Davidv Posted September 2, 2017 Report Share Posted September 2, 2017 Hey, Lately I have been experimenting with having closed loop lambda turned on under all conditions.From recent experiences having seen Motec M1 ECUs do this effectively I thought I'd give it a go. And it works well, even at WOT and high RPM.However it would be nice to be able to set a finer level of control over how much it can add or remove. For example under cruising conditions I might be completely happy for the ECU to add or remove 40% fuel.But at WOT, it would be nice if I could specify only say 10% change and enrichment only so it's never going to run leaner than the tune specifies. So if there is a sensor fault, it's not going to nuke the engine. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted September 2, 2017 Report Share Posted September 2, 2017 I wouldn't be happy with the tunner if the ECU had to add or remove 40% fuel. Any more than 5% either way I would be looking into fixing the map. Quote Link to comment Share on other sites More sharing options...
Davidv Posted September 3, 2017 Author Report Share Posted September 3, 2017 I mention 40% as that's the current allowable maximum. The main thing that would be nice would be able to specify seperate percentages for adding or removing fuel. Quote Link to comment Share on other sites More sharing options...
