Turbo Diesel Injector Tuning

Postby VX L67 Getrag » Mon Dec 31, 2018 12:19 pm

Hi All,

I have a question about injector tuning, first is about the calculations for correct layout..
I have seen tables like this...

Calculated Injection.png (61.28 KiB) Viewed 480 times

But in raw floating point & is definitely 8Bit actually looks like this...

But there has got to be some weird calculation for it as it is inversing the numbers so a simple negative multiplication calc isn't going to do the job?

Then the next question is what's the best way to get best results for fuel tuning, injection manipulation or fuel pressure?

Every 1 difference makes 0.2 difference to the actual value.so i'd say something like divide by 5 and apply offset.
