tada0finalist Posted November 28, 2018 Report Share Posted November 28, 2018 I have a question for acceleration enrichment function. In case "sequential injection mode" and "accel mode" = "TP(Main)", What is the trigger to activate additional fuel injection by acceleration enrichment function?

Adamw Posted November 28, 2018 Report Share Posted November 28, 2018 When set to TP mode the trigger will be rate of change of TP. The setting "Accel sens" adjusts how much enrichment is added for a given rate of change. Quote Link to comment Share on other sites More sharing options...
tada0finalist Posted November 28, 2018 Author Report Share Posted November 28, 2018 Thank you for the quick reply. Could you confirm the following my understanding for the trigger is correct or not? Accel dead band: 5% dTP/dt=3% -> non trigged dTP/dt=5% -> trigged In addition, next question. I want to know calculation logic of additional fuel. I can understand "Maximum Acceleration Enrichment = Accel Clamp Value % x Accel Load Value x Accel Cold Value". However I can not find calculation formula for actual additional fuel in Help. Therefore I can not understand how to work "accel sense" for calculation of actual additional fuel. Quote Link to comment Share on other sites More sharing options...

Accel dead band: 5% dTP/dt=3% -> non trigged dTP/dt=5% -> trigged It would be dTP/sample. I only have a vague recollection that the sampling frequency for TP is 500Hz but I would need to confirm that with engineering as I dont remember clearly. So if deadband is set to 1% and the throttle moved more than 1% within 1/500seconds then it would be triggered. 0.5-1.5% would be typical deadband numbers I am used to seeing. 20 minutes ago, tada0finalist said: However I can not find calculation formula for actual additional fuel in Help.

I have never really needed to know this info so it is not something I have a lot of knowledge about. I suspect it is just an arbitrary unitless "factor" but I will see if I can get any more info from engineering if it is easy to understand. You can log or watch the parameter "Accel fuel" to get a pretty good idea of where it is working and how much fuel it is adding, I dont normally need any more info than that to get it working well enough.
