.

Tony D Posted May 11, 2005 Share Posted May 11, 2005 mario, that is an anti-backfire and fuel economy measure. You have settings basically approximating the last scenario, which is the only one you really needed to worry about. The other two are anti-HC spiking control algorithms to lower emissions. If you aren't really coasting much or heavily decelerating constantly it will make little difference. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted May 11, 2005 Author Share Posted May 11, 2005 Trying to squeeze out a few more miles per gallon. Plus, I love engine breaking, so I bet it will see this quite a bit. Now to get rid of that stumble... Thanks, Mario Quote Link to comment Share on other sites More sharing options...
