Correcting my previous post, when you allow 20% correction - it IS 20% of full required fuel flow (DI + PI), when you apply the correction to the fueling to reduce your error you need to add fuel to either delivery system or both in the amount need to achieve the error.
So for example if you're running say 40% port and the Lambda Correction % you're trying to fix is 5% you need 5% more total fuel at that point.
If you have enough margin in your DI to add 5%, then you can just add 5% to BOTH your DI and PI flows values at that point.
If you want to add it with PORT only, you'll need to add:
5% + (5% x 60% / 40%) or whatever your DI/PI ratio is = 12.5% fueling to PORT ONLY to fix your Lambda error.
Actual calculation is 0.05 + (0.05 * 60/40) = 0.125
Sorry for that incorrect statement on my previous post (which I'll edit out), sometimes just too many numbers rattling around in my head...
