injector resistance changes - 12.5 to 14.5

[Jason Haines]

Does anyone know what effect, if any, going from a 12.4 Ohm to 14.5 Ohm
injector will have (like going from some GM to some Ford high impedance
injectors). I know this change is commonly made when switching between
different OE injectors but I was just wondering from an electronics point
of view and driver circuit point of view what this might do ( to
reliability, actual pulse width versus commanded pulse width, current/load
on the injector drivers, diagnostic system checks etc...).

PS - I realize that unless you have an ECU designed for low impedance
injectors you can't run low impedance (2 ohm) injectors with an ECU
designed for high impedance injectors (although some aftermarket ECU's are
designed to work with both).


Thanks,
