Most injectors should not be run beyond ~75-80% duty cycle because flow does not necessarily increase beyond that duty cycle.

Do you have some more info about that? How did you come to that conclusion?

Most injector data sheets show linearity drop off significantly after 80% or so (depending also on fuel pressure)

OP asked me to remove it for some reason.

I wish he'd have posted a github/gitlab repo instead of a binary.

Update:

Tested on 2 cars so far. My personal car with 0280158235 injectors, 4bar regulator, on e85...
calulator was 3% on the lean side

second test was a FID 1000 car on 4 bar regulator e85 and it was 3% on the rich side..

Earned my confidence as a benchmark base.  Will definitely prove valuable and expedite calibrations considering it took me 3-5 logs/runs to reign in the injector stuff.

Thank you kindly as it is effective in my perspective.

Can you provide the TVUB used for those injectors(xx235), the price is unbeatable on them but there is no TVUB really for them.

Also OP , can you maybe provide some source or source snipper on the formula used for the krkte and etc calculation I asssuming its taken directly from FR?
