Default 411 = 14 Ohm

Hi 92, the OEM GM "411" REQUIRES a 14 Ohm fuel injector as the PCM is fitted with a eight channel driver IC WITH Fault reporting required for OBD rules.

A TWO OHM fuel injector will not be allowed to operate due to the difference in current flow.

MOST, ALL, modern fuel injectors have a better designed magnetic circuit requiring LOW current.

I would like to supply your fuel injectors, Denso 650cc OR 850cc ? (flow matched)

What is your length requirement ?

Default Fuel Injector EV-14 Long 80.lbs

Hi 92, OK the EV-14 Long.
The EV-14 term is for the injector connector specification AC (American Car) or the Older EV-1 Bosch style choice is next ?

Post a picture of the injector electrical connector if you are not sure.
What fuel pressure will you operate at in the fuel rail ?
The fuel injectors I provide are Flow Matched (set of eight) along with a Dead Time Specification needed for some EMS calibrations.
