I finally gave up on the EZ EFI on Charley's cammer Fairlane. It runs and idles nice, drivability is good, but it just won't learn the harder throttle areas. Stays lean, fuel pressure is steady. This is a 700 HP twin throttle body setup and probably never should have been used on this combo.
Couple things I noticed. The fuel pump they gave him for 700 HP is only a 190L pump that will not support that power level in my opinion. Also, I was having big problems with pressure and a loud fuel pump, turns out the filter they gave him is a carb style solid phenolic type filter, can't even blow through it. Swapped to a real stainless EFI 40 micron (on the pressure side) and fixed that.
My opinion is this system should work well on mild to moderate setups, but you need to go to a programmable system beyond that. We're swapping to an XFI for the Fairlane.
