S4 Harness with built in resister pack Fuel. Running 1600cc
 

Sitting in traffic the other day I realized that my car now has a weird configuration. I have a stock ECU S4 1988 with built in resister pack for the injectors. I have 550cc stock primary and 1600CC secondary ford injectors. Two low and two high impedance running on the 440.

Is there anything wrong with this configuration?

Hi Ian,

The 440 can run high or low impedance injectors with or without resistor packs as long as it's 1 injector per output. If the ECU doesn't get abnormally hot then I'd say you're fine.

Thanks.
