actually at the bottom of the chart it says it flows 11% more on gas.....so 11% more on the 1178 is 1,307.58 so should i use that or is 1178 fine
There is easier approach to setting KRKTE. No need to use fancy calculators
If you don't change engine displacement just use this formula: NEW_KRKTE = (OLD_FLOW * OLD_KRKTE) / NEW_FLOW
No need to use factor with KRKTE. Just use pure HEX value from BIN (convert it to decimal for convenience).
It's important to use exact same units on both injector flows!
They must have the same flow unit (popular ones: cc/min, lb/hr, g/min) at the same pressure (popular ones: @3bar, @3.5 bar, @43.5psi etc.) and for the same reference liquid (Ethanol, n-Heptane, Gas, etc.)
Looks like your chart gives flow at 43.5 psi on ethanol (multiply by 11% for gas) in cc/min.
Now just find your stock injectors flow and "just" match units and you have your KRKTE.
Actually matching flow units is the most pain in the ass in this process
Then just paste new KRKTE value back to BIN and test drive the car and keep eye on fuel trims. If they are off in wide range then you have to shift your KRKTE.
You have to also recalculate KVB constant if you want cluster to show real values (the lower KRKTE the higher KVB proportionally).
