1999 engine
1.8l
550cc injectors

i used 160cid and 550cc/min and 14.7 and 4 cylinders/injectors
plugging those into the req_fuel calculator in tunerstudio, i get a req_fuel of 5.5.
After going through many threads on this ... people seem to be using around 11.

should i be using a different req_fuel number .. or did i mess something up with the calculator?

 

5.5 is correct.

 

Isn't 1.8L closer to 110 CID?

 

that may be what i have put in.. i can't remember the exact number. but the calc does spit out 5.5

 

its all the same, use 11 and have idle cells in your VE table that sit at 1%.
