integrale8v Posted May 7, 2017 Report Share Posted May 7, 2017 Had a quick look and and it seems ok, But your map sensor must be faulty, it shows 116kpa with the engine off. You should also upload a log of the engine running/stopping, much easier to troubleshoot then. Eivind Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 8, 2017 Report Share Posted May 8, 2017 As well as what Eivind has mentioned, I also notice you have charge temp approximation and IAT trim turned on. Usually you only want one or the other so turn one of those tables off for now. Your master fuel number seems high considering the size of your injectors and non-sequential, have you confirmed fuel pressure is correct?If you can provide a short log and also post the trigger scope we should be able to help more.
