ryota Posted December 17, 2023 Report Share Posted December 17, 2023 I'm trying to apply gear shift (flat shifting) on Evo8. It turns out there is injector spike during gear shift like attached photo (yellow) Could you tell me how does it come from? 20231217 TC2000 1本目用.pclr Quote Link to comment Share on other sites More sharing options...

ryota Posted December 17, 2023 Author Report Share Posted December 17, 2023 Thank you for the reply. In case I reduce 25% fuel, do I need to input “-25” in that column? Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 17, 2023 Report Share Posted December 17, 2023 Yes, -25 would reduce injector PW by 25%. That would typically not be recommended however, this means you will have some very lean combustion events at full load/full boost. Most commonly you use 0% fuel trim or sometimes add fuel +10 to +20% can be used to reduce backfire severity. ryota 1 Quote Link to comment Share on other sites More sharing options...
