You have 8 outputs, so wire each injector to an output.
Then turn on Twin Injectors in Essential Map Settings. Use the 20x14 blend map.

Then blend the injectors as you need to.

Good afternoon, I think I explained badly, the injectors (8) are already running on the engine, what I need is a correct table.

Nothing wrong with that, other than at low rpm I wouldn't use the secondary. However you need really need to find what the engine likes on the dyno. I would add that some people always let 5% through lower set to keep the fuel flowing and ready. I feel that your dead times should be accurate also as you have twice as many

Also, not worth having secondararrys on until 75% throttle as you not looking for the benefit yet

Hi Rob, from the little that I understand, from 76% to 95% of the throttle external injectors are used.
Wouldn't injectors1 and injectors2 be better for getting more CV?

CV ?
You need to test on the dyno really as you are only looking for small gains
