R24 Posted February 9, 2022 Report Share Posted February 9, 2022 Hi All, Can anyone share how can I create a 4D table with IAT ignition trim and timer to solve my hot start lean conditions? Ive tried to relocate the sensor from intake the throttle body where the sensor now sits on the silicone hose joint but still have the same issue. Would like someone to have done the 4D setup successfully to share their knowledge here. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 9, 2022 Report Share Posted February 9, 2022 This is how I would do it. Put Engine running time on the Y axis of your IAT trim table. Start up will be the top row, normal running will be the bottom row. This is just a rough example but in this example if IAT was 60deg or above at start up it would pull 20% fuel out for the first 10seconds of running and fade back to normal fuel after 30seconds.

Adamw Posted February 9, 2022 Report Share Posted February 9, 2022 Oh it should have been adding fuel in the top row for your issue too, must have been dreaming when I done that table. Quote Link to comment Share on other sites More sharing options...
