Grant Baker Posted December 11, 2017 Report Share Posted December 11, 2017 Hi Guys, Does anybody have the full characterisation data for these Siemens 830cc / 80lb injectors? https://www.fiveomotorsport.com/825cc-siemens-deka-iv-110324 Quote Link to comment Share on other sites More sharing options...

Grant Baker Posted December 11, 2017 Author Report Share Posted December 11, 2017 Doesn't show full characterisation though... It's for a car on modelled fuel strategy. Quote Link to comment Share on other sites More sharing options...

Adamw Posted December 14, 2017 Report Share Posted December 14, 2017 Ok, you can calculate that using the LSCOMP/HSCOMP. Heres what I get: Having said that, with a 830cc injector in a typical car engine, the ECU will unlikely ever access this table. I doubt it will be any different than having it full of zeros. integrale8v 1 Quote Link to comment Share on other sites More sharing options...

Can you show us how you calculate this? Maybe snart Excel sheet? Quote Link to comment Share on other sites More sharing options...

Here is a good visual explanation of how the Ford Hi Slope/Low Slope works: http://injectordynamics.com/articles/ford-injector-characterization/ I have a spreadsheet to do it but unfortunately it's not mine to share. Since we are looking at just the difference between two straight intercepting lines it is fairly easy to do with standard Excel tools. integrale8v 1 Quote Link to comment Share on other sites More sharing options...
