Crispin Posted June 29, 2015 Report Share Posted June 29, 2015 Some questions about the gear cut settings. Is there no way of cutting the ignition 100%? I have a very quick sequential gearbox with paddle shifting so I need the rpms to drop as quickly as possible. How is the fuel applied during the cut cycle? Is it enrichement on the calculated pulsewidth at the time when the ignition cut is removed (e.g. when ignition is back on to normal) I'm running G4+ Xtreme latest firmware (5.4.3) Quote Link to comment Share on other sites More sharing options...
Simon Posted June 29, 2015 Report Share Posted June 29, 2015 Hi Crispin Yes you can set the Driven Up Shift or Down shift cut to 100% if you wish. The Fuel if a % increase on the calculated fuel while the cut is active. Quote Link to comment Share on other sites More sharing options...
Crispin Posted June 29, 2015 Author Report Share Posted June 29, 2015 Hi, if the driven shift cut is set to 100% and and ignition trim to -15, what is the end result? Not sure I follow how the trim and cut tables work together. While the cut is active, how is the fuel trim used? I assume I will run rich during the cut so I thought the fuel trim table was used for reduction of fuel? But it's only positive values in the tables hence my confusion.

Simon Posted June 29, 2015 Report Share Posted June 29, 2015 The ignition trim will have no effect as with 100% cut you will have no ignition to retard. The enrichment is geared to have some extra fuel when the load comes on. I would not expect it to need to add much fuel if any at all.

Crispin Posted June 30, 2015 Author Report Share Posted June 30, 2015 Thanks. I'm expecting the gearbox to shift in 50-70 ms so I will start with 100% cut and no extra fuel given the quick shifting. Quote Link to comment Share on other sites More sharing options...
