Fuel table accuracy?

Recommended Posts

The fuel table has max of 22-rpm & 20 load axis points.
My question, is 500 rpm accuracy enough for the map? Does the ecu calculate the rpm/load values between the cells?
Is the fuel map really this coarse or is there some other values that fine tune the injection? map,iat,tps?

22 rpm increments gives you 500rpm resolution all the way up to 11,000 rpm.  Are you planning on running that high of a redline?  You can define the breakpoints so you have greater resolution where needed and less where you don't .  How many do you feel you really need though?

You will find, that when tuning, the box will appear over the current MAP/RPM location, it will either be over a certain cell, or crossing multiple cells.

when crossing multiple cells, it will take the average of the cells its crossing, so you don't get the fuel value jump as it goes cell to cell
