CoreyG Posted January 19, 2021 Share Posted January 19, 2021 Hi Everyone, I'm a data scientist by trade and have been considering throwing together a script that could aid in dialing in injector slopes, breakpoint and deadtime. The input would be a reasonable size datalog of AFR, injector pulse widths and such. Using some non-linear optimization, it should be possible to identify what variables need to be changed to minimize lambda errors. It should be possible to differentiate speed density errors from injector scaling errors, as the lambda errors will track with injector pulse width. I've only just got my wideband sensor working on the bench (long story... did you know there are 720 ways to wire up a 6 wire sensor?). So I'll be doing some logging and prototyping. I'd be happy to have anybodies input on this. 4 Quote Link to comment Share on other sites More sharing options...
