I think Henry might have beause I've seen a picture of a pump he's modified and pulled out all the volumetric correction. As an aside the 'racing' MFI pumps had no volumetric controls. The reason I ask is that I'm going to pull out the control circuit and control the rack with a servo driven by a megasquirt, an 'eMFI' system.

You might wonder why I'd bother, The MFI system has great fuel delivery (200 psi atomisation, sequential, independant of manifold pressure) , lousy control (levers, cams etc). If I do this I'll be able to 'tweek' the MFI system with the same accuracy of an EFI system, If I re cam the engine, I can remap the megasquirt. I'm also going to permanently install an LM-1 AFR
and run closed loop
