The classic system on my Cuda is super flexible and now made obsolete with the XFI version that will learn the VE fuel table just as the EZ efi does. Basically, you put in your target A/F ratio, and it learns the fuel map to hit that A/F ratio. My classic will compensate to hit the target A/F up to +/20%, but anything more and its off. And everything in the classic version has to be set-up and watched as it runs to tune.

Here is a pic of the engine.....Not for the faint of heart.
