JOEL Posted February 4, 2022 Report Share Posted February 4, 2022 Hi everyone, Quick question, when using "Gear Shift Control" for flat shifting, I'd like to confirm the meaning behind "Driven Up Shift Fuel Trim" The way I understand it by the word "Trim" is that this table will introduce a fuel cut? If I'm correct in that it is cutting fuel on the up shift, is there any way to add fuel during up shift?? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 4, 2022 Report Share Posted February 4, 2022 A trim is a small adjustment. Driven upshift fuel trim is a small adjustment to fuel during an upshift. If you put a value of 10% in that table then 10% extra fuel will be added during a gearshift, if you put -5% in there then 5% of the fuel will be removed during a shift. If using ignition cut then adding fuel during the shift can be used to reduce the backfire bang, reducing fuel can result in a crisper torque recovery but generally results in louder bangs.
