Injector milliseconds calculator after pressure change
Injector milliseconds calculator after pressure change
Looking for a calculator to convert existing fuel map msec data following an increase in fuel pressure. I want to maintain existing AFR having discovered max duty cycle is too high. Had a copy of such a converter years ago on an old computer but can't find it. TIA.

Re: Injector milliseconds calculator after pressure change
Just run the engine and multiply/divide the entire map until AFR's are close to where they were.
A dyno box can be handy for that, will only take a few seconds.
Really if all you've changed is fuel pressure, it will hardly be a massive change anyway, and if you were running out of injector previously, tuning will probably all wrong under heavy load anyway and need re-done.
