Aqmar Posted June 24, 2023 Report Share Posted June 24, 2023 Hi, Appreciate the guidance here. I have got my car running smoothly with the Traditional Fuel Mode. However, I want to utilize the various sensor I have installed to support the Fuel Equation Mode. I want to have my car run at a better precision, as that is what I understand the Fuel Equation Mode could offer. When I set up my Fuel Equation Mode, the 2GR engine got no problem to starts when it was at operating temperature (above 80°C). However, when I tried to start the engine below the operating temperature (30°C - 70°C), it just couldn't start. The engine can crank, but it doesn't kick to run the engine. I don't think this is due to Trigger Offset or the timing. I have tried to adjust the Pre Crank Prime or the Pre Crank Enrichment, but it wouldn't do.. What am I missing here? I didn't make much changes to my ignition timing as I understand the Fuel Mode only effects the fuel delivery. Sorry if this matter has been discussed before; I have tried looking into the forum but couldn't find about this topic. Below is the link to access the file. There are 2 base maps for comparison. (Traditional vs Modelled) and the Log File so we can have a better analysis of what really the problems are. https://drive.google.com/drive/folders/1xbpB16a7xE8XYHNd9Q8Z4CFu41Ow-TaO?usp=sharing Quote Link to comment Share on other sites More sharing options...
ellisd1984 Posted June 24, 2023 Report Share Posted June 24, 2023 I think it's a full returned of the fuel tables. I went from one to the other when I upgraded injectors to save having to tune the fuel twice Quote Link to comment Share on other sites More sharing options...

Are you referring to the Fuel System type? For my setup, I rely on my Fuel Pressure Sensor. The engine can start and run at operating temperature but not when it is cold Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 24, 2023 Report Share Posted June 24, 2023 It is nothing to do with fuel or cold start enrichment. You have a 100% ignition cut because you have enabled a MAP limit which is set lower than atmospheric pressure. Aqmar 1 Quote Link to comment Share on other sites More sharing options...

I was thinking of having a MAP limit when the ECT is low, but now I realize it was silly to control such a thing when I already have rpm limit to handle that. Thanks!

ellisd1984 Posted June 24, 2023 Report Share Posted June 24, 2023 There's a actual boost limit based on ect in the bost control section Quote Link to comment Share on other sites More sharing options...
