Re: Same cells too lean on WOT, too rich on partial throttle

BIN file posted above looks fine. Just the fuel tables appear as per picture above quite strange
Would suggest going back to stock BIN file (S13 KA24DE address file using here to view) and start again
Target AFR is what we display for an approximation of what the fuel table theoretically. However the main aim is to view this in filtered/raw view and adjust the numbers so that your target AFRs at wideband match what you are aiming for.
Also your fuel map should be smooth so when its reading four points and moving around the map that the resulting injection pulse width smoothly changes from point to point. The above map is too rough and will result in unpredictable AFRs especially going around the cells at 90/99 and 12/11
